The performance of different MRI methods
| Models | Parameters | Sensitivity (%) | Specificity (%) | PPV (%) | NPV (%) | Accuracy (%) |
|---|---|---|---|---|---|---|
| DCE-MRI | Tpeak and washout TIC | 69.1 | 74.1 | 77.5 | 65.1 | 72.1 |
| DWI-MRI | WS ADCsb0,1000 | 85.3 | 81.2 | 86.4 | 79.5 | 83.7 |
| DW-MRI combined with DCE MRI | Tpeak, Washout TIC and WS ADCsb0,1000 | 90.5 | 82.7 | 88.2 | 85.9 | 87.3 |
Tpeak: Time to peak enhancement; PPV: Positive predictive value; NPV: Negative predictive value; WS: Whole slice; TIC: Time intensity curve; DCE-MRI: Dynamic contrast-enhanced magnetic resonance imaging; DWI-MRI: Diffusion-weighted imaging magnetic resonance imaging; MRI: Magnetic resonance imaging.
