Receiver operating characteristic (ROC) curves generated for 
by varying probability threshold, α ∈ [0, 1], for the top-performing feature in each feature class. ROC curves for second-order textural kinetic feature, contrast inverse moment; first-order textural kinetic feature, median gray level; morphology feature, smoothness; the Gabor filter channel corresponding to 
for the precontrast image; peak postcontrast texture, intensity variance, and kinetic signal intensity are shown.
