The Liver Imaging Reporting and Data System (LI-RADS) was developed to standardize the interpretation and reporting of liver observations in at-risk populations, aiding in the diagnosis of hepatocellular carcinoma (HCC). Despite its advantages, the application of LI-RADS can be challenging due to the complexity of liver pathology and imaging interpretation. This comprehensive review highlights common pitfalls encountered in LI-RADS application and offers practical strategies to enhance diagnostic accuracy and consistency among radiologists. Key areas of difficulty include misapplication in non-high-risk populations, misinterpretation of major imaging features such as arterial phase hyperenhancement and washout, and incorrect application of ancillary features. Additionally, the review addresses challenges related to atypical HCC presentations and HCC mimics. By recognizing and addressing these pitfalls, radiologists can improve diagnostic accuracy and avoid common mistakes in the diagnosis of HCC.
肝脏影像报告和数据系统（LI-RADS）的开发旨在规范对高危人群肝脏观察结果的解读和报告，辅助肝细胞癌（HCC）的诊断。尽管具有诸多优势，但由于肝脏病理学和影像解读的复杂性，LI-RADS的应用可能具有挑战性。本综述强调了LI-RADS应用中常见的陷阱，并提供了实用策略，以提高放射科医生之间的诊断准确性和一致性。主要困难领域包括在非高危人群中的错误应用、对动脉期高增强和廓清等主要影像特征的错误解读以及辅助特征的错误应用。此外，该综述还探讨了与非典型HCC表现和HCC模仿物相关的挑战。通过认识并解决这些陷阱，放射科医生可以提高诊断准确性，避免在HCC诊断中出现常见错误。
