Summary
This phase II trial studies how well a positron emission tomography (PET)/computed tomography (CT) scan using fluciclovine F18 compared with a PET/CT scan with gallium Ga 68-labeled PSMA-11 works in planning radiation treatments and enhancing outcomes in patients with prostate adenocarcinoma. Fluciclovine F18 and gallium Ga 68-labeled PSMA-11 are types of tracers, called radiotracers, that are injected and can accumulate in tumor cells to develop images of them during a PET/CT scan. It is not yet known whether giving fluciclovine F18 or gallium Ga 68-labeled PSMA-11 may work better in planning radiation treatments and enhancing outcomes in patients with prostate adenocarcinoma.
