Inflammatory bowel disease is more common in North America and Western/Northern Europe, and is thought to affect approximately 1.4 million people in the U.S., and as many as 2.5 million to 3 million in Europe.1 Both UC and CD are typically diagnosed in children or young adults, although CD is sometimes diagnosed in a smaller subset of patients between 60 and 80 years of age. Of these, 310 patients also underwent colonoscopy with biopsy(s) within 90 days. If a large tumor is found on colonoscopy and blocks passage of the scope, CT colonography allows a thorough check of the entire colon. Parallel imaging enhanced MR colonography using a phantom model.

Neubauer H, Pabst T, Dick A, et al. AJR Am J Roentgenol. 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.

The probe used during the study is equipped not only with a miniature video camera that broadcasts an image to a medical monitor. government site. Ugeskr Laeger. Figs. PMC Radiographics. Compared to CTE and MRE, ultrasound poorly demonstrates the extent of abnormalities and demonstrates poor longitudinal comparison between studies.9, Computed tomography enterography (CTE) generally demonstrates greater availability and lower initial costs compared with MRE; however, the overall cost benefit remains incompletely evaluated. Role of spectral presaturation attenuated inversionrecovery fat-suppressed T2-weighted MR imaging in active inflammatory bowel disease. The headphones will also block the noise from the scanner.

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.
