I believe that you are not unfamiliar with X-rays, either when you are sick or when you are having a health checkup, you need to have this X-ray. X-rays are a very common way of examining the body, as the pictures are taken by penetrating radiation. A normal X-ray does not have any negative effects on the body’s health, but rather has a positive effect on treatment. If your body needs an X-ray, don’t feel any psychological burden, even if you are pregnant. Of course, it should be clear that pregnant women belong to a special group of people, and unnecessary tests, whether harmful or not, are not recommended, and this includes X-rays, but this does not mean that X-rays have an effect on pregnant women. If during pregnancy because of the need for disease, or trauma really need to do X-ray examination, and there is no other alternative way, can be at ease to do X-ray examination, if just take a picture of an abdominal X-ray film, about only 0.5 rads of the radiation exposure, the impact on the fetus is minimal. What is more, there will not be any harm such as deformity of the baby or poor brain development as a result. Even if something like this occurs, it is not necessarily caused by having an X-ray. It is important to realize that even if a pregnant woman does not receive X-rays during pregnancy, the same 4-6% of newborns will have various types of malformations. If a pregnant woman needs to have an X-ray to check her body during pregnancy and doesn’t do it, it affects her health, and this is not good for the development of the fetus, either. The health of a pregnant woman is important not only for herself but also for the fetus. There are so many checkups during pregnancy, like routine dental X-ray, head X-ray, limb X-ray and chest X-ray, including mammography, head and chest CT will not cause damage to the fetus, just that we are too afraid of hurting the fetus, that’s why we are afraid of these checkups. Necessary tests should be done well, not necessary tests, try not to do, this is the principle of pregnancy examination.
