The effects of CT in pregnancy on the fetus may lead to fetal growth restriction, fetal malformation, or even fetal death in severe cases. However, it also depends on the gestational week of pregnancy. If CT is done in early pregnancy, within 1-14 days, the effect is less. It also depends on the purpose of the CT. If the CT is done to enhance the lower abdomen, it will have a greater impact on the fetus; if the CT is done within 2-4 weeks, it will also have a greater impact on the fetus because during this period, when the brain or important organs are taking shape, irradiation of CT can easily cause malformations to the embryo’s development, resulting in fetal abortion and other cases. If CT is done during pregnancy, it is important to consult your doctor and consider whether to keep the fetus or to terminate the pregnancy by abortion according to the doctor’s advice to avoid adverse consequences.
