肝移植术前影像学检查的综合评价

Preoperative Imaging Evaluation of Donors and Recipients in Liver Transplantation

目的 综述肝脏移植术前各种影像学检查方法的综合应用价值。方法 介绍适用于肝移植术前供、受体影像学检查的各种方法。通过影像学检查评估活体供肝和受体的肝脏体积、肝实质、肝脏血管系统、胆道系统及肝外情况 ,并根据相关影像学表现 ,综合评述各种方法的优缺点。结果 传统影像学方法仍有部分应用价值 ,但断面影像学手段 (超声、CT和MRI)正在发挥着越来越重要的作用。CT检查能提供各种丰富、准确的信息 ,“一站性”MRI综合检查极具优势。结论 各种影像学检查方法都有其优势和局限。能够同时反映多种所需信息的现代影像学检查方法在肝移植术前具有较大的应用前景。

Objective To review the various imaging modalities and their appropriate applications in the preoperative evaluation of both donors and recipients in liver transplantation (LT). Methods All the relevant literatures were reviewed. Different kinds of imaging modalities have been used in potential LT donors and recipients to assess the volume, the parenchyma and the vasculature of the liver, the biliary system, and the extrahepatic region of the upper abdomen and beyond. The techniques, the imaging findings, and the merits and shortcomings of various imaging modalities were presented.Results Traditional imaging techniques are still of valuable, while CT can provide rich and accurate information. 'One-stop' comprehensive MR examination is emerging as the method of choice for the preoperative evaluation LT recipients and donors. Conclusion Each imaging method has its merits and limitations. Those imaging methods which can provide accurate and comprehensive information are likely to have better application future.
