LI-RADS 4 - probably HCC. Of all LR-4 observations about 74% are HCC and 81% are malignant . The categorizing of an observation as LR-4 depends on the size of the lesion, the presence of APHE and the amount of additional major features (see LIRADS table).

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 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) .

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, ...

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 …

2024年8月28日 · LI-RADS define an "observation" as a distinctive area compared to background liver. Focal abnormalities are not referred to as lesions or nodules. If an observation has been biopsied and the diagnosis is certain, then the pathological diagnosis should be reported, rather than the CEUS LI-RADS category.

2017年9月18日 · The Liver Imaging–Reporting and Data System (LI-RADS) is a comprehensive system for standardized interpretation and reporting of computed tomography and magnetic resonance examinations performed in patients at risk for hepatocellular carcinoma.

Introduction and objectives: The liver imaging reporting data system (LI-RADS) for hepatocellular carcinoma (HCC) was proposed to standardize and enhance consensus of reporting. However, clinical utility of LI-RADS has not been evaluated in Latin America.
