Abstract
Abdominal imaging is a vital tool in the diagnosis and management of inflammatory bowel disease (IBD). Patients with IBD, especially Crohn’s disease (CD) typically undergo multiple diagnostic imaging tests throughout their disease course. This can result in significant cumulative radiation exposure, which may increase the risk of radiation-induced cancers. In this review, we will explore the risks of radiation exposure from diagnostic imaging, the scope of the problem in IBD, risk factors for higher exposure, and alternative approaches to imaging and treatment of the underlying disease that can reduce an IBD patient’s exposure to radiation. Utilization of diagnostic imaging modalities and techniques that minimize radiation exposure and optimal disease management to reduce need for these tests should be considered best practices in the care of patients with IBD.
