ROC curves including the model cutoff values, sensitivity, specificity, and AUC for differentiating the tumor grades (I from II; and II from III). A ROC curve obtained from the model fitted to ADC histogram parameters for differentiating grade I and II meningioma tumors. B ROC curve obtained from the model fitted to post-contrast T1WI histogram parameters for differentiating grades I and II meningioma tumors. C ROC curve obtained from the model fitted to T2WI-FLAIR histogram parameters for differentiating grades I and II meningioma tumors. D ROC curve obtained from the model fitted to ADC histogram parameters for differentiating grades II and III meningioma tumors. E ROC curve obtained from the model fitted to post-contrast T1WI histogram parameters for differentiating grades II and III meningioma tumors. F ROC curve obtained from the model fitted to T2WI-FLAIR histogram parameters for differentiating grades II and III meningioma tumors
