摘　　要：目的研究MRI多种成像技术对肝移植术后中远期情况监测的价值。方法收集本2003年2月～2005年5月有完整临床资料的原位肝移植术后病例21例,采用的MRI技术分别为FLASHT1WI、FSET2WI、T2WI+FS、Gd-DTPA动态增强扫描、磁共振胰胆管成像(MRCP)和动态Gd-DTPA增强3DFISPMRA,分析其表现。结果21例中,胆道并发症21例,肝动脉及静脉系统并发症各8例,肝癌复发5例,移植失败4例。结论多种MRI技术联合应用,可以有效地监测肝移植术后中远期并发症情况,对指导临床治疗具有重要价值。Objective To assess the value of magnetic resonance imaging （MR J） in mid- and long-term complication monitoring after liver transplantation. Methods Twenty-one recipients receiving orthotropic liver transplantation between Feb 2003 and May 2005 were enrolled in this study. FLASH T1-weighted, T2-weighted fast spin echo, T2-weighted fat suppression, dynamic gadolinium-enhanced, MR cholangiopancreatography （MRCP） and three-dimensional dynamic gadolinium-enhanced FISP MRA images were obtained. Results Of the 21 patients, bile duct complications were detected in all cases and liver arterial and venous complications in 8 cases. Liver cancer relapse occurred in 5 cases and allograft failure in 4. Conclusion MR imaging allows effective monitoring of mid- and long-term complications of liver transplantation, which provides valuable clues for their clinical treatment.
