Imaging of the liver is performed most often to detect and characterize focal liver lesions. MR imaging has been the method of choice to assess focal liver lesions accurately. Nonspecific intravenous contrast agents have been used for routine abdominal MR imaging protocols including liver imaging. Over the last 10 to 15 years new contrast agents have been developed that combine the excellent contrast resolution of MR imaging with improved tissue specificity. This article reviews various contrast agents that are in clinical use for liver MR imaging and discusses their potential clinical role.
肝脏成像最常用于检测和表征肝脏局灶性病变。磁共振成像（MR成像）一直是准确评估肝脏局灶性病变的首选方法。非特异性静脉造影剂已用于包括肝脏成像在内的常规腹部MR成像方案。在过去10到15年中，已开发出新型造影剂，将MR成像出色的对比分辨率与更高的组织特异性相结合。本文综述了目前临床用于肝脏MR成像的各种造影剂，并讨论了它们潜在的临床作用。
