摘　　要：目的:探讨MRCP及MRI联合应用对壶腹癌的诊断和鉴别诊断价值,通过与手术病理对照分析,进一步提高MRI对壶腹癌诊断的准确性。方法:回顾性分析笔者所在医院经手术病理或十二指肠镜活检证实的25例壶腹癌MRCP及MRI影像学资料。结果:25例壶腹癌中,术前有22例经MRI准确诊出。25例中表现为十二指肠乳头区肿块的18例(81.8%),其中,肝内外胆管软藤样扩张14例,双管征17例,胆囊体积增大14例,胆总管腔截断征12例。余7例中,4例MRCP表现为:胆总管末端呈漏斗征4例,胰管轻度扩张3例,3例十二指肠壁不规则增厚。另有3例术前未能准确诊断。结论:MRCP结合MRI对壶腹癌有较高的诊断价值。Objective：To explore the value of MRCP combined with MRI in the diagnosis and differential diagnosis of ampullary carcinoma.Compared with the results of surgical pathology in order to improve the accurate diagnosis of ampullary carcinoma by MRI.Methods：MRCP and MRI findings of 25 cases of ampullary carcinoma confirmed by pathology or duodenal biopsy in the authors’hospital were analysed retrospectively.Results：Before surgery in 25 cases of ampullary carcinoma,22 cases of quasi-diagnosed by magnetic resonance.25 cases of ampullary carcinoma manifested as 18 cases of duodenal area（81.8%）,14 cases showed intrahepatic and extrahepatic bile vine-like expansion,18 cases showed the double duct sign.17 cases showed gallbladder volume increased,12 cases showed common bile duct cavity truncated levy.MRCP findings of the 4 cases in remaining 7 cases：the common bile duct end of the funnel sign in 4 cases,3 cases of mild pancreatic duct expansion,3 cases of irregular thickening of the duodenal wall.Another 3 cases failed to diagnose accurately.Conclusion：MRCP with MRI have a high diagnostic value in the diagnosis of ampullary carcinoma.
