This is a prospective trial to evaluate the effectiveness of 18F-PSMA PET-hrMRI versus standard mpMRI at identifying prostate cancer targets for HIFU therapy.
Participants with clinically localized, unilateral high grade prostate cancer (Gleason score 7-10 prostate cancer localized to one lobe on prior biopsies) OR at high risk for having unrecognized high grade prostate cancer (overall Gleason score 6 with \> half of systematic biopsy cores positive and \> 50% of core involvement in at least one core), interested in HIFU would receive both a standard mpMRI and 18F-PSMA PET-hrMRI.
Participants would then undergo a mapping biopsy using a standard sextant template plus MRI/US-fusion targeted biopsy of any lesion suspicious lesion on mpMRI or PET-hrMRI.
