Additionally, MRE is further improved with additional refinements in fat suppression such as multi-echo Dixon 3D GRE, DWI, and perfusion techniques. Gastrointestinal prokinetic agents, such as erythromycin or metoclopramide, may be administered to speed gastric emptying.21,22 Recent research suggests that the sensitivity to bowel wall pathology related to CD is adequate even without bowel distention.15 At our institution, oral contrast use is not mandatory, and we rely on the high level of bowel wall contrast, achievable by MRE, to detect active or chronic IBD. Ask your doctor when to stop eating and drinking. MR technology is better at imaging soft tissue (such as fistulas), and it does not use ionizing radiation. Masks are required inside all of our care facilities. I hate colonoscopies, but I think they are a neccasary evil.

Diagnostic imaging in Crohn's disease: comparison of magnetic resonance imaging and conventional imaging methods. Due to the fact that a special apparatus with a microscopic chamber (colonoscope) is inserted directly through the anus to the end of the dome of the cecum, discomfort may occur, although local anesthesia is preliminarily performed. If a large tumor is found on colonoscopy and blocks passage of the scope, CT colonography allows a thorough check of the entire colon. 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.
