ROC curves. Receiver operating characteristic (ROC) curves derived from ADC in differencing malignant from benign lesions at three b values. The areas under the curves at b values of 600, 800, 1000 s/mm2 were 0.858, 0.870 and 0.866, respectively. There is no significant difference among three b values (P = 0.743).
