The high radiation exposure in CT Enterography (CTE) is a growing concern in imaging. The improvement in bowel MR opens the possibility of using this modality. The purpose was to compare the diagnostic accuracy of MR-Enterography (MRE) to CTE. Mural and extra mural radiological features were evaluated. Thirty six patients had MRE and CTE within 6 months. MRE correlated well with CTE having similar accuracies: 100%, 91%, 89%, 72%, and 65% for abscess, bowel wall thickening, phlegmon, luminal narrowing, and fistula, respectively. Therefore MRE should be recommended in young and pregnant patients in whom radiation exposure is particularly hazardous.
