title: Technical note: low density contrast in upper abdominal computed tomography.
abstract: We describe the use of a fat-based low density oral contrast agent in computed tomography (CT) of the upper abdomen. It has a CT number of -71 Hounsfield units (HU) and allows excellent visualization of the bowel wall and adjacent structures as well as reducing the artefacts seen with iodinated high density contrast.
