The performance of DCE-MRI parameters in differentiation between benign and malignant sinonasal tumors
| ROIs | Threshold of time (seconds) | Sensitivity (%) | Specificity (%) | PPV (%) | NPV (%) | Accuracy (%) |
|---|---|---|---|---|---|---|
| Tpeak | 76.5 | 74.1 | 66.7 | 76.1 | 64.3 | 71.0 |
| Tmax | 143.5 | 76.7 | 61.7 | 74.2 | 64.9 | 70.6 |
| Wash out TIC | – | 69.0 | 74.1 | 79.2 | 62.5 | 71.1 |
Tpeak: Time to peak enhancement; Tmax: Time to maximum enhancement; TIC: Time-intensity curve; PPV: Positive predictive value; NPV: Negative predictive value; ROI: Region of interest; DCE-MRI: Dynamic contrast-enhanced magnetic resonance imaging.
