This phase II trial tests how well 18F-DCFPyL positron emission tomography (PET)/computed tomography (CT) scan works in detecting a specific molecule called prostate-specific antigen (PSMA) in patients with triple negative breast cancer (TNBC) that has spread from where it first started (primary site) to other places in the body (metastatic). PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of tracer, in the case of this research,18F-DCFPyL. Because some cancers take up 18F-DCFPyL it can be seen with PET. CT utilizes x-rays that traverse body from the outside. CT images provide an exact outline of organs and potential inflammatory tissue where it occurs in patient’s body. 18 F-DCFPyL-PET/CT may be effective in detecting PSMA expression (level) in patients with metastatic TNBC.

PRIMARY OBJECTIVE:
I. To evaluate the expression of PSMA via fluorine F 18 piflufolastat (18F-DCFPyL)-PET/CT in metastatic TNBC patients and compare it with lesion detection rate of fludeoxyglucose F18 (FDG) PET/CT.
SECONDARY OBJECTIVE:
I. Standardized uptake values (SUV) of each lesion on both FDG PET/CT and 18 F-DCFPyL-PET/CT will be compared to find a correlation between tumor aggressiveness (lesion SUV on FDG PET/CT) and tumor angiogenesis (lesion SUV on 18 F-DCFPyL-PET/CT).
OUTLINE:
Patients receive standard of care (SOC) 18F-FDG intravenously (IV) and undergo PET/CT on study. If the PET/CT is positive for metastatic disease, within 2 weeks following FDG PET/CT, patients receive 18 F-DCFPyL IV and undergo PET/CT 50 minutes post-injection.
After completion of study intervention, patients are followed up at 1 day.
