  1. CEUS contrast-enhanced ultrasound, CECT contrast-enhanced computed tomography, AUC area under the curve, CI confidence interval
  2. aThe discrimination of AUC value was considered fair (AUC < 0.6), moderate (AUC, 0.6-0.75), and substantial (AUC > 0.75), respectively
  3. #p value was obtained from the comparison between the CEUS-predominant and CECT-predominant models by the McNemar test. p < 0.05 was considered to indicate a statistical difference
