Overview of the diagnostic performance of the different ultrasound methods in comparison to the current imaging standard (CT/MRI).
| Sensitivity | Specificity | PPV | NPV | Accuracy | |
|---|---|---|---|---|---|
| UGAP measurement | 70.6% | 88.9% | 92.3% | 61.5% | 76.9% |
| UGAP colour map | 100% | 77.8% | 90.0% | 100% | 92.6% |
| hyperechoic | 88.9% | 55.6% | 80.0% | 71.4% | 77.8% |
| hyperechoic + UGAP colour map | 100% | 75.0% | 94.1% | 100% | 95.0% |
