ROC curve for prediction of malignant lesions by ADC and TTP. At cut off ADC value of 1.3 x 10-3 mm2/sec PMA could be differentiated from MT with 88.8% sensitivity, 93.3% specificity, 88.8% PPV, 93.3% NPV, 91.6% accuracy, and 0.606 AUC. TTP of < 85 s could predict malignant parotid gland tumors with 88.9% sensitivity, 78.9% specificity, 66.7% PPV, 93.7% NPV, 82.1% accuracy, and 0.833 AUC
