Table 3:

Sensitivity, specificity, PPV, and NPV for rCBV, ADC, and their combination in the differentiation of high-grade from low-grade gliomas

	Sensitivity	Specificity	PPV	NPV
Max rCBV ≥ 1.74	94.4%	50.0%	88%	69.6%
Min ADC ≤ 1.185	97.6%	53.1%	89%	85%
Max rCBV ≥ 1.74 OR Min ADC ≤ 1.185	98.4%	31.3%	84.7%	83.3%
Max rCBV ≥ 1.74 AND Min ADC ≤ 1.185	93.5%	71.9%	92.8%	74.2%

Note:—PPV indicates positive predictive value; NPV, negative predictive value; Max, maximum; Min, minimum.
