Sensitivity and specificity of ADC variables for differentiating lymphoma from GBM using ROC.

ROI, region of interest; ADC, apparent diffusion coefficients; min, minimum; max, maximum; SD, standard deviation; GBM, glioblastoma; AUC, area-under-the-ROC curve. ROI1 indicates whole tumor volume; ROI2, most enhancing portion; ROI3, conventional ROI method(any enhancing portion avoiding cyst). *indicates statistical significance (p<0.05).
