Table 2. Summary of the parameters in 68Ga-PSMA PET/CT and MRI groups.
| Modality | Study | Patient | Threshold effects (p-value) | Sensitivity (95% CI) | Specificity (95% CI) | LR+ (95% CI) | LR- (95% CI) | DOR (95% CI) |
|---|---|---|---|---|---|---|---|---|
| 68Ga-PSMA | 8 | 485 | 0.07 | 0.65 (0.49–0.79) | 0.94 (0.88–0.97) | 10.6 (5.1–21.9) | 0.37 (0.24–0.58) | 29 (10–80) |
| MRI | 10 | 1,487 | 0.73 | 0.41 (0.26–0.57) | 0.92 (0.86–0.95) | 4.9 (3.1–7.6) | 0.65 (0.51–0.83) | 8 (4–13) |
Values are presented as number only, median (range), or index only.
68Ga-PSMA PET/CT: 68Gallium-prostate-specific membrane antigen positron emission tomography/computed tomography, MRI: magnetic resonance imaging, CI: confidence interval, LR+: positive likelihood ratio, LR-: negative likelihood ratio, DOR: diagnostic odds ratio, AUC: area under the curve.
