The Liver Imaging Reporting and Data System (LI-RADS) is a classification system for liver lesions which is used in patients with liver cirrhosis and chronic HBV without cirrhosis, because these patients have an increased risk of hepatocellular carcinoma (HCC).

Fat sparing in solid mass Paucity of lipid in a solid mass compared with steatotic liver or in an inner nodule relative to a steatotic outer nodule. Steatotic tissue can be recognized at gradient-echo imaging when there is signal drop on out-of-phase …

2023年3月19日 · 2016年6月24日美国放射学员发布超声造影LI-RADS（ACR CEUS LI-RADS）指南,将肝脏结节的超声造影特征将其分为5类，即CEUS LR 1类——CEUS LR 5类，另外还有LR-5V及CEUS LR-M类，其各自代表的意义及诊断标准在下文中一一详述： CEUS LR-1 类，明确良性. 1、概念：100%确定病灶为良性。 2、定义：肝内病灶具有明确良性的影像学特征或随访过程中明确发现病灶消失。 如：①单纯囊肿；②典型血管瘤；③明确的局灶性肝脏脂肪浸润；④ …

2024年7月26日 · Liver Imaging Reporting and Data System (LI-RADS) is a standardized terminology and classification system for imaging findings in liver lesions. A liver lesion's LI-RADS score indicates its relative risk for hepatocellular carcinoma (HCC).

LR-M is intended to preserve the specificity of the LI-RADS algorithm for diagnosis of HCC while not losing sensitivity for diagnosis of malignancy. The purpose of this paper is to provide a brief background on LR-M, discuss the diagnostic criteria new to v2017, special considerations for its application, and management implications.

2024年11月12日 · Current evidence suggests that the algorithm performs well in the assessment of tumor response to arterial embolic and loco-ablative therapies and fair when assessing response to radiation-based therapies, with limited data to validate the latter.

2017年6月3日 · LR-M is intended to preserve the specificity of the LI-RADS algorithm for diagnosis of HCC while not losing sensitivity for diagnosis of malignancy. The purpose of this paper is to provide a brief background on LR-M, discuss the diagnostic criteria new to v2017, special considerations for its application, and management implications.

2024年12月13日 · Initially released in 2011, liver imaging reporting and data (LI-RADS) CT/MRI diagnostic algorithm categorizes hepatic observations on an ordinal scale based on the probability of hepatocellular carcinoma, malignancy, or benignity, and guides reproducible interpretation, clear communication, and standardized terminology for liver imaging.

This application is based on the Liver Imaging Reporting and Data System (LI-RADS v2013.1) developed by the American College of Radiology (ACR) to standardize imaging reporting of hepatocellular carcinoma (HCC). The application has been adapted to categorize only observations that demonstrate arterial-phase enhancement (LR3 and above).

2024年4月27日 · CT/MRI Liver Imaging Reporting and Data System (LI-RADS) is an algorithm for diagnosing and staging hepatocellular carcinoma (HCC) (CT/MRI Diagnostic LI-RADS) or assessing the response of HCC to locoregional treatment (CT/MRI Treatment Response LI-RADS) using CT or MRI with extracellular contrast agents or …
