The Liver Imaging Reporting and Data System (LI-RADS) is a widespread comprehensive system for standardising the reporting and data collection of liver imaging to standardise chronic liver disease evaluation. However, the LI-RADS, based on the identification of some categories of lesions by means of a conceptual and nonquantitative probability approach, has many limitations. In fact, recently, the European Association for the Study of the Liver Guidelines regarding the management of hepatocellular carcinoma did not accept the LI-RADS. The aim of this paper was to critically analyse the LI-RADS, focusing on some interesting issues such as the absence of a clear distinction between two different imaging modalities (computed tomography and MRI), the lack of validation of some major features, the assessment of its ancillary features and its complexity. Despite these limitations, the LI-RADS represents a great opportunity for the radiological community. We must not let it escape, but time and experience are necessary for its improvement.
肝脏影像报告和数据系统（LI-RADS）是一个广泛应用的综合系统，用于规范肝脏影像的报告和数据收集，以标准化慢性肝病评估。然而，LI-RADS基于通过概念性和非定量概率方法识别某些类别的病变，存在许多局限性。事实上，最近欧洲肝脏研究协会关于肝细胞癌管理的指南并未采纳LI-RADS。本文的目的是对LI-RADS进行批判性分析，重点关注一些有趣的问题，如两种不同成像方式（计算机断层扫描和磁共振成像）之间缺乏明确区分、一些主要特征缺乏验证、其辅助特征的评估及其复杂性。尽管存在这些局限性，LI-RADS对放射学界来说仍是一个巨大的机遇。我们绝不能错失，但改进它需要时间和经验。
