Summary
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 prostate cancer that may have returned after a period of improvement (biochemical recurrence). 68Ga-PSMA is a radiopharmaceutical that localizes to a specific prostate cancer receptor, which can then be imaged by the PET/CT or PET/MRI scanner.
Eligibility Criteria
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
