ROC analysis between patients in the PML and PCNSL groups. ROC analyses demonstrated that mean MTRasym has high discriminatory power for differentiating between patients in the PML and PCNSL groups. When an AUC value of < 0.0165 was used as the threshold for diagnosis, the sensitivity, specificity, positive predictive value, and negative predictive value were all 100%.
