Radiation Exposure in IBD: How do we Minimize the Dangers?

Radiation exposure in IBD is increasing, particularly among patients with Crohn's disease (CD), primarily because of increased use of computed tomography (CT). The referring clinician and the radiologist share responsibility for the justification of radiation exposure, and there is an onus on medical professionals to keep exposure as low as possible. Radiation exposure in IBD can be minimized by limiting the use of imaging studies that involve ionizing radiation to those clinical situations where they are likely to change management, implementing advances in low-dose CT technology and using alternative imaging modalities that do not use ionizing radiation.
