This early phase I trial studies how well 18F-fluciclovine positron emission tomography (PET)/computed tomography (CT) works in staging muscle invasive bladder cancer. 18F-fluciclovine does not treat cancer; it only allows physicians to take images (pictures) of it. Staging of muscle invasive bladder cancer is currently done using CT and/or magnetic resonance imaging (MRI). Both CT and MRI are useful to determine the extent of bladder cancer, but may miss disease outside of the bladder. New techniques and imaging agents that can better identify cancer spread outside of the bladder (metastatic lesions), especially within the pelvis, are desired and would be useful.

PRIMARY OBJECTIVE:
I. To estimate the agreement rate of detecting metastatic disease between 18F-fluciclovine-PET/CT and histopathology from radical cystectomy for detecting locoregional metastatic disease in patients with cT2-T4N0M0 muscle invasive bladder cancer by conventional CT/MRI imaging.
SECONDARY OBJECTIVES:
I. To estimate the rate of detection of suspected distant metastatic disease by 18F-fluciclovine
-PET/CT in patients with cT2-T4N0M0 muscle invasive bladder cancer by conventional CT/MRI imaging.
II. To investigate the relationship between 18F-fluciclovine uptake on PET/CT and pathologic tumor stage and size of primary bladder tumor after radical cystectomy.
III. To investigate the relationship between 18F-fluciclovine uptake on PET/CT and the presence/absence of a ASCT2 and LAT1 amino acid transporters in the resected primary bladder tumors.
OUTLINE:
Patients receive 18F-fluciclovine intravenously (IV) over 10 seconds, and then undergo PET/CT for up to 60 minutes.
After completion of study, patients are followed up for 30 days.
