【摘要】 目的:评价多层螺旋CT动态增强扫描对肝门区胆管癌的诊断价值。方法:17例肝门胆管癌行螺旋CT平扫及动态增强扫描,并与手术及病理对照分析。结果:15例平扫表现为肝门区低密度软组织肿块,2例表现为肝门区胆管不规则增厚,管腔狭窄。增强扫描17例均有延迟强化。结论:多层螺旋CT动态增强扫描对肝门胆管癌的诊断具有重要意义。更多还原

【Abstract】 Objective:To assess the value of spiral MSCT in the diagnosis of hilar cholangiocarcinoma.Methods:17 patients of hilar cholangiocarcinoma underwent CT plain and dynamic enhanced scan.CT findings were analysed in comparison with that of surgery and pathology.Results:On plain scan,the lesions appeared as soft tissue mass with low density in hepatic hilar(n=11),bile duct wall irregularly thickened and bile duct narrowed(n=2).On dynamic enhanced scan,delayed enhancement was seen in 17 cases.Conclusion:Plain spiral CT and dynamic enhanced scan have great value in showing the morphological features and improving the diagnosis of hilar cholangiocarcinoma.更多还原
