The 5-point of Pro-PET score based on FDG avid relative to PSMA uptake of the reference lesion.
| Pro-PET Score | |||
|---|---|---|---|
| Score | PSMA-PET | FDG-PET | Description of Reference Lesion * (n° of Lesions) |
| Pro-PET 0 | − | − | NA |
| Pro-PET 1 | + | − | NA |
| Pro-PET 2a | + | + | FDG uptake less than PSMA (≤4 lesions) |
| Pro-PET 2b | + | + | FDG uptake less than PSMA (≤5 lesions) |
| Pro-PET 3a | + | + | FDG uptake equivalent to PSMA (≤4 lesions) |
| Pro-PET 3b | + | + | FDG uptake equivalent to PSMA (≥5 lesions) |
| Pro-PET 4a | + | + | FDG uptake more than PSMA (≤4 lesions) |
| Pro-PET 4b | + | + | FDG uptake more than PSMA (≥5 lesions) |
| Pro-PET 5 | − | + | NA |
* lesion most FDG avid relative to PSMA uptake. Adapted from Adnan et al. [12] Abbreviations: FDG, fluorodeoxyglucose; NA, not available; PSMA, prostate-specific membrane antigen.
