Accuracy of proton MR spectroscopy for distinction of benign and malignant PNSTs
| MR Spectroscopy Method of Analysis | Sensitivity (%) | Specificity (%) | Positive Predictive Value (%) | Negative Predictive Value (%) |
|---|---|---|---|---|
| Qualitative (presence of TMA peak) | 100.0 | 50.0 | 40.0 | 100.0 |
| Quantitative (TMA fraction > 50%) | 100.0 | 72.2 | 54.5 | 100.0 |
