目的 探讨CT增强扫描与MRCP在 肝内胆管癌诊断中的应用价值差异。方 法 回顾性分析2014年1月到2015年12月 的63例经手术病理证实的肝内胆管癌患者 的增强CT扫描、MRCP平扫资料，比较分析 增强CT和MRCP的诊断结果。结果 本组研 究肝内胆管癌患者63例，经增强CT诊断， 确诊48例，增强CT对肝内胆管癌的确诊率 达76.2%；经MRCP诊断，确诊55例，MRCP 对肝内胆管癌的确诊率高达87.3%。由此 可见MRCP的诊断准确率显著高于增强CT诊 断，此差异具有统计学意义(P＜0.05)。 结论 MRCP在肝内胆管癌诊断中比增强CT 更具有优势，临床诊断中可联合应用两种 方法对肝内胆管癌进行诊断。

Objective To explore the value of enhanced CT and MRCP in the diagnosis of intrahepatic cholangiocarcinomas. Methods The data of enhanced CT and MRCP in 63 patients with intrahepatic cholangiocarcinomas confirmed by operation and pathology from 2014 to 2015 were analyzed retrospectively. The diagnostic results of enhanced CT and MRCP were compared and analyzed. Results 63 cases of this group of patients with intrahepatic cholangiocarcinomas, by enhanced CT diagnosis, diagnosed in 48 cases, diagnosis rate was 76.2%, the MRCP diagnosis of 63 cases, MRCP on intrahepatic cholangiocarcinomas diagnosis rate up to 87.3%. Thus the diagnostic accuracy of magnetic resonance imaging was significantly higher than that of enhanced CT diagnosis, the difference between the two groups was statistically significant. Conclusion MRCP is superior to enhanced CT in diagnosis of intrahepatic cholangiocarcinomas, but we can diagnosos intrahepatic cholangiocarcinomas by the combination of two methods in clinic.
