Summary ROC plots for univariate analyses of lesion attenuation on unenhanced images (black line, AUC = 0.839), portal venous phase contrast-enhanced images (red line, AUC = 0.577), and intermediate-delay (1–3 minute after portal venous phase) contrast-enhanced images (green line, AUC = 0.751); absolute percentage of enhancement washout (light blue line, AUC = 0.795); and relative percentage of enhancement washout (dark blue line, AUC = 0.829). Gray line is null line, depicting AUC of 0.5 (i.e., no diagnostic value).
