Cross-sectional imaging with CT and MRI is increasingly being used to evaluate IBD due to their capacity to assess submucosal and deeper tissues of the bowel and to evaluate for extra-intestinal manifestations. Cronin CG, Lohan DG, Mhuircheartaigh JN et-al. It involves filling the bowel with fluid that will show up bright on the images and makes the small bowel stand out. 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. There may be other risks, depending upon your specific medical condition. Given the nuances of the implementation of the measures under consideration, it becomes clear that colonoscopy is the most informative way of diagnosing any intestinal diseases. Only sounding allows you to accurately assess the state of the described area of the digestive system. virtual colonoscopy (vc), also known as computed tomography colonography (ctc), is an effective method for detecting small (6-9 mm) and larger (10 mm) polyps.

My GI sent me for an MRI a couple years ago rather than a CT. Radiation is cumulative and repeated CT studies are not appropriate for non-emergency follow-up. Perfusion imaging has been shown to provide high diagnostic accuracy when combined with T2W images and postcontrast images.24,25 Perfusion imaging requires specialized scanning techniques or perfectly timed arterial, venous, and delayed phase enhancement, which raises the technical challenge of whole abdomen and pelvis imaging.

My MRI showed that I had thickening in the lower intestines so I am going in for a colonoscopy to figure out how bad it is andwhat medicine I will be put on. Also, the procedure is a better test to view soft-tissue problems. MR enterography offers the advantages of multiplanar capability and lack of ionizing radiation. The breath hold 3-D gradient echo (3D GRE), T1W, and single-shot, T2W techniques are useful for bowel imaging.15 The high signal of diseased bowel becomes much more conspicuous if the adjacent fat is darkened by fat suppression.23 We use a multi-echo Dixon technique, which provides improved fat suppression with higher in-/out-of-plane resolution and contiguous bowel-segment imaging with improved contrast and edge sharpness.
