Measures of sensitivity, specificity, and accuracy in discrimination of lymphomas from GBMs with receiver operating characteristic curve analysis

Variable	CV	Sensitivity, %	Specificity, %	Accuracy, %	AUC, %	P
FA	0.192	100	80	90	0.87	.005
FA ratios	0.330	100	80	90	0.84	.010
ADC	0.818	100	90	95	0.97	<.001
ADC ratios	1.060	100	100	100	1.00	<.001

Note:—FA indicates fractional anisotropy; ADC, apparent diffusion coefficient; GBM, glioblastoma multiforme; CV, cutoff value; AUC, area under the curve.
