New Research Examines Radiation Risks with CT Exposure Prior to Pregnancy

Author(s)Jeff Hall

In a recent interview, Camille Simard, M.D., MSc, discussed findings from a new study assessing elevated risks of spontaneous pregnancy loss and congenital anomalies associated with CT exposure in the month prior to conception.

Exposure to a single computed tomography (CT) scan up to four weeks prior to conception was associated with an eight percent higher risk of spontaneous pregnancy loss and a six percent higher risk of congenital anomaly, according to new research published in the Annals of Internal Medicine.
