This Phase II study will employ Posluma PSMA PET scans both preoperatively, for evaluation of lesions prior to focal therapy, and postoperatively, for monitoring recurrence and verifying treatment success. Imaging findings from Posluma PET will be compared with standard MRI and biopsy results to validate Posluma PET as an advanced diagnostic tool for improving PCa detection in patients undergoing focal therapy as well as postoperative follow-up after the procedure.
