Abstract
Pregnant patients can receive allergy premedication prior to a contrast-enhanced computed tomography exam if the exam is indicated. The risks and benefits of allergy premedication for pregnant patients will be discussed, as well as imaging strategies for the pregnant patient with a contrast allergy. Alternative imaging including ultrasound, noncontrast magnetic resonance imaging, or noncontrast computed tomography can be diagnostic depending on the clinical scenario and is usually preferred, allowing physicians to avoid giving allergy premedication in pregnancy, a 13 h delay, and risking a breakthrough reaction.
