Computed Tomography Exposure and Risk for Adverse Outcomes in Future Pregnancies

The use of computed tomography (CT) scans in medicine continues to increase (1), and adverse events related to CT scan–associated radiation are not well understood. Recent studies have focused on oncogenic effects (2). Because this research is based on modeling using data from Japanese atomic bomb survivors and radiation workers, it can be controversial (3). These models depend on transparency from the U.S. Department of Defense regarding the effects of their weapons on survivors, as well as data from military personnel exposed to radiation during testing.
