Answer to Question #11461 Submitted to "Ask the Experts"

Category: Pregnancy and Radiation — Exposures not directly to embryo/fetus

The following question was answered by an expert in the appropriate field:


I'm one month and 10 days pregnant. On the fourth day after my last ovulation, I went for a computed tomography (CT) brain scan. Is there any problem in continuing my pregnancy? How much risk does the CT scan pose to this pregnancy?


There is no risk in continuing your pregnancy. The radiation from a CT scan is in a very thin beam, and there is very little, if any, scattered radiation below the neck. There was no radiation exposure to your abdomen from this brain CT scan.
