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：

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:

LI-RADS 2 - probably benign. LR-2 observations are probably benign. Of all LR-2 lesions about 16% are HCC and 18% are malignant. Examples of LR-2 lesions are probable: Cyst; Hemangioma; Perfusion alteration (e.g., arterioportal shunt) Hepatic fat deposition/sparing; Hypertrophic pseudomass; Confluent fibrosis or focal scar

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) .

2020年6月9日 · 肝脏影像报告及数据系统（li-rads） 是一个由美国放射学院（acr）发布的肝脏影像检查规范及诊断分类系统，对肝细胞癌（hcc）高风险人群的影像检查技术、征象描述术语、诊断报告及数据收集进行了详细介绍和规范化要求。

2021年6月2日 · lr-2（可能良性）：肝硬化，肝血管瘤. lr-3（待定）：肝硬化，肝脏富血供小结节. 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。 属于li-rads 3类的病变是： 结节灶，具有fnh或肝腺瘤表现。

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, ...

LI-RADS provides a standardized lexicon, strict diagnostic criteria, an easy-to-follow diagnostic algorithm, and reporting guidelines to improve the consistency and clarity of radiologist interpretation and reporting. One benefit of LI-RADS is improved communication between radiologists and clinicians.
