【摘要】 肝癌是我国发病率较高的一种恶性肿瘤。肝脏影像报告和数据系统(LI-RADS)标准化了基于影像学的肝癌诊断。用于高危患者肝细胞癌(HCC)诊断的LI-RADS是一个动态系统，最新版更新于2018年。近年来不少学者为了能够完善LI-RADS分级进行了许多研究，由于LI-RADS系统专注于特异度，对LI-DADS-3、LI-DADS-4类别病灶敏感度较低，但同时LR-3或LR-4类别的病变在临床上的相对应的治疗策略完全不同，因此LR-3或LR-4类别的正确分配在临床上显得格外重要，本文就LR-3、LR-4的分级调整方面的研究进行综述。

    [Abstract] Liver cancer is a malignant tumor with a high incidence rate in China. LI-RADS standardizes image-based diagnosis of liver cancer. LI-RADS is a dynamic system for the diagnosis of hepatocellular carcinoma (HCC) in high-risk patients. The latest version was updated in 2018. In recent years， many scholars have carried out many researches in order to improve LI-RADS classification. Because LI-RADS system focuses on specificity and has low sensitivity to LR-3 and LR-4 lesions， but at the same time， LR-3 or LR-4 lesions have completely different clinical treatment strategies. Therefore， the correct allocation of LR-3 or LR-4 categories is particularly important in clinical practice. This article reviews the research on categories LR-3 and LR-4 classification adjustment. ......
