Colonoscopy is better at detecting polyps, large and small. It has been established that the diagnostic accuracies of FCP in colonic CD are generally considered to be different than those of small bowel CD; mucosal inflammation in the colon elevates FCP levels higher than mucosal inflammation in the small bowel [7,8,9,10,11,12, 14, 15]. Crohns Disease (CD) is a discontinuous transmural inflammatory disease that can involve the whole gastrointestinal tract and it is part of inflammatory bowel disease group. [Magnetic resonance colonography: a new diagnostic tool]. To survey the perceived indications for magnetic resonance imaging of the small bowel (MRE) by experts, when MR enteroclysis (MREc) or MR enterography (MREg) may be chosen, and to determine how the approach to MRE is modified when general anaesthesia (GA) is required.

All CT enterography and MR enterography examinations that are performed in patients with Crohn disease should include the entire rectum, anal canal, and perineum Balanced FFE (axial and/or coronal) in breath-hold, T1 pre- and post-contrast (axial/coronal) in breath-hold. Crohn's disease is characterized by inflammatory lesions in the gastrointestinal tract, most commonly in the terminal ileum and colon. Magnetic resonance imaging does not cope with the task because of the anatomical features of the intestine - the presence of multiple bends and loops, which are superimposed on each other.
