Because of an overwhelming demand for cadaveric livers in the United States that far outstrips supply, living related liver transplantation is increasingly being performed to help treat a cohort of patients with severe end-stage liver disease. This procedure demands careful preoperative evaluation to minimize morbidity to the healthy donor and recipient, however. As a part of the workup, radiologic assessment of the donor hepatic vascular and biliary anatomy, hepatic volume, and hepatic parenchyma (with regard to focal and diffuse liver disease) is essential. In this pictorial essay, the experience of a group of investigators at the University of California at Los Angeles is reviewed, and the essential radiologic components of the preoperative evaluation of hepatic vascular and biliary anatomy, hepatic parenchyma, and lobar volume are described. The roles of high-field magnetic resonance (MR) imaging, MR angiography, MR cholangiopancreatography, multidetector-row computed tomography (CT) angiography, and CT cholangiography in the workup are discussed.
由于美国对尸体肝脏的需求远远超过供应，亲属活体肝移植越来越多地用于治疗一批严重终末期肝病患者。然而，该手术需要仔细的术前评估，以尽量减少对健康供体和受体的发病率。作为检查的一部分，对供体肝血管和胆管解剖结构、肝体积和肝实质（针对局灶性和弥漫性肝病）进行放射学评估至关重要。在这篇图文并茂的文章中，回顾了加利福尼亚大学洛杉矶分校一组研究人员的经验，并描述了肝血管和胆管解剖结构、肝实质和叶体积术前评估的基本放射学组成部分。讨论了高场磁共振（MR）成像、MR血管造影、MR胰胆管造影、多排螺旋计算机断层扫描（CT）血管造影和CT胆管造影在检查中的作用。
