[Research progress of LI-RADS categories and imaging features in predicting the prognosis of liver tumors].

The liver imaging reporting and data system (LI-RADS) is an imaging assessment system that standardizes the diagnosis of hepatocellular carcinoma (HCC), indicating the benign and malignant tumor through categories as well as major and ancillary features. The higher the LI-RADS category ranking, the higher the corresponding HCC likelihood and malignancy risk. Therefore, early diagnosis and prediction of the prognostic risk factors of liver tumors by preoperative imaging have important clinical significance for improving the survival rate and prognosis of patients. This article reviews the research progress of LI-RADS categories and related imaging features in predicting the prognosis of liver tumors.肝脏影像报告和数据管理系统（LI-RADS）是一个规范肝细胞癌（HCC）诊断的影像评估系统，可通过分类来提示良恶性肿瘤，亦可根据主要征象和辅助征象提示病变的良恶性。LI-RADS类别越高，其对应HCC的概率增加，恶性肿瘤的风险增加。术前通过影像学早期诊断和预测肝脏肿瘤的预后危险因素对提高患者的生存率和改善预后具有重要临床意义。现就LI-RADS类别及其相关影像征象在预测肝脏肿瘤预后的相关研究进展进行综述。.
