Advances in organ procurement and surgical techniques have made orthotopic liver transplantation (OLT) an accepted treatment for many adult patients with end-stage hepatic disease. At present, OLT is being performed in patients with a variety of diseases, and 5-year survival is estimated at 65-78% [1]. Over 80% of hepatic transplants are performed in patients with cirrhosis or primary cholestatic liver disease, and only 5% of transplants are performed for malignant hepatic neoplasms (Table 1) [2]. Because the supply of donor organs is limited, preoperative clinical and radiologic evaluation of the transplant candidate is critical for appropriate patient selection. The main objective of preoperative imaging is to provide the surgeon with the pertinent information needed to plan and perform OLT and to exclude patients for whom surgery either is not feasible or will be of no benefit.
器官获取和外科技术的进步使原位肝移植（OLT）成为许多终末期肝病成年患者可接受的治疗方法。目前，OLT正在多种疾病患者中进行，估计5年生存率为65% - 78%[1]。超过80%的肝移植手术是在肝硬化或原发性胆汁性肝病患者中进行的，而仅5%的移植手术是针对恶性肝肿瘤进行的（表1）[2]。由于供体器官供应有限，对移植候选人进行术前临床和影像学评估对于恰当选择患者至关重要。术前影像学检查的主要目的是为外科医生提供计划和实施OLT所需的相关信息，并排除那些手术不可行或无益处的患者。
