68Ga-RM2 Compared to 68Ga-PSMA-617 PET/CT for Prostate Cancer Imaging According to Various Metastatic Risks

Description:

Patients with primary prostate cancer (low, intermediate or high metastatic risk) for whom radical prostatectomy is indicated, will be invited to participate to the present study. Positron Emission Tomography coupled with scanner (PET-CT) using a radiotracer : 68Ga-RM2 and Positron Emission Tomography coupled with scanner (PET-CT) using another radiotracer : 68Ga-PSMA-617, will be scheduled.
