LI-RADS 3 - intermediate probability. LR-3 observations vary from benign lesions to dysplastic nodules to HCC. Many LR-3s are vascular pseudolesions. Of all LR-3 lesions approximately 37% are HCC and 39% are malignant . Lesions that are placed in category LI-RADS 3 are: Nodules with features of focal nodular hyperplasia or hepatic adenoma.

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:

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 …

If you are at high risk for HCC, the radiologist reading your imaging report will use the Liver Imaging Reporting and Data System, or LI-RADS. 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.

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) .

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 …

2025年1月17日 · If there is uncertainty of an observation category, upgrade category reflecting greater suspicion (example: if unsure between US-2 or US-3, pick US-3). LI-RADS US surveillance visualization score. Assessment of technical quality of the study can be categorized as: VIS-A: no or minimal limitations

2021年6月2日 · 属于li-rads 3类的病变是： 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。

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.

2021年7月23日 · We discuss the applicability of LI-RADS and focus on the elements of a standardized LI-RADS report for liver CT and MRI. We provide guidance for describing LI-RADS observations, exemplified with two case-based reporting templates, and illustrate relevant imaging findings and components to be included when reporting specific clinical scenarios.
