Measures of sensitivity, specificity, PPV, NPV, accuracy, and AUC of ADCmin values, rADC ratios, and rCBVmax 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.
