Summary
Brief summary (as posted)
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.

Primary outcomes (4)
- measure
- Average SUVmax of Ga68 PSMA Uptake Outside the Expected Normal Biodistribution
- timeFrame
- an estimated average of 1 hour
- description
- The biodistribution (ie, the location(s) of physiologic radiopharmaceutical uptake within the body) of Ga68 PSMA will be evaluated using PET/CT or PET/MRI. Biodistribution will be measured by drawing regions of interest (ROI) around areas with visually appreciable increased focal uptake over background (mediastinal blood pool) and calculating a standardized uptake value maximum (SUVmax), which is a semi-quantitative measurement of the maximum value of radiopharmaceutical uptake within the ROI.

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
