Abstract

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.

LI-RADS CT/MRI算法应用中的常见缺陷和诊断挑战：全面回顾。

肝成像报告和数据系统（LI-RADS）的开发是为了标准化高危人群的肝脏观察的解释和报告，有助于肝细胞癌（HCC）的诊断。尽管具有优势，但由于肝脏病理和影像学解释的复杂性，LI-RADS的应用可能具有挑战性。这篇全面的综述强调了LI-RADS应用中遇到的常见陷阱，并提供了实用的策略来提高放射科医生的诊断准确性和一致性。关键的困难领域包括在非高危人群中的错误应用，对主要成像特征（如动脉期高增强和冲洗）的误解，以及对辅助特征的错误应用。此外，该综述还讨论了与非典型HCC表现和HCC模拟相关的挑战。通过认识和解决这些缺陷，放射科医生可以提高诊断的准确性，避免HCC诊断中的常见错误。

期刊介绍： Abdominal Radiology seeks to meet the professional needs of the abdominal radiologist by publishing clinically pertinent original, review and practice related articles on the gastrointestinal and genitourinary tracts and abdominal interventional and radiologic procedures. Case reports are generally not accepted unless they are the first report of a new disease or condition, or part of a special solicited section. Reasons to Publish Your Article in Abdominal Radiology: · Official journal of the Society of Abdominal Radiology (SAR) · Published in Cooperation with: European Society of Gastrointestinal and Abdominal Radiology (ESGAR) European Society of Urogenital Radiology (ESUR) Asian Society of Abdominal Radiology (ASAR) · Efficient handling and Expeditious review · Author feedback is provided in a mentoring style · Global readership · Readers can earn CME credits
