MRI及MRCP评估肝门部胆管癌可切除性应用价值研究

目的研究肝门部胆管癌的影像学表现,探讨增强MRI及磁共振胆胰管成像(MRCP)对肝门部胆管癌可切除性评估价值。方法回顾性分析2006年6月至2009年10月间广州军区广州总医院经病理证实的30例肝门部胆管癌MRI增强扫描、MRCP表现,将MRI术前可切除性评估与手术结果进行比较。结果 30例肝门部胆管癌均显示肝门部肿块,增强以延迟强化为主,肝内胆管不同程度扩张;MRI增强扫描结合MRCP可有效显示胆管受侵范围、门静脉血管受侵情况、肝实质及淋巴结有无转移。MRI综合评价肿瘤可切除的敏感性、特异性及准确性分别为81.8%、91.6%及86.9%。结论增强MRI结合MRCP,能在术前较为客观地对肝门部胆管癌的可切除性进行评价。

Preoperative evaluation of hepatic hilum cholangiocarcinoma resectability with enhanced MRI and MRCP

Objective To study enhanced MRI and MRCP findings of hepatic hilum cholangiocarcinoma and their preoperative evaluation value. Methods Enhanced MRI and MRCP findings in 30 patients with hepatic hilum cholangiocarcinoma proved pathologically between June 2006 and October 2009 at General Hospital of Guangzhou Military Command of PLA were analyzed retrospectively. The preoperative evaluations and operative results were compared. Results All patients were found to have soft tissue mass at porta hepatis with del...
