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).

LI-RADS® was created to standardize the reporting and data collection of CT and MR imaging for hepatocellular carcinoma. This method of categorizing liver findings for patients with risk factors for developing HCC allows the radiology community to: Apply consistent terminology. Reduce imaging interpretation variability and errors.

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).

LI-RADS is a common language developed by experts in liver imaging and liver disease to report findings on your scan. It helps eliminate mistakes and improve communication between members of your care team.

The Liver Imaging Reporting and Data System (aka LI-RADS) is a quality assurance tool created and trademarked by the American College of Radiology in 2011 to standardize the reporting and data collection of CT and MR imaging patients at risk for hepatocellular carcinoma (HCC), or primary cancer of the liver cells.

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 …

The Liver Imaging Reporting and Data System (LI-RADS) standardizes the interpretation and reporting of imaging examinations in patients at risk for hepatocellular carcinoma (HCC). For focal liver observations it assigns categories (LR-1 to 5, LR-M, ...

2021年6月2日 · L4*/L5: enhancing capsule is L4. Non-peripheral washout or threshold growth is L5. 从良性病变到增生性结节到HCC不等。 许多LR-3是血管假性病变（异常灌注）。 在所有LR-3病变中，约37％为HCC，39％为恶性。 结节灶，具有FNH或肝腺瘤表现。 ＜20mm的结节，无主要特征，但有一个或多个恶性肿瘤的辅助表现，如病变内脂肪、T2高信号，弥散受限、肝胆特异期低信号。 结节≥20mm，无主要或辅助特征。 感谢大家对熊猫的关注和支持！ 你的阅读就是知 …

LI-RADS definitions were applied to magnetic resonance images (MRI) or computed tomography (CT) abdominal scans at time of listing and at final pre-LT reassessment and compared to explant pathology findings; specifically, major nodule (NOD1).
