role of multislice CT in evaluation of chronic inflammatory bowel disease

Ulcerative colitis [UC] and Crohn's disease [CD] are the two main subtypes of chronic inflammatory bowel diseases [IBD]. Multidetector computed tomography [CT] has been recognized as a promising modality for the evaluation of Crohn's disease and other small-bowel abnormalities. CT enterography differs from routine abdominal CT in that CT enterography uses multidetector CT. [narrow section thickness and reconstruction interval], intravenous contrast material, and large volumes of a neutral oral contrast agent to improve depiction of the small-bowel wall and lumen. In patients with Crohn's disease, CT enterography is increasingly used to detect enteric inflammation in addition to extra-enteric complications. The aim of the work will be directed to identify the role of MSCT in the evaluation of idiopathic inflammatory bowel diseases. The present work included 30 patients suffering from idiopathic inflammatory bowel disease [ulcerative colitis or Crohn's disease. All patients subjected to CT enterography and/or colonography using multi-detector row CT and iso-osmotic mannitol as neutral enteric contrast material and Ileo-colonoscopy and mucosal biopsy. CT findings include abnormal wall thickening [generally 1 cm] with skip areas of colonic stenosis and dilatation. Associated findings include pericolonic fat stranding, fistulas, abscesses, fibro fatty proliferation, and mesenteric adenopathy. Findings such as mural thickening, mural enhancement, increased attenuation of the perienteric fat, and the Comb sign have been reported to indicate active inflammatory Crohn's disease. MSCT is a great diagnostic tool in detecting and assessing early changes of inflammatory bowel disease as well as monitoring the disease progress and evaluating the complication

Role of 64 MSCT in the evaluation of aortic lesions

Multslice CT [MSCT] has proved its importance and applicability in the evaluation of vascular disease including stenosis, occlusion, aneursyms and dissection as well as evaluation of post-traumatic events. The aim of the work will be directed to identify the role of MSCT in the evaluation of aortic lesions. The study will be conducted on patients suspected of having aortic lesions based on clinico- laboratory basis. Each patient will be subjected to thorough history taking, Clinical examination, and MSCT aortography. The advance of cardio-thoracic surgery techniques adds the burden of many questions that need to be answered including the extent, width, and shape of the flap and implication of the coronary arteries and major aortic branches. The presence of leakage is of equal importance in both dissecting and atherosclerotic aneurysms. Evaluation of abdominal aortic aneurysm and leakage by MSCT has proved its usefulness particularly in planning for operative intervention including the length, size of the aneurysm and implication of the major aortic branches. 64 MSCT is an excellent tool for examining the aorta. It gives a great deal of information that, abolishes the need of another diagnostic tool prior to operative intervention. It offers a great mapping of dissecting aortic flap, abdominal aortic aneurysms and coarctation. Time of an essence in dealing with emergency patients and 64 MSCT offers a great portal of diagnosis considering time efficacy and accuracy
