Receiver operator characteristic (ROC) curves. Receiver operator characteristic (ROC) curves from all patient cases for detection of prostate cancer using CDI (blue line) and ADC map (red line). For whole prostate, the area under the ROC curve (A _z ) was higher for CDI (A _z  = 0.9789) than for ADC map (A _z  = 0.9183).
