Hepatic lesions with delayed enhancement are sometimes encountered on gadolinium-enhanced MRI of the liver. This study illustrates the varied appearances of several pathologic entities with delayed enhancement, including hepatic hemangioma, hepatic metastases, intrahepatic cholangiocarcinoma, focal nodular hyperplasia, hepatic abscess, hepatocellular carcinoma, and hepatocellular carcinoma after transcatheter arterial chemoembolization, and presents the utility of arterial-phase dynamic MRI in the differential diagnosis of these lesions. Possible causes of these delayed enhancements are also discussed.
肝脏钆增强磁共振成像（MRI）有时会发现有延迟强化的肝脏病变。本研究阐述了几种具有延迟强化的病理实体的不同表现，包括肝血管瘤、肝转移瘤、肝内胆管癌、局灶性结节性增生、肝脓肿、肝细胞癌以及经导管动脉化疗栓塞术后的肝细胞癌，并介绍了动脉期动态MRI在这些病变鉴别诊断中的作用。还讨论了这些延迟强化的可能原因。
