ROC curves for each parameter. (A) ROC curves for the quantitative parameters K^trans, K_ep, and V_e. (B) ROC curves for the semiquantitative parameters W-in, W-out, and TTP. (C) ROC curves for ADCr and ADCe. ADCe = apparent diffusion coefficient for EPI-DWI (echo-planar imaging-diffusion-weighted magnetic resonance imaging) sequence, ADCr = apparent diffusion coefficient for RESOLVE-DWI (readout segmentation of long variable echo-trains diffusion-weighted magnetic resonance imaging) sequence, K_ep = transport rate describing the return of the contrast agent from the extravascular–extracellular space to the blood plasma, K^trans = rate of contrast agent transport from the blood plasma to the extravascular–extracellular space, ROC = receiver operating characteristic, TTP = time-to-peak enhancement after contrast agent injection, V_e =  fractional volume of the extravascular–extracellular space in the tissue, W-in = rate of contrast enhancement for contrast agent inflow, W-out = rate of contrast decay for contrast agent outflow.
