Radiation Doses from Small-Bowel Follow-Through and Abdominopelvic MDCT in Crohn's Disease

Abstract

Organ and effective doses are up to five times higher with MDCT than with SBFT. Crohn's disease is more frequently imaged with CT. For a subset of patients who undergo numerous CT examinations, efforts should be made to minimize the number of CT examinations, decrease the CT dose, or consider MR enterography.
