Discrepancy between mpMRI and combined PET/MRI score.
| Primary treatment | mpMRI score | PET score | PET/MRI score | Site of lesion | Consequences for choice of treatment |
|---|---|---|---|---|---|
| RP | 2 | 1 | 1 | Seminal vesicle | No |
| RP | 2 | 3 | 3 | Seminal vesicle | No |
| EBRT | 2 | 1 | 1 | Seminal vesicle | No |
| RP+ePLND | 2 | 3 | 3 | LN, pelvic | No |
| RP | 2 | 1 | 1 | LN - pelvic | Yes, EBRT field reduced |
| RP+ePLND | 2 2 |

LN, pelvic LN, pelvic LN, paraaortic |
Yes, systemic treatment due to paraaortic LN |
| EBRT+ePLND | 2 | 3 | 3 | LN – paraaortic | No* |
| RP+ePLND | 1 | 3 | 3 | Bone - pelvic | Yes, extended EBRT field |
| RP+ePLND | 2 | 1 | 1 | Bone - pelvic | No |
Patients in bold were up-staged based on PET. *patient had multiple other lymph nodes with score 3 on both mpMRI and PET/MRI and overall score for the patient was not changed. RP, radical prostatectomy; EBRT, external beam radiation therapy; ePLND, extended pelvic lymph node dissection; sEBRT, salvage EBRT; LN, lymph node.
