【摘要】 目的探讨MRI对十二指肠乳头癌的诊断价值。方法回顾性分析经病理组织学检查证实的22例十二指肠乳头癌的MRI及MRCP表现,包括肠乳头区病灶、胰胆管扩张、胆管梗阻等改变。结果MRI显示22例中十二指肠乳头部肿块14例、十二指肠肠壁增厚8例;MRCP见肝内外胆管中重度扩张14例,轻度扩张6例,无扩张2例;梗阻端呈截断中断改变12例,"鸟嘴状"狭窄4例,未见明显梗阻6例。结论MRI结合MRCP是诊断十二指肠乳头癌的一种敏感且无创伤性的检查方法。更多还原

【Abstract】 Objective To evaluate the value of MRI & MRCP in diagnosis of duodenal papillary carcinoma.Methods MRI and MRCP findings of duodenal papillary carcinoma in 22 cases proved by pathology were retrospectively analyzed,including the changes of the duodenum,the dilation of pancreaticobiliary duct and the obstruction of bile duct.Results On MRI,duodenal papillary masses in 14/22 cases and thickening wall of duodenum in 8 cases were showed.MRCP images showed heavy dilatation of the biliary ducts in 14 cases,light dilatation in 6 cases and 2 were normal;the end of the dilated bile ducts was as "cut-off" sign in 12 cases,as "bill"sign in 4 cases.Conclusion MRI combined with MRCP is a sensitive and noninvasive method in diagnosis of duodenal papillary carcinoma.更多还原
