摘　　要：目的 探讨CT对肝门部胆管癌诊断的价值。方法 回顾分析33例经病理证实的肝门部胆管癌CT平扫和增强的征像,并与手术所见对照。结果 CT表现肝内胆管扩张31例;肝门区显示肿块14例,平扫肿块密度低于肝脏密度,增强扫描肿块密度有不同程度强化,4例胆管壁呈环状不规则增厚、强化。延迟扫描5例肿块密度与肝密度相似。CT诊断定位准确率88％,定性准确率64％。结论 CT是诊断肝门部胆管癌的重要手段之一,增强延迟扫描可提高定性诊断的准确率。To study the CT diagnosis of hilar cholangiocarcinoma. Methods CT signs with and without enhancement of 33 eases with hilar cholangiolarcrnoma proved rathologically were retrospectively studied and compared with what seen in operation. Results Dilated intraheatie bile ducts were observed in 31 cases. The hilar mases are delected in 14 cases, the masses are lower attenuation on unenhanced images and are enhanced in contrast - enhanced scans; 5 of these 14 masses were iso - attenuation compared with the liver on the delayed images. CT diagnostic sensitivity and spefieity are 88% and 64% respectively. Conclusion CT scan is useful to diagnose the hilar cholangioear-cinoma delayed contrast - enhanced CT images may improve the diagnostic specificity of hilar cholangiocareioma.
