Arterial-Washout Temporal Profiling in CEUS LI-RADS: A Diagnostic Algorithm for Reducing Hepatocellular Carcinoma Misclassification

Key Points

• To improve the diagnostic accuracy for hepatocellular carcinoma classification using a novel algorithm.
• Used washout time and arterial phase onset thresholds for classification.
• Applied contrast-enhanced US Liver Imaging Reporting and Data System.
• Evaluated diagnostic performance of categories including LR-M and LR-5.
• Reduced misclassification of hepatocellular carcinoma as category LR-M.
• Improved diagnostic performance of LR-5 in categorizing lesions.
