Pregnancy should be the biggest and happiest thing in a family, but if you do something you shouldn’t do in the course of pregnancy, such as having a chest X-ray, then whether you can still continue the pregnancy and carry on this happiness is indeed something you need to weigh up. The effects of chest X-ray radiation on the fetus are as follows: 1. Chest X-ray is different from chest X-ray, and the amount of X-ray radiation is very difficult to estimate correctly. In early pregnancy pregnant women can receive two chest radiographs radiation is not teratogenic, but chest X-ray can not. The reason is that the chest X-ray exposure time is uncertain, can be long or short, the radiation dose is not good to accurately estimate; 2, the second is the irradiation field is uncertain, sometimes due to the need for diagnosis of the screen will be pulled down relatively low, can be up to the upper abdomen, so that the irradiation of the field of the lower edge of the location of the early gestational sac from the location of the pelvic cavity is less than a safe distance of 50 centimeters, so the risk of teratogenesis Therefore, the risk of teratogenicity is difficult to determine and assess. 3, when the fetus excessive exposure to this X-ray, easy to cause fetal miscarriage, death or deformity of the fetus. Therefore, try to avoid chest X-ray during pregnancy, and if you must have X-ray examination, you should try to avoid abdominal irradiation, and only take partial photos. Suspected abdominal problems, abdominal organs generally take ultrasound, compared to X-ray examination is more convenient and accurate. It is also important to note that during the 15th to 60th day (within 2 months) after conception, which is a critical time for the formation of embryonic organs, try to avoid some routine abdominal (pelvic) X-ray examinations. Pregnant women should take the health of the baby in the womb as the starting point for whatever they do, and do their best to protect their baby, ensure his healthy development and growth, and avoid too much exposure to x-rays.
