摘　　要：目的:探讨MRI(包括平扫、动态增强、MRCP和3D DCE-MRA)对肝门区肿瘤的诊断及术前评估的价值。方法:回顾性分析60例肝门区肿瘤的MR表现,其中肝细胞癌(HCC)8例,胆管癌(HC)30例,转移性病变18例,血管瘤4例,并与手术或病理结果对照。结果:MRCP对肝门部胆管梗阻水平定位准确率达93.3%(56/60),平扫联合动态增强对病变定性诊断准确率为81.7%(49/60)。3D DCE-MRA显示病变供血动脉1例、动静脉瘘1例、肝动脉受累1例、门静脉瘤栓2例、门静脉受浸润9例,门静脉受推移3例、下腔静脉受累2例。结论:MRI一系列检查方法对肝门区肿瘤定性诊断及外科手术方案制订具有重要意义。Objective：To investigate the value of the MR scanning in the diagnosis of hepatic hilar carcinoma and clinical application. Methods：The appearances of MRI in 60 cases of hepatic hilar carcinoma were retrospectively analyzed,including hepatocellular carcinoma （HCC, n= 8）, hilar cholangiocarcinoma （ HC, n= 30）, hilar metastasis （n= 18）, and hemangioma （n=4）. MRI appearances were correlated with the results of pathology or surgery. Results： MRCP could confirm the level of bile duct obstruction with accuracy of 93.3%. The accuracy of precontrast with dynamic contrast-enhanced MR scanning in characterization of the lesion of all cases was 81.7%. On 3D DCE- MRA,tumor feeding artery was shown in 1 case,arteriovenous fistula （AVF） was shown in 2 cases,involvement of hepatic artery was shown in 1 case, tumor thrombosis of portal vein was shown in 2 cases,invasion of portal vein was shown in 9 cases, compression and displacement of portal vein were shown in 3 cases, and IVC was involved in 2 cases. Conclusion： MRI is important for characterization and preoperative evaluation of hepatic hilar carcinoma.
