Magnetic resonance imaging is routinely used for the workup of patients with focal or diffuse liver disease, including primary hepatocellular lesions, storage diseases, metastatic liver disease, and diseases of the hepatobiliary tree. The most important magnetic resonance imaging sequences used for diagnostic imaging of the liver consist of T1-weighted sequences, T2-weighted sequences, and at least the arterial and delayed phases of dynamic gadolinium-enhanced imaging. This article provides an overview of magnetic resonance imaging of primary hepatocellular lesions and will describe the following: (1) the classification and etiology of primary hepatocellular lesions, including focal nodular hyperplasia, hepatocellular adenoma, and hepatocellular carcinoma; (2) the stepwise carcinogenesis of hepatocellular carcinoma in cirrhosis on magnetic resonance imaging; and (3) the typical imaging findings of primary hepatocellular lesions on magnetic resonance imaging, with differential diagnoses.
磁共振成像常用于对患有局灶性或弥漫性肝病的患者进行检查，包括原发性肝细胞病变、贮积病、转移性肝病以及肝胆系统疾病。用于肝脏诊断成像的最重要的磁共振成像序列包括T1加权序列、T2加权序列以及至少动态钆增强成像的动脉期和延迟期。本文概述了原发性肝细胞病变的磁共振成像，并将描述以下内容：（1）原发性肝细胞病变的分类和病因，包括局灶性结节性增生、肝细胞腺瘤和肝细胞癌；（2）肝硬化中肝细胞癌在磁共振成像上的逐步致癌过程；（3）原发性肝细胞病变在磁共振成像上的典型影像学表现及鉴别诊断。
