MDCT of the Duodenum: Technique and Clinical Applications

Abstract

Computed Tomography (CT) is useful for evaluation of both benign and malignant pathology involving the duodenum. CT can detect and stage duodenal malignancies as well as detect inflammatory conditions such as duodenitis. Careful CT technique is necessary to optimize detection of abnormalities. This includes the use of oral contrast, preferably water, as well as i.v. contrast. 3D imaging can improve disease detection and help with surgical planning. This article reviews the current role of CT in duodenal imaging, describes appropriate CT protocols and illustrates a wide variety of duodenal pathology.
