Any pregnant woman at some point may find herself in a situation where she will need one or another method of X-ray diagnostics, for example, when visiting a dentist, if you suspect pneumonia or pulmonary tuberculosis, a broken bone, and for many other reasons. The question immediately arises - will the X-ray examination harm the unborn child, because maintaining his health is the main goal of the mother.

How does X-ray affect the fetus?

Let's first try to understand the difference between the body of an adult and a child, and then figure out how x-rays can affect both. X-rays - high-energy electromagnetic waves - have the ability to penetrate the least dense tissues of the body, and stay denser, giving an image of their contours - this property has found wide application in modern radio and x-ray diagnostics.

Passing through tissues whose cells are in a state of division, X-ray radiation damages them from the inside, breaking and destroying DNA chains - the main carrier of genetic information. X-rays partially ionize the water inside the cell, which leads to the formation of a huge amount of free radicals (mainly H + and HO–), which are extremely reactive. They attack intracellular nucleic acids and proteins, literally tearing them apart. The result of this is the emergence of a non-viable or (worse) mutant cell - and the more of them, the higher the likelihood of developing anomalies.

In the body of the fetus, most cells are actively dividing (whereas in adults their percentage is much less), which causes the high sensitivity of the fetus to ionizing radiation.

X-rays have the most adverse effect on the tissues and organs of the fetus at a time when they are just being formed. For example, in the first weeks of development, the laying of the nervous system begins - if the fetus is irradiated at this time, there is a high risk of developing a persistent organic pathology of the nervous system - microcephaly, underdevelopment of certain brain structures - the cerebellum, hippocampus, cortex, which in the future can lead to impaired mental functions child, and in severe cases - to his non-viability.

At 5-6 weeks (during the laying of the adrenal glands), irradiation can provoke their underdevelopment or insufficiency at a later age. At 4-8 weeks of pregnancy, when the formation and development of the heart takes place, ionizing radiation can lead to numerous defects in its valvular apparatus or to defects in the very foundation - the heart muscle. At 6-7 weeks - to a violation of the formation of the thymus gland and severe immune deficiency. At 11-12 weeks - to the suppression of the functioning of the bone marrow, the development of acute leukemia or severe anemia.

Thus, the most dangerous X-ray examination is precisely during the laying of the main tissues and organs - in the first trimester of pregnancy. In the future, the danger of this procedure decreases - however, even then pathologies from the blood system (the most common of them is anemia) and the child's gastrointestinal tract (persistent stool disorder, difficult to treat) cannot be ruled out.

Is it possible to do an x-ray during pregnancy?

There is no single answer to this question. An x-ray examination is indicated in case of emergency situations, when, without it, the probability of severe complications or even death of the mother is extremely high. In addition, in case of fractures of the bones of the extremities, for example, X-ray diagnostics is carried out simultaneously with careful shielding (the imposition of special protective covers, aprons, pads on the pelvis, abdomen and chest).

It should be noted that for the diagnosis of diseases in pregnant women, it is most preferable to have a simple radiography; computed tomography due to higher radiation doses and radioisotope methods should not be used here, in principle, especially since there is a much safer alternative - ultrasound.

The influence of x-rays on the development of pregnancy

Although modern devices for X-ray diagnostics are much safer than their counterparts used several decades ago, when X-raying the abdomen and pelvic organs of a pregnant woman, the fetus receives a certain dose of radiation, which, of course, affects its further development. The greater the radiation exposure to the fetus, the higher the likelihood that an abortion will occur within the first few hours after the procedure. However, in the early stages (even before the formation of organs), the so-called “all or nothing” rule applies - the fetus either dies from a massive dose of radiation, or continues its further development.

How often can x-rays be taken during pregnancy?

The most ideal option is to avoid any radiation exposure, not to undergo any X-ray studies during pregnancy. However, this is not always possible to achieve. There is a rule that the total radiation exposure to the fetus during pregnancy should not exceed 0.3 mSv, which roughly corresponds to a single examination of the lungs (X-ray). If the fetal exposure level is much higher than this value (30 mSv or more - this situation can occur during repeated X-ray procedures, in particular - with multiple fluoroscopy of the intestines, bladder, etc.), doctors most often recommend terminating the pregnancy .

However, do not think that x-rays during pregnancy are extremely dangerous and unfavorable. Take it easy - if possible, avoid exposure to ionizing radiation during pregnancy, if x-ray diagnostic procedures are vital - use all available protective measures - this will minimize the harmful effects of radiation on both you and your child.

Is it possible to take an x-ray of a tooth during pregnancy?

To the question: “Is it possible to do an X-ray of a tooth during pregnancy?”, Dentists answer: “It is possible, but it is undesirable in the first trimester.” If the doctor has the opportunity to cure a tooth without a picture, he will definitely do it. However, in some cases, an x-ray is required, for example, with a fracture of the tooth root, with a gum (tooth) cyst, or with root canal treatment.

How dangerous is a dental x-ray for a fetus? Modern models of dental x-ray machines are characterized by minimal radiation exposure. For example, taking an x-ray of a tooth, a woman receives a dose of radiation equal to 0.02 millisieverts (mSv), while when flying over medium distances (2500 km) - 0.01 mSv. Thus, if a pregnant woman flies on vacation to the sea, she will receive the same dose of x-ray exposure as when x-raying a tooth. In addition, when x-raying the teeth, a very limited area is irradiated, and the stomach and the fetus itself are reliably protected by a lead apron that does not transmit x-rays.

If there is an urgent need to obtain an image of the tooth, you can contact the clinic equipped with a visiograph. Compared to a conventional X-ray machine, its radiation exposure is 10 times less and amounts to 0.002 mSv.

But still, in order to completely eliminate the pathological effect on the fetus, doctors recommend taking an x-ray of the tooth for pregnant women, starting from the second trimester. After 12 weeks of development, the fetus becomes less sensitive to x-ray exposure.

What is dangerous x-ray during early pregnancy

Indeed, X-rays are dangerous during early pregnancy, especially in the first 12 weeks, while all organs and tissues are being formed. Prolonged exposure to high doses of radiation over 1 mSv can cause various abnormalities in the development of the fetus.
Timing Possible Complications
1-2 weeks Stopping cell division and death of the embryo
Ectopic pregnancy
3-4 weeks Pathological formation of extra-embryonic organs (chorion, amnion and yolk sac), which ensure the viability of the embryo, leads to termination of pregnancy in the early stages
4-5 weeks A failure in the laying of stem cells, which are the basis of all future tissues, can lead to significant developmental anomalies.
Heart defects
Thyroid Developmental Disorders
Anomalies in the development of the liver
5-6 week Anomalies in the development of limbs
Pathologies of the hematopoietic system (spleen and bone marrow)
Organic disorders of the nervous system
Congenital diseases of the digestive system
Immune disorders, frequent purulent infections with damage to the thymus
Violations of the formation of the gonads
Endocrine pathologies associated with disruption of the pituitary gland
7 week Hematopoietic disorders (anemia) caused by liver damage
Anomalies in the development of the small intestine
Significant metabolic disorders with damage to the adrenal glands
8 week Anomalies in the development of the upper lip and upper jaw - "cleft lip", "cleft palate"
Pathologies of the development of joints and finger phalanges
9 week Ovarian Developmental Disorders
Bronchial damage
10 week Pathologies of tooth development
11 week Defects of the heart and joints
Disturbances of skin sensitivity and smell
12 week Weakening of immunity with damage to the thymus
Growth retardation and slow metabolism are caused by abnormalities in the structure of the thyroid gland

Let's hasten to reassure expectant mothers, the table below is rather theoretical information. In fact, the probability of damage to the embryo during an X-ray examination is negligible, because during the diagnosis, the woman and the fetus are exposed to short-term exposure to low doses.

According to sanitary standards the dose received by the fetus should not exceed 1 mSv, at the same time when carrying out radiographs it is:

  • chest - 0.3 mSv;
  • limbs - 0.01 mSv;
  • nasal sinuses - 0.6 mSv;
  • teeth - 0.02 mSv.


In addition, with x-rays of the head or limbs, radiation has practically no effect on the mother's abdomen. Reliable protection is an apron that protects the fetus from x-rays.

More dangerous are x-rays of the pelvic region, spine and intestines (6-8 mSv), fluoroscopy (over 3 mSv), and computed tomography (10 mSv). ) .

Considering these factors, it can be argued that an x-ray performed out of urgent need is practically not dangerous for the fetus. Especially if protective equipment was used during the x-ray.

Is it possible to do x-rays when planning a pregnancy?

An X-ray when planning a pregnancy cannot damage the egg and cause the development of anomalies in the unborn child. The dose of radiation that the female body receives during x-rays is considered safe. Therefore, even if there is a need for multiple studies, the eggs remain completely safe and a healthy fetus develops after fertilization.

Doctors strongly recommend that you undergo a medical examination (including x-rays or fluorography) at the planning stage in order to identify hidden pathologies that may manifest themselves during pregnancy. The fact is that a pregnant woman's immunity decreases, which leads to an exacerbation of chronic diseases. Therefore, it is better to treat the disease during planning than to be examined and take medications during childbearing that can adversely affect the intrauterine development of the baby.

What can replace an x-ray during pregnancy

Doctors, if possible, try to avoid prescribing various diagnostic procedures to expectant mothers, since their impact is not fully understood. However, there are situations when the disease and the experiences associated with it can be much more dangerous for the fetus than examination and treatment. In these cases, doctors try to replace x-rays during pregnancy with safer procedures.


More dangerous for a pregnant woman and her unborn child such diagnostic studies:

  • computed tomogram;
  • fluorography;
  • fluoroscopy;
  • isotope scan.
These procedures are associated with more powerful radiation and are contraindicated at all stages of pregnancy. If such studies were carried out in the early stages, before the woman found out about her pregnancy, then the gynecologist may recommend terminating the pregnancy.

X-ray diagnostics is one of the most informative methods for examining the sinuses, lungs and other organs. Often, this procedure is necessary for expectant mothers, for example, for dental treatment, injuries, suspected pneumonia. If there are indications for examination in women in position, the question arises of how harmful X-rays are to the embryo, and whether there are alternative methods of diagnosis.

How does X-ray affect the fetus?

It has been proven that the baby in the mother's stomach is vulnerable to the effects of X-rays, especially during the period when the X-ray is performed in the first weeks of gestation - during the laying of organs and tissues. That is why women's fears about the radiological method of examination are quite justified.

Why does X-ray radiation affect the body, what is its main danger? Under the influence of electromagnetic waves with high energy, ionization of water in tissue cells is observed. This results in the release of free radicals. This process disrupts cell division, provokes the destruction of DNA molecules (carriers of genetic information).

In the body of the embryo, cells are actively dividing, which explains its high susceptibility to radiation. A change in their structure leads to abnormal development of organs, malignant neoplasms, malformations of the nervous system, and genetic failures.

Is it possible to do an x-ray during gestation?

The issue of prescribing an x-ray for a pregnant woman is decided individually. When the life and health of a woman is at stake, it is indispensable. X-rays are indicated for injuries, problems with the teeth, suspected tuberculosis, and in other serious situations. It is carried out only with shielding (imposing special lead protection on the abdomen, chest).


Pregnant women are advised to take x-rays using modern equipment, which is safer due to low doses of radiation. Not all municipal clinics have the latest devices, so for the purpose of examination, you can contact private institutions. It is better to be safe than to endanger the health of the child.


  • conducting surveys on important indicators;
  • use, if possible, other techniques (ultrasound, MRI);
  • an x-ray of the pelvis and abdomen is highly undesirable, the procedure, if necessary, is postponed to a later date;
  • pictures of the skull, limbs are taken only after protecting the fetus (lead shielding), while the appointment of the examination must be justified.

During the procedure, a woman may not know about conception. What if she found out about the pregnancy after a delay, and the day before she took an x-ray? To avoid such situations and prevent exposure of the embryo in the first weeks, it is important to follow the general rules:

  • it is advisable to perform a planned study within 2 weeks after menstruation, before ovulation;
  • during the procedure, protect the chest and abdomen with a lead pad, even if the fact of pregnancy has not yet been confirmed.


In the early stages

Radiological studies carried out during the planning of conception do not affect the development of the egg. The portion of irradiation is low, which excludes chromosomal abnormalities. During the first 16 weeks of gestation, X-rays can have a detrimental effect on the fetus and cause severe malformations. At this time, the procedure is performed only if indicated. Studies that can be postponed are planned for the 2nd and 3rd trimester or postpartum period.

At a later date

After 16 weeks, the formation of the child's organs is completed. However, it is impossible to conduct an X-ray examination uncontrollably. The middle of the term is the optimal period for x-rays during treatment at the dentist. In the third trimester, the uterus becomes sensitive to external influences. X-rays can be done in the presence of injuries, toothache and other situations that require emergency medical intervention.


Permitted radiation doses

When prescribing an x-ray for a pregnant woman, it is advisable to consult a geneticist. The doctor will assess the degree of risk and take into account the radiation dose that the patient will receive during the examination. Radiation indicators (mSv) vary depending on the area of ​​radiation exposure:

  • peripheral images - up to 0.1;
  • dental research - 0.02;
  • digital panoramic picture of teeth - 1.5;
  • fluorography - 0.3;
  • x-ray of the spinal column - 8;
  • examination using a tomograph - 10.

According to SanPiN, a radiation dose of 1 mSv is detrimental to an embryo, after which a miscarriage or the birth of a child with severe pathologies is possible. This is a fairly high dose, which can be obtained after taking about 50 dental X-rays. If the equipment with which the pictures are taken does not output more than 0.7 mSv, it is impossible to receive a portion of radiation that is dangerous for the child.


Consequences and possible risks

High doses of radiation and regular x-ray examinations can adversely affect the formation of the embryo, leading to miscarriage. Possible consequences of radiation damage to the fetus:

  • malformations due to irreversible changes in the central nervous system (mental retardation, microcephaly, etc.);
  • chromosomal abnormalities;
  • malignant tumors;
  • malformations of the heart, liver, thyroid gland;
  • anemia in a newborn, abnormalities in the work of the digestive organs;
  • pathology of bone tissue;
  • smell disorder.


Recent studies by American experts suggest that X-rays during childbearing increase the risk of having a child with insufficient body weight by 5%. Why this happens is not exactly clear. Experts urge women to plan pregnancy and be extremely careful after conception. In this case, there will be no need for emergency medical care and x-rays.

What to do if you can not do without an x-ray?

For the preservation and successful course of pregnancy, it is important to exclude the effects of radiation on the body. However, it happens that without an urgent x-ray it is impossible to make a correct diagnosis. It is important to urgently carry out it with periostitis, painful eruption of wisdom teeth, suspected fractures of the limbs, and head injuries.

If the study cannot be postponed, it is better for the pregnant woman to agree to conduct it in compliance with all safety standards. You can first consult with a gynecologist and geneticist. You should tell the specialists why the x-ray is shown, and what dose of radiation will be received.

It happens that an X-ray examination must be performed not for the expectant mother, but for her older child. In this case, you should not be present in the X-ray room at the time of taking the picture.

How often can pregnant women have x-rays?

Modern devices and highly qualified medical staff make it possible to prevent the dangerous consequences of the procedure for the embryo and fetus. The cumulative allowable exposure to radiation for a baby during 9 months of gestation is 0.3 mSv. This corresponds to a single lung exam or 15 dental scans. If the treatment plan includes multiple abdominal x-rays, the pregnancy must be terminated.

Is there an alternative?

Doctors carefully prescribe x-rays to women in position. In some cases, the study is replaced by safer procedures:

  • MRI. This method is based on a magnetic field, the action of which does not lead to mutations in the protein structures of cells. However, MRI is not recommended for early pregnancy.
  • Ultrasound. The ultrasound technique will replace x-rays when examining the abdominal cavity, joints, legs, lymph nodes, and thyroid gland.
  • Visiographer. A modern diagnostic device is equipped with a unique sensor that allows you to conduct an examination with a minimum dose of radiation. It is used in dentistry. A targeted stream of rays allows you to safely perform an X-ray of the tooth during pregnancy.

X-ray does not always lead to dangerous consequences. However, the danger of this diagnostic method for the baby cannot be discounted. It is resorted to in emergency cases, having accurately calculated the permissible doses and providing anti-radiation protection.

Pregnancy is a wonderful and at the same time exciting process for every woman, the joy of which can be overshadowed at any moment. After all, no one is immune from the occurrence of various diseases or injuries that require an X-ray examination to establish a diagnosis.

It is not surprising that the need to undergo an x-ray during pregnancy can alert and even scare the expectant mother, since taking care of the baby's health is always in the first place. Of course, it is not necessary to draw hasty conclusions and abandon the procedure, but it is necessary to understand in detail so as not to panic when it is prescribed!

X-ray radiation and its effect on the fetus

As has long been known, according to the tragic experience of Hiroshima, Nagasaki and Chernobyl, the radiation field carries a radiation load on the body, which leads to multiple violations of the cellular structure. As a result, people often develop various pathological processes. The X-ray method is based on the ability of rays to penetrate and linger in the dense tissues of the human body, which, in addition to being beneficial, can sometimes be harmful.

Passing through cells that are in a state of division, the rays cause a violation of DNA chains - the main carriers of genetic information. X-ray radiation ionizes the cellular fluid containing water in its composition, while releasing chemically active radicals. The latter affect proteins and intracellular acids, which leads to cell mutation or even cell death. When a large number of mutation-altered cells are formed, various anomalies arise.

And what then can threaten the fetus in the womb with radiation exposure? For a developing embryo, exceeding the dose of X-ray radiation will lead to irreversible consequences, given that its cells are in constant division. This makes the embryo even more sensitive to X-rays with their ionizing effect.

At what stage of pregnancy is it most dangerous to do x-rays?

The most dangerous x-ray in the early stages of pregnancy, when the laying of the organs and systems of the fetus. The first weeks of conception are characterized by the beginning of the formation of the nervous system, and if fluoroscopy (examination with x-rays) is done at this time, the likelihood of developing microcephaly, an irreversible organic pathology, increases significantly. There is also a high risk of underdevelopment of some brain structures - the hippocampus, cerebellum, cortex, which can subsequently cause the baby's mental disability.

Severe forms of such disorders often lead to fetal death both during pregnancy and in the first months of life.

The fifth and sixth weeks are the period of laying the adrenal glands, and an x-ray during pregnancy at this time can provoke their underdevelopment or deviation in further formation. From the fourth to the eighth week - the laying and development of the fetal heart occurs. At this time, radiation exposure sometimes leads to a violation of the structure and shape of the valvular apparatus (heart defects), as well as to defects in the muscle tissue of the organ.

Violation of the shape of the interventricular septum is one of the most common birth defects

At 6–7 weeks, the passage of an x-ray during pregnancy is dangerous for the development of thymus pathologies and a pronounced decrease in immune function. The procedure done at 11-12 weeks can become a factor in suppressing the activity of the bone marrow, as well as provoke the development of a severe form of anemia and even acute leukemia.

Thus, it turns out that it is most undesirable for the fetus to undergo an x-ray during pregnancy in the early stages, since in this period the main organs and systems of a small person are being laid. In the later stages, the dangerous impact of diagnostics decreases, but the likelihood of hitting the hematopoietic system, which is expressed in the development of anemia and pathologies of the gastrointestinal tract, still remains high.

What if research is needed?

The duration of the period of gestation by a human female is quite large, and during this time many unforeseen situations can happen - diseases or injuries, in which treatment can only be prescribed after an x-ray. What should a woman in a position do in such a situation? The very first thing is to calm down and not panic, worrying about whether it is possible to take an x-ray during pregnancy.

It is better to find out and know the following points related to the features of this procedure, including:

  • dose of radiation that can lead to impaired fetal development;
  • the most dangerous periods of pregnancy for fluoroscopy;
  • features of the protection of the fetus and closely located organs of a woman;
  • ways to minimize radiation exposure using modern equipment.

Of course, no one prescribes such a diagnosis to people without indications, and a doctor can strongly recommend an x-ray for pregnant women only in case of urgent need. The examination is indicated in the event of emergency situations, the consequences of which can be serious complications with a threat to the life of the mother, and, consequently, the fetus.

It is also mandatory for fractures of limbs or other injuries that allow the use of shielding - protection with the imposition of lead aprons, casings or linings. For diagnosing pathologies in pregnant women, conventional radiography (creating images using x-rays) is preferable, since computed tomography (CT) gives much more radiation.

It is forbidden to use for examination of women in the position not only CT, but also various methods using radioisotopes, due to their harmful effects on the body of the mother and fetus. If it is necessary to take an x-ray both in the early stages and in the later stages, an ultrasound or magnetic resonance method is often used, in most cases allowing an accurate diagnosis.

Radiation doses received during the examination of various organs and parts of the body

If the pathology is of such a nature that the ultrasound and magnetic resonance method does not help to get a complete picture of the state of the organ, then you will still have to resort to x-rays during gestation. You should not worry too much that it is dangerous for health and development, since images of many parts of the body are created with low exposure, unable to affect the fetus.

According to the accepted sanitary and hygienic standards of the Ministry of Health, the maximum allowable dose of irradiation to the fetus should be no more than 1 mSv so that the negative effects of X-rays do not develop. Approximately the fetus receives on x-ray:

  • legs or arms - 0.1 m3v;
  • tooth and jaw area - 0.02 m3v;
  • lungs - 0.3 m3v;
  • abdominal cavity and small pelvis - 6 m3v;
  • spine - 8 m3v.

Whereas computed tomography exposure is 10 m3v, so they try not to prescribe it when carrying a child. But if, for example, you need to take an x-ray during a fracture or a visit to the dentist, then you can absolutely not worry about it. Moreover, lead protection will be necessarily imposed on the abdomen.

According to the degree of danger of the radiograph for the fetus, 3 groups are distinguished, differing in the amount of exposure during its implementation:

  • High degree of danger. It is characteristic for the study of the abdominal cavity, spine and pelvis, since the baby is located in the path of X-rays and is directly exposed to them.
  • Medium danger. Occurs when diagnosing the lungs and chest, head, arm or leg. Although the rays do not fall on the fetus, the mother receives a rather high dose of radiation, so the area under study is large.
  • Minimum degree of danger. It is observed when taking pictures of the tooth, nose and sinuses, because X-rays affect pregnancy very little due to the need for small doses and small areas of the examined areas.

The most sparing examination of the organs of the third hazard group is also due to the diagnostics on specialized devices that carry a much lower load than conventional equipment.

Modern x-ray machines require minimal doses of radiation to create images. The strongest and most harmful effect is exerted by radiography in the first trimester of pregnancy, more specifically, in the first two months of embryo development. After the onset of 16 weeks of gestation, radiation exposure will no longer lead to significant impairment of the child's health.

The main thing for a woman in a position is to understand that a doctor will never recommend an x-ray during early pregnancy, as this is forbidden. The only condition for his appointment can only be a serious threat to the life and health of the mother, or a decision not to save the fetus.

What happens if a woman has an x-ray without knowing she is pregnant?

If the subject did not know that she was pregnant and took an x-ray in the first two weeks, then, according to some experts, the best solution would be to terminate the pregnancy. At the same time, doctors try to assess all possible risks as accurately as possible, specify what type of study it was, and find out the received radiation dose.

All information is compared and a decision is made about the possible danger to the bearing of the fetus. If, with a detailed calculation of the term of conception, it turns out that the radiography was carried out before the start of the expected menstruation, then there is no reason for concern. Otherwise, experts recommend conducting medical diagnostics and finding out if the mother and her baby have been harmed.

Are conception planning and x-rays compatible?

It is considered ideal if a woman, deciding to become pregnant, listens to the recommendations of doctors to undergo a complete examination of her body. After all, the process of bearing can reduce the quality of the functioning of the immune system, which will provoke the occurrence or exacerbation of various diseases. Therefore, it is worth identifying all possible pathological processes in the body and treating them in advance.

X-ray when planning pregnancy is an integral part of a comprehensive diagnosis, allowing you to check many of the reproductive organs responsible for the possibility of conception. And also provides a check of all other parts of the female body. Radiography in this case does not have a detrimental effect on the egg and on the development of the future embryo, since the dose is negligible, that is, insufficient for the occurrence of genetic abnormalities. This ensures, even with repeated procedures, the complete safety of the egg, from which a healthy embryo can develop during fertilization.

Are x-rays harmful during lactation?

The need to undergo an examination during breastfeeding usually worries young mothers, which, according to experts, is completely in vain. X-rays have absolutely no effect on the composition and quality of breast milk, and also do not disrupt the process of its production and do not change the amount.

So do not worry about this, and if there is a need for an examination if a pathology is suspected, then you should not hesitate, but undergo an x-ray. This will enable the doctor to establish a diagnosis as soon as possible, and prescribe the necessary therapy.


The calm state and good mood of the mother have a great influence on the development of the fetus.

The most dangerous x-ray diagnostics

Given that the X-ray method carries a certain danger to the mother and fetus, there are several methods that are characterized by an even higher radiation exposure. This:

  • fluorography;
  • fluoroscopy;
  • computed tomogram;
  • isotope scan.

If such procedures were carried out, and then the woman found out about her pregnancy, then the obstetrician-gynecologist may recommend an artificial abortion, citing a high probability of complications. It is especially dangerous to carry them out in the early stages.

Alternative Methods

Of course, doctors in most cases try not to prescribe X-ray diagnostics and other methods with various types of harmful effects on the body of the mother and child. Since any, even a long-used method, has not been fully studied and there is always the possibility of its possible effect on cellular structures. But, if we oppose the danger of radiation and the deep feelings of the mother about the presence of any disease and its consequences for the baby, then the latter can have a stronger effect on her health.

There are several alternative and safe methods that can, in some cases, save a pregnant woman from undergoing x-rays. These include the following types of diagnostic procedures:

  • MRI. Its magnetic field does not violate the structure, the ongoing processes in the cellular DNA of the embryo and does not cause their mutation. For all the time the use of MRI in diagnostics, not a single case has been identified when this procedure would have an impact on the development of a child in the womb. But still, doctors, explaining the lack of testing for pregnant women, do not recommend undergoing an MRI in the first trimester.
  • ultrasound. The advantages of ultrasound are its complete safety for the child and the possibility of carrying out at any period of gestation for examination of the abdominal cavity and small pelvis, muscles, ligaments, joints, lymph nodes and thyroid gland. The downside is the inability to conduct a high-quality diagnosis of bone structures.
  • Visiographer. A modern X-ray machine equipped with a sensitive sensor used instead of film. Thanks to this technology, the radiated power is significantly reduced. The device has a relatively small size, and its weak point beam beam allows you to assess the condition of the teeth and their roots, minimizing exposure.

The latest methods of radiography, carefully studied information about whether pregnant women can undergo x-ray diagnostics and ways to minimize radiation exposure will become a reliable guide for a woman during this wonderful and exciting period. And if it turned out that for certain reasons it became necessary to undergo this procedure, then it is worth arming yourself with knowledge or consulting in detail on all issues of concern with a specialist.

X-ray during pregnancy is not recommended, but not prohibited. It is prescribed only in case of a serious danger to a woman's health, for example, if there is a suspicion of tuberculosis, pneumonia, or fractures. Such a study can cause the rapid development of various pathologies in the fetus, so doctors, if possible, do not prescribe x-ray diagnostic methods, replacing them with safer alternatives.

In addition, X-rays are not used when planning pregnancy, delays, in the absence of confidence in a failed conception. Aggressive radiation causes changes at the cellular level, causes various pathologies of the fetus. Therefore, a woman needs to take care of her health in order to eliminate the need for such a diagnosis at any time.

X-ray during pregnancy is prescribed in exceptional cases, when other methods do not show an accurate result. Such a diagnosis is necessary if there is a threat to the life of a woman. Most often, a picture according to indications is taken in the following cases:

  • suspected pneumonia;
  • in order to confirm or refute tuberculosis infection, determine the location and size of lesions;
  • dental problems, in particular, of an inflammatory nature;
  • complex fractures of the legs, arms (shielding of the chest, pelvic area is necessary);
  • multiple fractures of the ribs, pelvis.

Pelvic and lung x-rays are more likely to cause lesions than peripheral studies. If possible, the doctor replaces x-rays with other diagnostic methods, such as MRI or ultrasound.

X-ray and pregnancy planning

Pregnancy after an x-ray can be left, but a woman must understand all the risks associated with this. But do not think about the bad in advance, modern digital X-ray equipment guarantees greater safety than previously used film. In addition, the doctor must take all measures to protect the fetus, pre-calculating the permissible radiation dose or replacing the study with a safer one.

X-rays and pregnancy planning are incompatible concepts, radiation has a negative effect even on a healthy body. Therefore, whenever possible, safer diagnostic methods should be preferred.

It is impossible to say unequivocally whether x-rays affect conception for women. In the first week, the “all or nothing” rule applies, that is, the embryo that received a dose of radiation will either die immediately or begin to develop. But the resulting exposure can still affect the health of the fetus, that is, it will require observation by a gynecologist-geneticist until childbirth.

To avoid undesirable consequences, when planning, you should follow simple rules:

  • go for x-rays in the first two weeks of the menstrual cycle, when the likelihood of pregnancy is minimal;
  • use protective measures (shielding, diaphragming) of the organs of the reproductive system.

If there is no certainty in the absence of pregnancy, then the doctor must assume that fertilization has occurred, and carry out appointments according to this assumption.

Is it possible to do an x-ray during pregnancy

Only a doctor can determine how an X-ray study affects pregnancy. If such a diagnosis cannot be avoided, for example, if a serious injury to the pelvic bones is suspected, it is necessary to carefully dose the radiation and observe all precautions. When scanning the area of ​​the head, upper and lower jaw, nose, additional protection of the abdomen and chest areas is required.

The attending physician should explain to the expectant mother whether an x-ray is dangerous during pregnancy, whether this examination can be replaced by another. Such types of diagnostics as CT and fluorography are strictly prohibited, they can cause irreversible changes, mutations up to the death of the fetus. In some cases, radiography is allowed:

  • in the presence of dangerous pathologies and fractures;
  • if other methods cannot replace this type of diagnosis.

The doctor's decision to perform an x-ray for a pregnant patient is based on several factors:

  • type of diagnostics;
  • gestational age;
  • the severity of the evidence;
  • possible consequences of refusing the procedure.

The maximum allowable dose is 30 m3v, but if this norm is exceeded, especially with multiple studies, it is recommended to interrupt the gestation.

X-ray in early pregnancy and its consequences

The most dangerous is an x-ray during early pregnancy, its consequences are irreversible, can lead to the death of the fetus. Before the delay and in the first eight weeks, that is, in the first trimester, radiation causes mutations at the gene level, teratogenic factors lead to pathologies of the cervical spine, nervous system, and developmental disorders of the brain.

An x-ray at the 2nd week of pregnancy is the most critical. At this time, the active formation of the fetus and its internal organs takes place, and aggressive radiation causes disturbances in their development. At this time, radiography can cause the death of the embryo and spontaneous abortion.

In general, between the fourth and eighth weeks of pregnancy, an active process of laying the main organs and systems of the unborn child takes place: the nervous, cardiovascular systems, kidneys, limbs. At the end of this period, the intestines and lungs are formed. Harmful effects on the mother's body entail the appearance of defects of varying severity, up to the death of the embryo and miscarriage.

How does x-ray affect the fetus

X-ray during pregnancy causes irreversible changes in the cells of the fetus, which become non-viable or begin to mutate. This is due to the fact that radiation penetrates through thin layers of tissues, but is retained by dense ones. In the picture, seals can show not only the contours of bones and organs, but also a variety of pathologies.

When passing through thin tissues, X-rays cause intense cell division and breaks in DNA chains, activating a large number of free radicals. In addition, X-rays are chemically active, they are able to trigger a variety of reactions that adversely affect the general condition of tissues.

X-ray examination for a pregnant woman is contraindicated, since ionizing radiation actively affects the fetus, causing cell mutation. For an organism in the formative stage, such changes are very dangerous, especially for the nervous system. The transmission of X-rays through the mother's body in the first trimester can also lead to underdevelopment of the brain, non-viability of the fetus.

The physiology of the human embryo is such that the effect of ionizing radiation is perceived too sensitively, it is amenable to changes at the gene level. Moreover, the shorter the gestation period, the stronger the consequences of such influence. The fetus that develops in utero for less than eight weeks has the greatest vulnerability. After nine weeks, the risk of abnormalities decreases, but does not disappear.

Radiology in the later stages is also dangerous, but the likelihood of developing pathologies in the unborn baby is somewhat reduced. The organs of the gastrointestinal tract, the cardiovascular system are at risk. The least dangerous is an x-ray of the arm and leg; in such studies, the abdomen and pelvis are shielded using a lead apron.

Possible risks when taking x-rays

The effect of x-rays on pregnancy is extremely negative, especially in the early stages, when the lesion can affect the brain and spinal cord, nerve centers. They are in the stage of active formation, therefore they are most vulnerable to X-ray radiation. Fluorography in the second week of pregnancy in general often leads to the death of the embryo and miscarriage.

After the fourth week, among the most likely pathologies: microcephaly, diseases of the yolk sac, temporary organs, as well as chorion, amnion.

After the sixth week, teratogenic factors are dangerous, leading to disruption of the organogenesis of the thyroid gland, adrenal glands, and liver. Among the most probable are complications in the form of hormonal dysfunction, damage to the walls of blood vessels, and valvular heart disease.

From the seventh week, exposure to ionizing radiation causes birth defects such as immune deficiency, malformations of the spleen, gastrointestinal tract, and bronchi.

After the twelfth week, the most common negative effects of fluoroscopy are anemia, leukemia, and severe bone marrow dysfunction.

After the ninth week, the so-called fetal, that is, fetal, period of embryo development begins. The harm of ionizing rays at this time is much lower than in the first trimester. All the main organs and systems have already been laid, so the risks of defects are minimized, but not completely excluded. The fact is that an x-ray at a later date is still dangerous because it can provoke a lag in the mental development of the baby and even the onset of an oncological process. In this case, the corresponding symptoms may appear much later. That is why, if possible, it is better to postpone the radiography until childbirth, or at least take it as late as possible. In this case, the rule applies: "The later - the better."

How to keep your child safe

To exclude abortion, spontaneous miscarriage, the development of various malformations in the fetus, the doctor, when prescribing radiography, must follow the requirements of SanPiN 2.6.1.1192-03 (the document regulating the conduct of studies using radiation):

  • total exposure cannot exceed 100 m3v, the allowable dose for two months is up to 1 m3v, otherwise termination of pregnancy is recommended;
  • if a woman decides to leave the child, all possible negative consequences are explained to her, screening is prescribed to identify possible developmental anomalies;
  • when prescribing an x-ray, the doctor must assess all the risks to the health of the woman and the fetus, if there are threats to the life of the expectant mother, then the examination is carried out, but with the maximum possible protection.

In order to protect the unborn child, X-ray examinations for pregnant women are prescribed only in emergency cases.

To protect the organs of the fetus during x-rays, special measures should be taken, such as shielding (covering the abdominal area with a lead apron) or diaphragming (organizing an artificial barrier to the penetration of x-rays). Such methods are applicable if images of the skull, lungs or limbs are prescribed, in other situations it is recommended to replace X-rays during pregnancy with ultrasound. Of particular danger is screening of the abdomen and pelvis (X-ray of the lumbar spine, pelvic organs, excretory urography, and the like). If the situation allows, they try to postpone the procedure until the third trimester or delivery.

When prescribing a study based on x-ray exposure, specialists take into account the following approximate doses of radiation:

  • for peripheral images - up to 0.1 m3v;
  • X-rays of the spine - 8 m3v;
  • dental research - 0.02 m3v;
  • general fluoroscopy - 3 m3v;
  • examination of the abdominal cavity - 6 m3v;
  • fluorography of the lungs - 0.3 m3v;
  • Plain computed tomography - 10 m3v.

The most dangerous are X-ray studies in early pregnancy:

  • isotope scanning;
  • general fluoroscopy;
  • fluorographic photographs.

With all these methods, radiation is used, which causes the development of pathologies. To protect the child, doctors prescribe ultrasound, MRI, which successfully replace x-rays in various cases and do not adversely affect the health of the unborn baby.

Unfortunately, alternative forms of diagnosis are not always effective. So, if if urolithiasis is suspected, excretory urography can be replaced by ultrasound of the pelvic organs, then with lesions of bone structures, ultrasonic and magnetic resonance methods are powerless.

Computed tomography is a form of diagnostics, which is also based on the transillumination of the tissues of the human body with x-rays. Considering it as a safe alternative is impractical. But the principle of operation of magnetic resonance imaging is the effect of a magnetic field on hydrogen atoms that make up the tissues of the body. Although this method is more gentle, it is not recommended to prescribe it in the first trimester, since the teratogenic effect of such an effect on the fetal egg has not been fully elucidated.

If fluoroscopy cannot be avoided, the geneticist must correctly calculate the maximum allowable dose and take all measures to protect the fetus.

Is it possible to do x-rays during lactation

It is undesirable for pregnant women to take an x-ray, but this restriction does not apply to the period after childbirth, while the woman is breastfeeding. Radiography does not affect the composition and quality of mother's milk in any way, that is, it does not interfere with lactation. However, the frequency of examinations should still be limited, since exposure to high doses adversely affects the health of the patient herself.

FAQ

When is X-ray not allowed?

You can not refuse the study if there are suspicions of serious pathologies that may threaten the life of a woman. At the same time, you can take a picture only as prescribed by a doctor, an x-ray will have a lesser negative effect if fluoroscopy of peripheral organs is performed.

When taking a picture of the limbs, shielding is used - the abdomen and chest are covered with a lead apron, the affected area will be visible, and the fetus is protected.

How often is radiography allowed during pregnancy?

Experts do not recommend x-rays at all. If the image cannot be avoided, you should notify the doctor about your condition. The maximum allowable radiation dose is up to 30 m3v, the recommended one is 10 mSv. Upon reaching this figure and multiple images of the abdominal cavity, the pelvic area, the doctor will recommend termination of pregnancy. Not only the study being conducted will be important, but also the fact that the pregnant woman was standing next to the apparatus without shielding. Even a single image taken can cause the development of various malformations in the fetus.

Let us give an example of calculating the radiation load. So, if a woman took x-rays of the lungs twice on a digital device, the resulting radiation dose will not exceed 40 μSv, or 0.04 mSv. This value is within the acceptable range, so termination of pregnancy in this situation is not mandatory.

What to do if the study was carried out before the fact of confirmation of pregnancy?

If a patient had an X-ray but did not know she was pregnant, could this have negative consequences? In such a situation, a consultation of a geneticist and a gynecologist is needed, observation until the moment of delivery. Performing even a single shot at the stage of the fetal egg is fraught with serious consequences. The only exception can be peripheral scanning with the use of reproductive organs protection. More research is needed to rule out negative consequences for the child.

In the initial 6-8 weeks after fertilization, the expectant mother may not be aware of what happened. If she nevertheless underwent x-rays out of ignorance, you should not worry in advance. In this situation, a positive attitude is important. There are many examples when pregnant women, despite the X-ray passed, bore a healthy baby.

X-ray exposure during pregnancy is dangerous. The type of study based on such a physical phenomenon is not recommended. If possible, try to find a safe alternative. A picture is taken only when there is a real danger to the life or health of a woman. In this case, the doctor takes all measures to protect the fetus.

X-ray examination is a valuable diagnostic procedure that helps to visualize organs and tissues in a non-invasive way (through the penetration of rays through the human body).

The study is carried out for all patients, but they prefer not to prescribe an x-ray during pregnancy due to possible adverse effects on the fetus.

X-ray during pregnancy: what you need to know about the diagnosis

This is a fairly significant dose of research, to get it, you need to try very hard. For example, one hundred x-ray examinations of the tooth can be completed at this dose.

Considering that an X-ray at an early stage of pregnancy will just catch the process of active cell division of the fetus, doctors do not advise putting pregnant women at risk once again.

This can provoke anomalies in the development of the fetus, intrauterine disorders, deformities.

Doctors note that in the first month of pregnancy, the fetus only lays the main systems and organs.

This is still an inferior heart, lungs, nervous system or musculoskeletal system, but the process of cell differentiation gives rise to their formation in the baby's body.

If the mother’s body is irradiated at the 1st week of pregnancy, then the cells of the fetus are susceptible to such exposure and may acquire abnormal signs.

In the first months of intrauterine development, the adrenal glands, the heart are formed in the child, the foundations of the immune system are laid.

If X-rays affect such cells, it will further lead to a weakening of the baby's health.

The second and third trimesters are safer in terms of examination. The risk of pathologies during intrauterine development is reduced, since cell differentiation has already occurred, the child has formed organs and systems, which in the rest of the time only grow, strengthen and develop.

Doctors note that X-rays in the second and third trimesters can also be unsafe and cause abnormalities in the blood and digestive system.

It is difficult to determine the pathologies that an x-ray will provoke, but doctors are more afraid of underdevelopment of the brain and pathologies of the nervous system - this will forever make the child disabled and socially passive in society.

Having learned about the possible effect of x-rays on the fetus, pregnant women often refuse to study, which is fundamentally wrong.

The described negative effects are possible, and the risk of developing fetal anomalies is extremely negligible.


Modern diagnostic equipment is safe. The bulky X-ray units, which gave a large dose of radiation, are long gone.

Now there is a possibility of dosed use of X-rays, low-dose studies are being done that will not affect the body.

This does not mean that pregnant women can have X-rays whenever and wherever they want. Research by scientists shows that an X-ray in the first week of pregnancy can terminate a pregnancy, because when irradiated at the stage of attachment to the uterus, the fetal egg becomes unviable and does not develop further.

Often women do not know about pregnancy, going for an x-ray, so the next menstruation is not perceived as a conception failure.

At the same time, the study has not yet been completed, and whether the X-ray is to be blamed for the failure of the pregnancy has not yet been proven.

Due to the high teratogenicity of the rays, physicians prefer to postpone the x-ray until a later date.

There are several tips to help remove the effects of radiation from the body. Red wine and milk are considered effective against the rays.

Of course, red wine in a delicate position will have to be abandoned, but milk will not harm the pregnant woman in any way and will help remove free radicals. Doctors give the following advice:


How often to take x-rays for pregnant women

If there is no indication for an x-ray, then it should not be done. Even with a fluorographic study, you can wait if the time has come to do a new screening.

Therefore, the question of the frequency of shots during pregnancy should be considered from the point of view of extreme necessity and a possible reduction in dosage.

Pregnant women should not be afraid of single shots, for example, if a woman has broken her arm, then you can’t do without an X-ray of your arm. It will be safe and radiation diagnostics in the treatment of teeth.

At the same time, if there is an alternative to x-rays, it is better to use such research methods. Radiation sessions for the treatment of oncological pathologies are prohibited.

Alternative to x-ray

If it is necessary to take x-rays for women during pregnancy, do not despair - you can choose an alternative examination that does not harm the child.

If there is no urgent need for an x-ray at 2 weeks of pregnancy, the doctor will suggest an ultrasound or magnetic resonance imaging.


 MRI

Ultrasound is safe at any period of fetal development, so it is prescribed to pregnant women without fear. The minus of ultrasound is the inability to see the bones and the difficulty in passing the gaseous medium.

Therefore, it will be difficult to see the fracture, to examine the digestive organs. Doctors often choose MRI - it gives a high-quality image and is safe during pregnancy.

Is it possible to do an x-ray during pregnancy - the main question for women who are faced with the need for diagnostics during the period of gestation.

Doctors say that X-rays are dangerous only in the first trimester, and in the later stages, small doses will not harm the child.

Therefore, when diagnosing, women should selectively approach the procedure and take into account all the features.
