When pregnancy meets X-rays, what should I choose?

It’s a clichéd topic, but not necessarily one that everyone encounters. As a radiologist, I often get asked about the choice between X-rays and pregnancy, and I even have friends who call long distance from thousands of miles to ask specifically about it, with nothing more than: what should I do now that I found out I’m pregnant after taking the film some time ago? It’s true that every mother wants to meet the right baby at the right time, whether it’s a careful preparation or an accidental harvest, and the right time is when the embryo is planted without contamination, drugs, radiation, etc. That said, even if it is pollution-free, drug-free and radiation-free, the baby is not necessarily the right one, not necessarily the perfect and flawless angel you want. My cousin, who did not undergo any prenatal checkups in the rural area at the time, was born with two congenital anomalies: spondylolisthesis and clubfoot, and later underwent two corrective surgeries at 6 months and 6 years of age. I keep thinking that if it were now, I would probably be induced and discarded. What kind of sadness and helplessness is this? Why can’t human beings accept imperfections in life? Usually, if an X-ray was taken shortly before the pregnancy and you consult a doctor, even the top professors and specialists will not tell you whether to “stay” or “abort”, it is a matter of all or nothing probability. If the baby is still stumped by the X-rays will lead to deformities, then I’ll give you a brainwash! The cell phones, computers, TVs and airplanes we travel on in our daily lives are all radioactive, and you don’t want to be completely isolated from them just because you’re pregnant, right? I once met a doctor who had to walk around the entrance of the radiology department of the hospital. So don’t regret maybe a minuscule shot, and don’t be ignorant and blind to active abortion, never, never! X-rays are divided into harmless dose, therapeutic dose, damaging dose and lethal dose. According to clinical guidelines from the American College of Radiology, the American College of Obstetrics and Gynecology, and the U.S. Food and Drug Administration, the vast majority of diagnostic x-rays are usually harmless to the fetus, such as a single extremity or chest x-ray, and a single CT examination of a non-abdominopelvic area. In general, the maximum fetal dose of X-rays is 5000 mrad, while the fetal dose of a single chest X-ray is 0.02-0.07 mrad, a single abdominal and pelvic X-ray is about 100 mrad, and a single mammogram of a pregnant woman is 7-20 mrad. The radiation dose to the fetus for a single CT examination of the head, chest, extremities, etc. is generally less than 1 rad, and the radiation dose to the fetus for CT examinations of the abdominal pelvis and lumbosacral spine is about 3.5 rad. In early pregnancy (8-25 weeks), X-rays at doses well above 5,000 mrad beyond the diagnostic range can cause adverse pregnancy, resulting in miscarriage or fetal growth disorders, central nervous system malformations, or even malignant tumors. Frankly, even if the fetus does not receive X-rays, there is a certain probability that malformations will occur. When a pregnant mother needs to undergo exposure to X-rays due to illness, such as routine oral radiographs, X-rays of the head, chest, limbs and breast, and CT examinations of non-abdominopelvic areas, the dose of diagnostic X-rays is still safe and there is no need to worry about whether the baby in the belly is being damaged. In some cases, if a pregnant woman must undergo X-rays or CT examinations of the abdomen and pelvis, she can communicate with her doctor and weigh the pros and cons.
