Core tip: Imaging plays a key role in the diagnosis and lifelong evaluation of a patient with inflammatory bowel disease (IBD). Several imaging modalities are available, each with a unique set of risks and benefits when considering cost, anesthesia risk in the pediatric population, ionizing radiation, image quality, and availability. In this article, we review the imaging techniques available for evaluation of IBD, with particular focus on judicious use of ionizing radiation. We also review current imaging guidelines among pediatric and adult patients with IBD.
