  1. Note. – AUROC, area under the receiver operating characteristic curve; CI, confidence interval; L_pre and L_post refer to the mean liver HU on pre- and post-contrast CT images, respectively; L-S_pre and L-S_post refer to the difference in mean HU between the liver and spleen on pre- and post-contrast CT images, respectively. *Calculated using z-statistics.
