MeSH Sometimes you won't have to do more than fast; sometimes you'll have to drink stuff; sometimes you may even have to do bowel prep. Conclusion: Fat-suppressed techniques are highly useful, and optimal fat suppression is achieved with spectral adiabatic inversion recovery (SPAIR).16,23 T1W images are acquired before and after gadolinium-based contrast is administered in the arterial, venous, and delayed phases. However, MR Enterography has high costs, low spatial resolution and lack of widespread availability unlike CT Enterography which has quick scans times and costs are much lower.

Colorectal cancer accounts for 10% of all new cancers and 9% of cancer deaths. A screening program involving direct mucosal visualization by colonoscopy is commonly implemented for patients with pan-colitic UC, due to increased risk for colonic mucosal adenocarcinoma. T2-weighted signal increase is associated with inflammation and edema and is a marker of active Crohns disease.16 However, in CTE, active Crohns disease may look similar to chronic fibrotic changes.

A recent meta-analysis of CE and MRE demonstrated that CE was superior to MRE for proximal small-bowel Crohns disease.3 Additionally, multiple studies have demonstrated that CE is more sensitive than MRE for detecting small aphthous lesions.4,5,6 It is known that MRE has relatively decreased sensitivity for mild disease restricted to the superficial mucosa. MR Enterography says BOWEL: Wall Thickening (> 4mm): Terminal ileum extending for 4 cm in length On the other hand, the colonoscopy can't "see" or reach much beyond the first few inches of the end of the small intestine leaving some 19+ feet of small intestine unexamined.

Medical imaging in IBD Small-bowel follow through (SBFT) can evaluate the small bowel to detect stricture, fistula, and abscess. The major unmet clinical need is lack of a gold standard diagnostic test; diagnosis is typically made by a combination of clinical features, findings on endoscopy and histopathology, laboratory abnormalities, and imaging.

My sister had MRE (MRI Enterography) at Mayo Clinic. A recent study by Campari et al demonstrated good sensitivity (94%) but poor specificity (64%) for detecting actively inflamed colonic segments compared with ileocolonoscopy with biopsies.34 Another study by Ords et al demonstrated a sensitivity of 87% and a specificity of 88% for detecting disease activity in ulcerative colitis using endoscopy as the reference standard.35.

Recurrence and outcomes following hepatic resection, radiofrequency ablation, and combined resection/ablation for colorectal liver metastases. Single-shot T2W imaging combined with fat suppression employing the SPAIR technique provides optimal sensitivity and specificity for active Crohns disease.15,16,23 Earlier studies either did not use fat-suppressed T2 or did not use optimized fat suppression and may not have appreciated the full utility of MRE.4,36,37 Other forms of fat suppression, such as simple inversion-recovery or chemical shift spoiling, typically demonstrate higher noise, less uniform fat suppression, and increased through-plane motion sensitivity to bowel peristalsis.23 Although MRE is relatively insensitive to early disease, or disease confined to the mucosa, it is effective at evaluating the severity and extent of submucosal pathology and extra-intestinal complications.38 T2W imaging with fat saturation has shown high accuracy for measuring inflammation and acute disease activity compared to endoscopy, biopsy, and CT.
