摘　　要：目的:探讨磁共振成像仪检查在肝移植术后并发症诊断中的优势。方法:回顾性分析78例肝移植术后发生并发症患者的MRI资料,结果经手术、肝组织活检或血管、胆道造影证实。结果:64例患者术后均有皮肤、巩膜黄染、发热、腹痛等症状,实验室检查发现肝功能异常。14例患者无临床症状,肝功能正常。影像分析明确发现门脉主干吻合口狭窄21例;肝动脉狭窄10例;下腔静脉吻合口狭窄1例;胆管吻合口狭窄15例;肝门水平非吻合口狭窄5例;移植排异反应17例;肝癌复发9例。结论:磁共振成像仪检查能清晰显示手术血管、胆管的狭窄、扩张,是评价肝移植术后并发症较好的检查设备。Objective To study the advantage of magnetic resonance imaging（MRI） in diagnosis of complications following liver transplantation. Methods The MRI appearances were analyzed retrospectively in seventy-eight patients with postoperative complications after liver transplantation which was confirmed by operation, hepatic biopsy, angiography and cholangiography. Results The symptoms of skin and sclera jaundice, fever and belly pain were found in sixty-four patients. Liver function was abnormal in laboratory tests. Fourteen were non-symptom with normal liver function. By analyzing the MRI images, the results were found including hepatic portal vein anastomosis stenosis（n=21）, hepatic arterial anastomosis stenosis（n =10）, inferior vena cava anastomosis stenosis（n =1）, bile duct anastomosis stenosis（n =15）, bile duct non- anastomosis stenosis（n=5）, transplant rejection（n=17）, hepatic carcinoma recurrence（n=9）. Conclusion MRI can be revealed hepatic vessels and bile ducts stenosis and dilations; it＇s the best device in diagnosis of complications after liver transplantation.
