摘要
目的：探讨MRI及磁共振胰胆管成像（MRCP）在高位胆道恶性梗阻疾病中的诊断价值。方法：2002年12月～2005年12月共28例肝门区恶性病变进行MR检查，MR检查包括平扫和MRCP，部分病例进行动态增强扫描，所有病例经手术病理或／和其它影像学和临床资料所证实。结果：28例肝门区恶性病变在平扫和MRCP中均可见肝门区肿块、肝内胆管扩张。动态增强扫描中肝细胞癌的强化特点基本为速升速降型；肝门部胆管癌多为缓升缓降型；而转移性肿瘤的增强特点介于二者之间。结论：MRI及MRCP作为一种无创性检查手段，对肝门区恶性病变有较高的诊断和鉴别诊断价值。
Objective：To investigate the diagnostic value of M RI and MRCP in malignant biliary obstruction in superior position. Methods： From December 2002 to December 2005,28 cases of malignant diseases in hepatic hilar region confirmed by pathology or clinical data were examined by MRI and MRCP, partly by dynamic incremental scanning. Results：In all cases, lump in hepatic hilar region and intrahepatic cholangiectasis were showed in MRI and MRCP. The Dynamic incremental imaging was rapidly increased and decreased in hepatoma, slowly increased and decreased in cholangiocarcinoma, and between above ones in metastatic carcinoma. Conclusion：MRI and MRCP plays important role in diagnosis and differential diagnosis of malignant diseases in hepatic hilar region without trauma.
