title: Technical principles in CT evaluation of the gut.
abstract: Computed tomography (CT) of the abdomen is a sophisticated, multifaceted, and expensive test that requires meticulous attention to technique and extensive pretest planning. Evaluation of the gut is an integral part of every abdominal CT, and a successful examination requires knowledge of the characteristics of oral and intravenous contrast materials, the available technology, and the ways these factors interact and influence the quality of the images. Careful tailoring of the examination and flexibility to combine the various techniques ensures a successful CT examination not only of the gastrointestinal tract but of the entire abdomen as well.
