CT Enterography

CT enterography is a non-invasive technique used for diagnosis of small bowel disorders such as Crohn’s disease, suspected Meckel’s diverticulum and small bowel obstruction by oral administration of neutral contrast medium. This procedure is mainly done to evaluate small bowel features by the administration of Mannitol/Neutral contrast medium. Patient undergoing enterography is asked to withhold for 4 hours prior the examination and is asked to drink 1litre of water that has been previously prepared with Mannitol –neutral contrast medium.  Helical scanning is done from the diaphragm and symphysis pubis. Multi planar reformatting of axial image data allows excellent characterization of enteric and extra enteric abnormality. CT enterography is particularly useful for differentiating between active and fibrotic bowel stricture in patients in Crohn’s disease, thus enabling selection of most appropriate treatment (medical management or intervention) for an improved outcome. CT enterography allows excellent visualization of the entire thickness of bowel wall and depicts extra enteric involvement as well, providing more detailed and comprehensive information about the extent and severity of the disease process.
