Thus, the patient is relieved of the need to re-conduct the procedure to clarify the nature of the build-up or tumor. Unlike regular X-ray images, CT enterography is able to provide detailed images of tissue and structures, such as bone and blood vessels. In the subset of 162 patients who underwent colonoscopy within 30 days of MRE, the overall sensitivity remained 85% but the specificity increased to 85% (kappa=0.69).

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. A comprehensive examination of inflammatory bowel pathology can be provided with a combination of MRE and endoscopic techniques. , Griffiths AM, Turner D, Walters TD, Feldman BM ) doi.: MR imaging may be performed with enterography or enteroclysis good candidate for a capsule endo April..
