目的：探讨双源CT(dual-source computed tomography,DSCT)在肝外胆道梗阻疾病诊断中的价值。方法总结分析120例病理或临床治疗证实的肝外胆道梗阻疾病患者的DSCT影像资料。结果胆管结石71例，胆管炎12例，胆总管囊肿1例，十二指肠乳头区憩室1例，胆道蛔虫1例，胆管癌14例，壶腹癌3例，胆囊癌4例，胰腺癌12例。全部病例均显示肝外胆道扩张，其中78例伴肝内胆管扩张，22例呈现“双管征”。梗阻末段胆总管内可见“靶征”或“半月征”，不规则软组织影及片状、管状影，邻近胆管壁可见增厚、毛糙等；Ⅲ期强化程度不一或无强化。在肝外胆道梗阻性疾病诊断中，DSCT定位的准确率为100%，定性符合率为92.5%。结论 DSCT显示肝外胆道梗阻性病变的位置、形态、大小、密度以及相邻组织结构准确清晰，对疾病定位、定性和临床治疗的选择具有重要价值。

Objective To investigate the diagnosis value of DSCT on extrahepatic biliary obstruction. Methods Summary analysis 120 cases patients' DSCT image date proved extrahepatic biliary obstruction by pathology or clinical treatment. Result There were 71 cases of bile duct stones,12 cases of cholecystitis,1 case of choledochal cyst,1 case of duodenal diverticulum nipple,1 case of biliary ascariasis,14 cases of cholangiocarcinomas,3 cases of carcinoma of ampullas,4 cases of gallbladder carcinomas,12 cases of pancreatic carcinomas. The extrahepatic bile duct expansion was seen in all cases,78 cases with expansion of bile duct of liver inside,22 cases with double duct sign. The positioning accuracy of DSCT of extrahepatic biliary obstruction was 100%,qualitative accuracy was 92.5%. Conclusion DSCT can display the location,form,size density and adjacent tissues structure accurately and clearly. It has important value of DSCT on the localization and qualitative diagnosis of biliary obstruction and the choice of clinical treatment.
