Fig 4. Receiver operating characteristic (ROC) curves of ADC values for differentiation between GBM and PCL.

Fig 4

(A) The left diagram represents the ROC curves of ADC values (x10-3 mm2/s, b = 1000 sec/mm2) in the tumor necrosis (ADCn) (full line), the most strongly-enhanced tumor area (ADCt) (dash—dot line), and the peritumoral edema (ADCe) (dot line). The optimal cutoff values of ADCn, ADCt, and ADCe are 1.85, 0.77, and 1.81 respectively. Area under ROC curve (AUC) in the ADCn, ADCt, and the ADCe are 0.63, 0.78, and 0.71 respectively. (B) The middle diagram represents the ROC curve of combined ADCt and ADCe, with AUC value of 0.83. (C) The right diagram represents the ROC curve of combined ADCn, ADCt, and ADCe, with AUC value of 0.94.
