Motherisk update - Ionizing radiation during pregnancy

Question One of my patients had a computed topography scan of her abdomen a week ago and had just found out she is 7 weeks pregnant. What should I tell her about the pregnancy and the risk to her fetus? Answer Your patient is not at increased risk of miscarriage or major congenital fetal malformations due to radiation exposure. Her risk is to that of the general population (ie. 1% to 3%).
