Diagnostic performance of parameters in differentiating high- and low-grade tumors
| Parameters | Cutoff Value | Sensitivity (%) | Specificity (%) | AUC |
|---|---|---|---|---|
| D (× 10−3 mm2/s) | ≤1.15 | 85.7 | 85.7 | 0.943 |
| D* (× 10−3 mm2/s) | >9.0 | 42.9 | 22.9 | 0.536 |
| f (%) | >14.1 | 100 | 90.0 | 0.957 |
| ADC (× 10−3 mm2/s) | ≤1.02 | 71.4 | 71.4 | 0.907 |
| D + f | ≤1.50, >16.4 | 100 | 90.0 | 0.986 |
Note:—AUC indicates area under the curve.
