Data are numbers of observations, with percentages in parentheses. CT/MRI, Computed Tomography/Magnetic Resonance Imaging; CEUS Contrast Enhanced Ultrasound; ICC, intrahepatic cholangiocarcinomas; CHC, combined hepatocellular cholangiocarcinomas; *P values were determined with McNemar test for comparison of the rate of the lesions correctly classified as LR-M category between CEUS LI-RADS and CT/MRI LI-RADS.
†kappa values were determined with Cohen k statistics for comparison of CEUS LI-RADS and MRI-LI-RADS category.
