PURPOSE: This paper discusses the diagnostic yield of multislice computed tomography (MSCT) in @entity29 . METHODS: Contrast media are administered intraluminally (colon, small intestine) and intravenously (triple contrast CT). Filling of small bowel is achieved by means of @entity5274 . Pharmacological relaxation of the intestine decreases motion artifact. Intraluminal contrast media consist of either hyperdense, "positive" or @entity6152 , "negative" liquids. RESULTS: Thin-slice MSCT of the entire abdomen allows high-quality post processing (MPR, thin-slice @entity11542 ). Due to superior distension, Sellink CT improves estimation of @entity850 or changes in thickness and contrast of bowel wall. Positive contrast is superior in the detection and preoperative localization of abscess, @entity292 or @entity5 , because it accurately differentiates between intra- and extraluminal structures.However, negative contrast facilitates quantitative evaluation of bowel wall thickening or enhancement and demonstrates @entity360 . CONCLUSION: MSCT of the small intestine is superior to conventional enteroclysis, especially in the diagnosis of mesenterial or other @entity66 . As a side effect, the colon is assessed in the same examination. Radiation dose is less in MSCT (7.8-13.3 @entity2073 ) than in conventional fluoroscopy (13.99+/-7.57 @entity2073 ). MSCT can be performed as an alternative or adjunct to colonoscopy, if endoscopic access is restricted. It is already the imaging modality of choice in acute @entity4436 .
