Abstract
QUESTION
One of my patients had a computed tomography scan of her abdomen a week ago and has 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 similar to that of the general population (ie, 1% to 3%).
摘要
问题
我的一位患者一周前做了腹部计算机断层扫描，刚刚发现自己怀孕7周了。我应该告诉她关于怀孕以及对胎儿的风险有哪些？
答案
您的患者不会因辐射暴露而增加流产或胎儿严重先天性畸形的风险。她的风险与普通人群相似（即1%至3%）。
