[摘要] 目的 总结多层螺旋CT血管成像技术在肝门部胆管癌术前评估中的应用体会。 方法 对2007～2008年7例肝门部胆管癌患者术前行多层螺旋CT检查并行肝动脉及门静脉CT成像。成像方法包括多层面重建(MPR)、最大密度投影(MIP)、曲面重建(CPR)、容积再现(VR)、表面遮盖成像(SSD)，并与手术探查结果对比。 结果 全部患者血管成像均一次顺利完成检查，清晰显示血管分支、走行及周围结构的关系，与手术结果基本一致。 结论 多层螺旋CT血管成像多种后处理方法的综合应用有利于全面显示肝门胆管癌与周围血管的关系，对手术方式及可切除性有一定应用价值。

[Abstract]Objective To summarize multislice CT angiography imaging technology in liver door department cholangiocarcinoma preoperative assessment of the application experience. Methods From 2007 to 2008 year, 7 cases liver bile duct cancer door preoperative line MDCT check hepatic artery and portal vein parallel CT imaging. Imaging methods including many levels(MPR), largest reconstruction density projection(MIP), surface reconstruction(CPR), volume representation(VR), surface cover imaging(SSD), and the results were compared with surgical exploration. Results All patients vascular imaging procedure was completed inspection, clear display vascular branches, direction and surrounding structure, the relation between the and surgical results are basically the same. Conclusion Multislice CT angiography imaging post-processing method to display the integrated application of comprehensive liver bile duct carcinoma and peripheral vascular door in relation to the operation method and the resectable sex have certain application value.

肝门部胆管癌是指位于胆囊管开口以上胆管(包括肝总管、左右肝管汇合部和左右肝管)的黏膜上皮癌，约占肝外胆管癌的58%～75%[1]。肝门部解剖关系复杂，胆管、肝动脉、门静脉紧密毗邻，肝门部胆管癌具有沿淋巴管、神经、血管转移的生物学特性，故肝动脉、门静脉易受肿瘤侵犯，胆管及血管侵犯情况是决定肝门部胆管癌能否切除的最主要因素。多层螺旋CT血管成像正越来越广泛地应用于血管及血管相关性病变的诊断。作者应用多层螺旋CT血管成像技术对我院7例肝门部胆管癌患者术前进行检查，总结多层螺旋CT血管成像技术在肝门部胆管癌术前评估中的应用价值。
