Biliary complications are the most common complications after liver transplantation. Computed tomography (CT) and magnetic resonance imaging (MRI) are cornerstones for timely diagnosis of biliary complications after liver transplantation. The diagnosis of these complications by CT and MRI requires expertise, mainly with respect to identifying subtle early signs to avoid missed or incorrect diagnoses. For example, biliary strictures may be misdiagnosed on MRI due to size mismatch of the common ducts of the donor and recipient, postoperative edema, pneumobilia, or susceptibility artifacts caused by surgical clips. Proper and prompt diagnosis of biliary complications after transplantation allows the timely initiation of appropriate management. The aim of this pictorial review is to illustrate various CT and MRI findings related to biliary complications after liver transplantation, based on time of presentation after surgery and frequency of occurrence.
胆道并发症是肝移植术后最常见的并发症。计算机断层扫描（CT）和磁共振成像（MRI）是及时诊断肝移植术后胆道并发症的基石。通过 CT 和 MRI 诊断这些并发症需要专业知识，主要是识别细微的早期迹象，以避免漏诊或误诊。例如，由于供体和受体的胆总管大小不匹配、术后水肿、气胆或手术夹引起的磁化率伪影，MRI 可能会误诊胆管狭窄。及时正确诊断肝移植术后胆道并发症可及时启动适当的治疗。本影像学综述的目的是根据术后出现的时间和发生的频率，说明与肝移植后胆道并发症相关的各种 CT 和 MRI 表现。
