Ct Of The Duodenum

CT provides superb anatomic detail and offers a high diagnostic specificity for various gastrointestinal tract (GIT) pathological processes, as it allows direct imaging of the intestinal wall, secondary signs of bowel disease within the surrounding mesentery, and abnormal findings in adjacent structures (Freeman 2001). In clinical practice and in the radiological literature, most emphasis is placed on CT imaging of the colon, the stomach, and the distal small bowel. The current widespread use of abdominal CT, however, has also resulted in the detection of various duodenal abnormalities (Jayaraman et al. 2001; Zissin et al. 2002). This chapter reviews the CT findings of a spectrum of different common and uncommon pathological entities affecting the duodenum.
