| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial  | 
| Evaluate the precision of [18F]-JK-PSMA-7 PET/CT for detection of lymph node metastases during pre-therapy evaluation and to compare the precision with that of conventional imaging. | 
 
 
 | 
| E.2.2 | Secondary objectives of the trial  | 
Evaluate the precision of [18F]-JK-PSMA-7 PET/CT for intra prostatic tumour detection Evaluate impact of [18F]-JK-PSMA-7 PET/CT on the recurrence free survival.   Evaluation of the usefulness of a second [18F]-JK-PSMA-7 PET/CT performed one month after radical prostectomy and extended lymph node dissection. In case of recurrence, this second PET-CT will help in decision taking for new surgery or complementary radiotherapy.  Evaluate the potential impact of [18F]-JK-PSMA-7 PET/CT on therapeutic decisions

 | 
| E.4 | Principal exclusion criteria | 
o	Patients that already received treatment for prostate cancer. o	Patients non-eligible for surgery o	Non-compliant patients o	Subject suffers from claustrophobia or cannot tolerate confinement during PET/CT scanning procedures o	Subject does not understand the study procedure. o	Subject has recently (< 30 days) participated or is simultaneously participating in another prospective interventional clinical trial.

| E.5 End points | 
| E.5.1 | Primary end point(s) | 
| The anatomical localization of suspect lymph nodes identified by [18F]-JK-PSMA-7 pre-biopsy PET will be compared to those identified by pre-biopsy abdomino-pelvic MRI and histological examination using the extended lymph node resection template. | 
 
 
 | 
| E.5.1.1 | Timepoint(s) of evaluation of this end point | 
| after second PET/CT scan (post surgery) | 
 
 
 | 
| E.5.2 | Secondary end point(s) | 
1.[18F]-JK-PSMA-7 pre-surgical PET images of the suspected lesion will be compared to [18F]-JK-PSMA-7 post-surgical PET images. 2.In case of biochemical recurrence or persistence of elevated PSA post-surgery, a third [18F]-JK-PSMA-7 PET/CT will be acquired. In case of absence of distant recurrence detected on the PET/CT, the patient will be treated with pelvic (prostate bed and lymph node areas) radiotherapy associated with short term hormonal therapy.  In case of oligo-metastatic disease (≤3 metastatic lesions), metastases will be treated by radiotherapy or additional surgery. |
