NC-MRI: Non-contrast MRI (readout-segmented DWI), CE-MRI: Contrast-enhanced MRI (DCE-MRI plus T2w), TP: true positives, TN: true negatives, FP: false positives, FN: false negatives, CI: confidence interval, LR+: positive likelihood ratio, LR-: negative likelihood ratio, R1: reader one, R2: reader two
