Objective: To investigate the diagnostic value of Vater’s ampullary carcinoma in CT. METHODS: We retrospectively analyzed 26 Vater’s ampullary carcinomas which were confirmed by pathology and CT data from 1990 to 1997 in this hospital. Results: Duodenal descending cavity filled defect, intraluminal soft tissue mass, ampullary common bile duct truncation and intrahepatic bile duct, high dilation, common bile duct dilatation, gallbladder enlargement, “double tube sign” is pot Direct and indirect CT signs of abdominal cancer. The display of these signs is related to scanning techniques and equipment. The diagnostic accuracy rate in this group was 84.6%. Conclusion: CT diagnosis of ampullary carcinoma is an effective and accurate examination method. CT insensitivity to uncinate process, early duodenal invasion, and local lymph node detection
