Note: ACC denotes accuracy, Num denotes number. HCC denotes Hepatocellular Carcinoma, ICC denotes Intrahepatic Cholangiocarcinoma, MET denotes Metastatic Cancer, FNH denotes Focal Nodular Hyperplasia, HEM denotes Hemangioma, and CYST denotes Cyst. HN denotes Henan Provincial People’s Hospital.

The numerical values in each cell represent the accuracy of classifying tumor types within the corresponding size range, are presented as percentages, and are annotated with the total number of samples. Source data are provided as a Source Data file Source_data_Table_2.xlsx.
