According to the American College of Radiology, many insurers fully cover (with no copay) CT colonography in certain cases. 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. ago.

If the esophagus and stomach are reflected in a very detailed way by means of a tomography, then choosing what is best - an MRI or a colon colonoscopy, it is better to give preference to the latter option. It is also called MR enterography. Sinha R, Rawat S. MRI enterography with divided dose oral preparation: Effect on bowel distension and diagnostic quality. MR imaging of the small bowel is indicated for patients with Crohn disease, those for whom exposure to radiation is a concern, those with contraindications to CT, and those with low-grade small-bowel obstruction. As a rule, modern hardware methods are recommended, since they are the most informative. 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.

MRIs can't take biopsies, they can't remove a polyp and as of late 2008 they still weren't as accurate as a CTE for the small intestine. Magnetic resonance (MR) enterography is a clinically useful technique for the evaluation of both intraluminal and extraluminal small bowel disease, particularly in younger patients with Crohn disease. 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.
