X-ray during pregnancy: possible consequences and is there an alternative. X-ray examination of pregnant women in the early stages

X-ray diagnostics is one of the most informative methods for studying the sinuses, lungs and other organs. This procedure is often necessary for expectant mothers, for example, for dental treatment, injuries, or suspected pneumonia. If there are indications for examination in pregnant women, the question arises as to how harmful X-rays are to the embryo, and whether there are alternative diagnostic methods.

How does X-ray affect the fetus?

It has been proven that the baby in the mother’s belly is vulnerable to the effects of x-rays, especially during the period when x-rays are taken in the first weeks of gestation - during the formation of organs and tissues. That is why women’s concerns about the radiological examination method are well founded.

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

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

Is it possible to take x-rays during gestation?

The question of prescribing an x-ray for a pregnant woman is decided individually. When a woman’s life and health are at stake, you can’t do without it. X-rays are indicated for injuries, dental problems, suspected tuberculosis, and other serious situations. It is carried out only with shielding (applying special lead protection to the abdomen and chest area).

Pregnant women are recommended to have x-rays done using modern equipment, which is safer due to low radiation doses. Not all municipal clinics have the latest equipment, so you can contact private institutions for examination. It's better to be safe than to put your child's health at risk.

• conducting surveys on important indicators;
• use, if possible, other techniques (ultrasound, MRI);
• X-rays of the pelvis and abdomen are extremely undesirable; if necessary, the procedure is postponed to a later date;
• photographs of the skull and limbs are taken only after protecting the fetus (lead shielding), and the purpose of the examination must be justified.

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

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

In the early stages

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

In the later stages

After 16 weeks, the formation of the baby’s organs is completed. However, X-ray examinations cannot be carried out uncontrolled. The middle of the period is the optimal period for taking x-rays during dental treatment. In the third trimester, the uterus becomes sensitive to external influences. X-rays can be taken 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 values ​​(mSv) vary depending on the area of ​​radiation exposure:

• peripheral images - up to 0.1;
• dental studies - 0.02;
• digital panoramic image 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 harmful to an embryo, after receiving 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 photographs. If the equipment used to take pictures does not output more than 0.7 mSv, it is impossible to obtain a portion of radiation that is dangerous for a child.

Consequences and possible risks

High doses of radiation and regular X-ray examinations can negatively affect the formation of the embryo and lead to miscarriage. Possible consequences of radiation damage to the fetus:

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

Recent studies by American specialists suggest that x-rays during pregnancy 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 a pregnancy and be extremely careful after conception. In this case, there will be no need for emergency medical care and x-ray examination.

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

To maintain and have a successful pregnancy, it is important to eliminate 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 carry it out urgently in case of periostitis, painful eruption of wisdom teeth, suspected fractures of the limbs, or head injuries.

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

It happens that an X-ray examination needs to be performed not by the expectant mother, but by her eldest child. In this case, you should not be present in the X-ray room at the time the image is taken.

How often can pregnant women have x-rays?

Modern devices and highly qualified medical staff make it possible to prevent dangerous consequences of the procedure for the embryo and fetus. The total permissible exposure to radiation for a baby during 9 months of gestation is 0.3 mSv. This corresponds to a single examination of the lungs or 15 photographs of the teeth. If the treatment plan includes multiple X-rays of the abdominal cavity, the pregnancy must be terminated.

Is there an alternative?

Doctors are wary of prescribing X-rays for pregnant women. In some cases, the study is replaced with 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.
• Visiograph. A modern diagnostic device is equipped with a unique sensor that allows examination with a minimum dose of radiation. It is used in dentistry. The targeted beam flow allows you to safely perform dental x-rays during pregnancy.

X-rays do not always lead to dangerous consequences. However, the danger of this diagnostic method for the baby cannot be discounted. They resort to it in emergency cases, accurately calculating permissible doses and providing anti-radiation protection.

Pregnancy is a very important period in the life of every woman. The expectant mother must ensure normal development of the baby without complications so that the child is born healthy. Even a common cold causes great inconvenience, since most medications can negatively affect the development of the fetus. But what to do when treatment and examinations are really necessary? What to do in the case when the expectant mother needs to do?

X-rays make it possible to diagnose many things successfully. With their help, you can see internal organs, bones and other parts of the human body that cannot be studied using conventional methods. The invention of the X-ray machine gave a powerful breakthrough in medicine and improved the quality of life.

Every person knows that radiation in large volumes is dangerous. You can't be diagnosed with X-rays very often, but sometimes it is really necessary to make an accurate diagnosis. The beam affects the tissues through which it passes. This effect is very difficult to detect; a very significant dose of radiation is needed for irreversible processes to begin to occur in the body.

But what if we are talking about a human body that has not even been born yet? The expectant mother is exposed to enormous stress while carrying a child, and the baby is not yet adapted to the outside world.

Therefore, X-ray radiation can negatively affect its development and provoke various pathologies.

Many doctors say that it is necessary to avoid x-rays at all costs during pregnancy, even if absolutely necessary. Other experts argue that x-rays are not as dangerous as they seem, and the expectant mother can, if necessary, resort to this diagnostic method without fear.

Risk to the fetus

When an X-ray beam passes through living tissue, water molecules are ionized. Free radicals are formed, which can disrupt the processes in cells and their doubling. As a result, abnormalities may occur in chromosomes and cell death, turning them into cancerous and pathological ones. This does not happen immediately and very rarely, but such cases do happen. The developing fetus is very vulnerable, and this is what forces expectant mothers to avoid x-rays during pregnancy, since the risk of developing developmental pathologies increases significantly.

With strong radiation, genetic material is damaged on a huge scale, increasing the risk of miscarriage or the birth of a child with developmental disorders. That is why doctors advise avoiding it during pregnancy in order to reduce the risk of giving birth to a defective baby.

X-rays are most dangerous in the first trimester of pregnancy, since it is during this period that the child’s nervous system is being formed.

If any changes occur during this period, the child will be born sick in any case.In the second and third trimester, the risk decreases somewhat, since all the most important systems have already been formed, however, cell division is still actively occurring, so if irradiated at these times, the baby may get problems with the digestive system and hematopoiesis.

What to do if the procedure is necessary

X-rays are prescribed for dental diseases, fractures, dislocations of limbs, injuries to internal organs and other problems. An X-ray examination is prescribed to the expectant mother only in cases where it cannot be avoided, in situations where the risk of disturbances in the development of the fetus is less than the risk of development in the mother.

It is worth remembering that the closer to the organs the picture is taken, the more dangerous it is. But even x-rays can negatively affect the course. In any case, you should consult your doctor. Such examinations are prescribed when it is really necessary. You need to monitor and take care of your health so that there is no need to resort to such diagnostic methods, especially during this important period.

Many women have situations when pregnancy is detected after X-ray diagnostics, so in the future the expectant mother experiences unnecessary worries. In this case, you should consult your doctor about possible risks. You may need help from a geneticist to rule out the possibility of development.

Modern X-ray diagnostic devices are safer than their predecessors, but the harm from X-ray radiation is still undeniable.

In the first weeks, there is an unspoken rule among doctors “all or nothing.” In other words, there are only two outcomes: either the fetus dies from the radiation dose, or it develops further. This fact is sad, but remains true.

Possible consequences

X-ray examination can be dangerous during pregnancy, both for the health of the baby and for the health of the expectant mother. The most unfavorable are:

• Fluorography
• X-ray
• Isotope scanning

It is better to avoid these studies during this period, since in this case the irradiation area is very large and is located close to the organs. X-rays of teeth or extremities can be done with less concern, but risks cannot be completely eliminated.

X-ray radiation is most harmful to the fetus due to the fact that embryonic cells are constantly dividing. They form structures and systems that form all vital organs. If even a minor mutation occurs at this stage, the child will be born with pathologies.

It is highly not recommended to take x-rays in the first weeks. During this period, the child’s nervous system is formed. After the examination, the fetus leaves the uterus along with the resumption of menstruation, and the woman does not always realize that she was pregnant. Miscarriages in such situations occur with great frequency.

After the first month of pregnancy, X-rays may show a slowdown in the development of all internal organs, the risk of miscarriage decreases, but the baby will not be born healthy. After the sixth week, the baby will experience hormonal imbalances. In the seventh week, pathologies of the immune system are possible, and in later stages, diseases of the respiratory system, genitourinary system, heart and kidney failure.

Such consequences are not worth putting the unborn baby at risk.The increased vulnerability of the hematopoietic system persists throughout pregnancy. cannot be excluded at any time. Therefore, weigh the pros and cons several times with your doctor before taking an x-ray.

X-ray during lactation

After pregnancy, an equally important period begins in the life of every woman: breastfeeding a newborn. The mother must make every effort to ensure that the baby receives all the necessary substances from breast milk, eats regularly, does not experience allergic reactions, and the first weeks of life are as comfortable as possible for a person whose body is just getting used to our world.

Doctors note that X-rays do not in any way affect the quality of breast milk, so you should not be afraid of examinations during this period, but you need to remember about their harm for each person. The baby will not suffer in any way, which is the most important thing. It is better to focus all your efforts on maintaining the mother’s health, proper diet and a calm emotional environment.

Possible alternative research methods

Ultrasound is the safest method of examination during pregnancy

The determining dose is the radiation dose during the study. The body receives the highest dose during a computed tomography scan. Then come:

• X-ray of the spine
• X-ray of abdominal organs
• X-ray
• Fluorography
• X-ray for limb fractures
• Dental research

For a baby, only the last three positions are safe according to sanitary standards. However, this does not eliminate all risks. If a woman has had an x-ray and only then learned about her situation, some experts sometimes strongly recommend artificially terminating the pregnancy in order to eliminate the risk of giving birth to a defective baby.

An alternative is ultrasound.The downside is that it cannot be used in all cases. If you need to examine areas that are very difficult to see, ultrasound will not help.In any case, you should consult your doctor.

There are situations when you can postpone it to wait for the birth of the child.

At the same time, you should not walk around and endure severe pain and wait for childbirth, and only then see a doctor. There are problems that should not be delayed under any circumstances. In case of a fracture, an x-ray will have to be taken, especially if it is severe. You should also not delay with your teeth, especially since such an examination will have almost no effect on the future baby.You should never delay going to the doctor. During pregnancy, routine examinations should be regular and systematic. Remember that you are responsible not only for your life, but also for the life of your unborn baby.

Any pregnant woman at some point may find herself in a situation where she will need one or another X-ray diagnostic method, for example, when visiting a dentist, if pneumonia or pulmonary tuberculosis is suspected, for a broken bone, and for many other reasons. The question immediately arises: will an x-ray study harm the unborn child, because maintaining his health is the mother’s most important goal.

How does X-ray affect the fetus?

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 huge amounts of free radicals (mainly H+ and HO–), which are extremely chemically active. 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 fetal body, most cells are actively dividing (while in adults their percentage is much smaller), which causes the fetus to be highly sensitive 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 developing. For example, in the first weeks of development, the formation of the nervous system begins - if the fetus is irradiated at this time, there is a high risk of developing 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 the child, and in severe cases – to his non-viability.

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

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

Is it possible to take x-rays during pregnancy?

It should be noted that for diagnosing diseases in pregnant women, simple radiography is preferable; Due to higher radiation doses, computed tomography 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

How often can an x-ray be taken during pregnancy?

However, you should not think that x-rays during pregnancy are extremely dangerous and unfavorable. Take this calmly - 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 dental x-rays during pregnancy?

How dangerous is dental x-ray for the fetus? Modern models of dental X-ray machines are characterized by minimal radiation exposure. For example, after taking an X-ray of a tooth, a woman receives a radiation dose equal to 0.02 millisieverts (mSv), while during an air flight 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 radiation as for a dental x-ray. In addition, when X-raying teeth, a very limited area is irradiated, and the abdomen 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 a tooth, you can contact a clinic equipped with a visiograph. Compared to conventional X-ray machines, 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 dental x-rays for pregnant women, starting from the second trimester. After 12 weeks of development, the fetus becomes less sensitive to x-ray radiation.

What are the dangers of x-rays during early pregnancy?

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

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

In addition, when X-raying the head or limbs, the radiation has virtually 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). ) .

Taking these factors into account, it can be argued that x-rays performed out of urgent need are practically not dangerous to the fetus. Especially if protective equipment was used during the x-ray.

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

Doctors strongly recommend undergoing 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 undergo examinations during pregnancy and take medications that can negatively affect the baby’s intrauterine development.

What can replace x-rays during pregnancy?

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

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