原位肝移植前后胆道及血管的磁共振成像评估

MRI evaluation of vascular and biliary complications before and after orthotopic liver transplantation

背景：磁共振成像扫描技术的完善,实现了＂一站式＂磁共振综合检查,即1次检查过程中运用多种序列,同时对肝脏血管、胰胆管系统及上腹部器官进行影像评估,方便、快速、简捷。目的：评价磁共振成像检查在肝移植前后的应用价值。方法：选择中南大学湘雅三医院移植中心收治的肝硬化及肝癌患者38例,男27例,女11例,年龄23-68岁。原位肝移植前后进行磁共振成像检查,同时行双排螺旋CT检查,比较两种方法的优劣,最后以手术、病理检查结果确认。结果与结论：所有终末期肝脏疾病患者原位肝移植前后经磁共振成像检查,能较准确地描述出肝癌病灶的情况,血管及胆道系统的异常解剖形态及其内栓子和结石的情况,其结果明显优于双排螺旋CT检查。说明磁共振成像在肝移植前评估和移植后并发症早期发现中有非常重要的作用。

BACKGROUND：MRI scanning technology have been improved and achieved a ＂one-stop＂ MR comprehensive examination, that is, an inspection process using a variety of sequences to get the image assessment of liver blood vessels, pancreatic duct system and abdominal organs. It is characterized by convenient, fast and simple. OBJECTIVE：To evaluate the MRI examination before and after liver transplantation in clinical application.METHODS：Totally 38 patients with liver cirrhosis and liver cancer received treatment in Transplantation Center, the Third Xiangya Hospital, Central South University, were selected, including 27 males and 11 females, aged 23-68 years. They underwent 1.5T MRI and 2-slice spiral CT inspections pre-and post-orthotopic liver transplantation, and finally be confirmed by surgical and pathological findings. The observation effects were compared with two scanning methods. RESULTS AND CONCLUSION：All patients with end-stage liver disease examined by pre-and post-MRI can accurately describe the case of liver lesions, abnormal blood vessels and biliary tract anatomy, as well as emboli and stones.The result is better than 2-slice spiral CT. That MRI assessment has a very important value in evaluation pre-orthotopic liver transplantation and early detection of complications after transplantation.
