Table 3.
Patient-based analysis on the diagnostic accuracy of PET/MRI and MRI in determining TNM stage. Positive T stage was regarded as ≥T2b
| Stage | PET/MRI | MRI | ||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Sens | Spec | Acc | PPV | NPV | AUC (95% CI) | Sens | Spec | Acc | PPV | NPV | AUC (95% CI) | |
| T stage (≥T2b 11/33) | 91% | 86% | 88% | 77% | 95% | 0.89 (0.76–1.00) | 100% | 50% | 67% | 50% | 100% | 0.75 (0.59–0.91) |
| N stage (N1 17/33) | 59% | 88% | 73% | 83% | 67% | 0.73 (0.56–0.91) | 71% | 75% | 73% | 75% | 71% | 0.73 (0.55–0.91) |
| M stage (M1 5/33) | 60% | 100% | 94% | 100% | 93% | 0.80 (0.53–1.00) | 60% | 74% | 72% | 30% | 91% | 0.67 (0.40–0.94) |
