摘要: 目的 探讨64排螺旋CT三期增强扫描和三维重建在肝外胆管癌中的诊断价值。方法 对20例经手术病理或活检证实的肝外胆管癌患者,分别行动脉期、门脉期和延迟期扫描及重建薄层图像。结果 11例肝门部胆管癌位于左肝管3 例、右肝管2例,肝总管端6例。11例均有肝内胆管呈蟹足状,藤状改变。肝门区均见软组织肿块影。增强早期肿块强化不明显,肿块内呈低密度影3例。延迟扫描胆管癌肿块全部强化者9例,呈不均匀强化者2例;9例胆总管癌均显示扩张胆总管突然中断或变形,其中4例管壁可见环形不均匀增厚,管腔狭窄,2例腔内见结节状软组织影,2例腹膜后见肿大淋巴结。结论 64排螺旋CT三期增强扫描及三维重建是诊断肝外胆管癌的理想检查手段。

Abstract: Objective To explore the application of three enhanced scanning and three-dimensional reconstruction of 64-slice spiral CT in the diagnosis of extrahepatic bile duct carcinoma.Methods 20 patients with surgically and pathologically proved extrahepatic bile duct carcinoma were examined by 64-slice spiral CT.Results Out of 11 patients with hilar cholangiocarcinoma,the tumors located in the left hepatic duct in 3,in right hepatic duct in 2 and in hepatic duct terminal in 6 cases;Intrahepatic bile ducts were dilated in 11 cases with hilar cholangiocarcinoma;mass enhancement was not obvious in early phase;in delayed phase,9 cases showed complete enhancement,and heterogeneous enhancement in 2 cases;Dilated common bile duct was suddenly interrupted or deformed in 9 cases with cholangiocarcinoma of common bile duct;Intraductal soft tissue node was shown in 2 cases.Conclusion 64-slice spiral CT is an ideal Methods to diagnose the extrahepatic bile duct carcinoma.
