Key Points Question What are the trends over time in the use of medical imaging (computed tomography, magnetic resonance imaging, angiography and fluoroscopy, and nuclear medicine) during pregnancy in the United States and Ontario, Canada? Findings In this cohort study conducted over a 21-year follow-up period (1996-2016), computed tomography use rates increased by 3.7-fold in US sites and 2.0-fold in Ontario, whereas use rates for other imaging modalities with ionizing radiation decreased. Overall, 5.3% of pregnant women in US sites and 3.6% in Ontario underwent imaging with ionizing radiation, and 0.8% in US sites and 0.4% in Ontario underwent computed tomography. Meaning The use of computed tomography during pregnancy has increased substantially over the past 2 decades and should be monitored to avoid unnecessary exposure of women and fetuses to ionizing radiation.
