OUTLINE:~Patients receive gallium Ga 68-labeled PSMA-11 intravenously (IV) then undergo PET/CT over 2-3 minutes per bed position at baseline. Patients receiving systemic therapy undergo an additional 68Ga-PSMA-11 PET/CT scan 6 weeks after initiating therapy.~After the completion of study, patients are followed for up to 5 years.
This trial studies how well 68Ga-PSMA-11 PET/CT scan works in imaging patients with prostate cancer. Diagnostic procedures, such as 68Ga-PSMA-11 PET/CT may find and diagnose prostate cancer and improve monitoring of treatment response.
