^*p value from AUC

^#p value from logistic regression

Area under the curve (AUC) values from ROC analysis and odds ratios (OR) from logistic regression analysis are shown

AUC = area under the curve; HBP = hepatobiliary phase, LAP = late arterial phase, LVP = late venous phase; NPV = negative predictive value; OR = odds ratio; PPV = positive predictive value
