Research on the Application of 68Ga-PSMA-CYC PET Imaging in the Diagnosis, Staging, and Restaging of Prostate Cancer

This study evaluates a new type of PET imaging scan — using a tracer called 68Ga-PSMA-CYC — to detect, stage, and monitor prostate cancer. The scan targets a protein (PSMA) found abundantly on prostate cancer cells, making it highly precise at finding cancer that may be missed by conventional imaging. **You may be eligible if...** - You have confirmed prostate cancer (either newly diagnosed or previously treated) - You are referred for imaging to help with diagnosis, staging, or monitoring for recurrence - You are able to give written consent **You may NOT be eligible if...** - You have a known allergy to PSMA-based tracers - You have a medical condition that, in the doctor's opinion, would significantly affect the imaging or your safety Talk to your doctor to see if this trial is right for you.
