The breath hold 3-D gradient echo (3D GRE), T1W, and single-shot, T2W techniques are useful for bowel imaging.15 The high signal of diseased bowel becomes much more conspicuous if the adjacent fat is darkened by fat suppression.23 We use a multi-echo Dixon technique, which provides improved fat suppression with higher in-/out-of-plane resolution and contiguous bowel-segment imaging with improved contrast and edge sharpness. Usefulness of Colon Assessment by Magnetic Resonance Enterography in Pediatric Patients with Inflammatory Bowel Disease-Retrospective Case Series.

Dark-lumen MR colonography with fecal tagging: a comparison of water enema and air methods of colonic distension for detecting colonic neoplasms. Examination may be limited by luminal bowel gas, although this can be reduced by fasting and oral administration of intraluminal contrast.8 Although the ileocecal region and colon are often easily visualized, additional portions of the small bowel can be difficult to see due to overlying bowel loops. Magnetic resonance enterography has good inter-rater agreement and diagnostic accuracy for detecting inflammation in pediatric Crohn disease.

Endoscopy is more sensitive for detection of the early-manifesting mucosal abnormalities seen with IBD and enables histopathologic sampling. Wall thickening and abnormal enhancement were sensitive indicators of Crohn's disease (75% and 78%), while abnormal T2 signal, mesenteric vascular prominence and adenopathy were specific (86%, 91% and 93%). MR colonography with limited bowel preparation: patient acceptance compared with that of full-preparation colonoscopy. I hate colonoscopies, but I think they are a neccasary evil. Compared to CTE and MRE, ultrasound poorly demonstrates the extent of abnormalities and demonstrates poor longitudinal comparison between studies.9, Computed tomography enterography (CTE) generally demonstrates greater availability and lower initial costs compared with MRE; however, the overall cost benefit remains incompletely evaluated. MR Enterography has sensitivity to bowel motion alongside T2-weighted sequences which aids the challenge of imaging the bowel. 2011 Feb;9(2):124-9. doi: 10.1016/j.cgh.2010.10.019. Radiographics.
