Table 4:

Measures of sensitivity, specificity, PPV, NPV, accuracy, and AUC of ADC_min values, rADC ratios, and rCBV_max ratios for differentiation of hemangioblastomas and brain metastases

	TV	Sensitivity	Specificity	PPV	NPV	Accuracy	AUC
ADCmin	1.10	90.48%	96.67%	95.0%	93.5%	94.12%	0.968
rADC	1.54	95.24%	96.67%	95.2%	96.7%	96.08%	0.971
rCBVmax	6.59	95.24%	53.33%	58.8%	94.1%	70.59%	0.756

Note:—PPV indicates positive predictive value; NPV, negative predictive value; TV, threshold value; AUC, area under the curve.
