This clinical trial studies gallium-68 (68Ga)-prostate specific membrane antigen (PSMA) (gallium Ga 68-labeled PSMA ligand Glu-urea-Lys[Ahx]) positron emission tomography (PET)/computed tomography (CT) or PET/magnetic resonance imaging (MRI) in identifying tumors in patients with prostate cancer that has come back after a period of improvement (recurrent). 68Ga-PSMA is a radioactive drug that may attach to specific prostate cancer cells and light up. Scanners, such as PET/CT or PET/MRI, can then be used to take pictures of the body to see where the cancer is. Using 68Ga-PSMA for PET/CT or PET/MRI may allow doctors to identify smaller tumors than standard methods.

Study summary:

PRIMARY OBJECTIVES: I. To evaluate the feasibility and biodistribution of 68Ga-PSMA. OUTLINE: Patients receive gallium Ga 68-labeled PSMA ligand Glu-urea-Lys(Ahx) intravenously (IV) and then undergo PET/CT or PET/MRI approximately 45-60 minutes later. After completion of study, patients are followed up at 24 hours and 1 week.


Inclusion Criteria: - Provides written informed consent - Known diagnosis of prostate cancer - Patient has suspected recurrence based on biochemical data (prostate specific antigen [PSA] > 2 ng/mL) - Able to remain still for duration of each imaging procedure (about one hour) Exclusion Criteria: - Unable to provide informed consent - Inability to lie still for the entire imaging time - Inability to complete the needed investigational and standard-of-care imaging examinations due to other reasons (severe claustrophobia, radiation phobia, etc.) - Any additional medical condition, serious intercurrent illness, or other extenuating circumstance that, in the opinion of the Investigator, may significantly interfere with study compliance
