        • Visualization (VIS)
      • Definitions

        • Ultrasound Liver Imaging Reporting and Data System (US LI-RADS): Standardized system for imaging technique, interpretation, reporting, and data collection for screening and surveillance of US exams in patients at risk for developing hepatocellular carcinoma (HCC)
