SECONDARY outcome

Timeframe: 6 months

Population: Data was not collected for this outcome as participants did not have conventional imaging correlates.

Number of sites with uptake on 18F-DCFPyL PET/CT and corresponding lesions identified on conventional imaging.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 6 months

Population: Data was not collected to assess this outcome measure as confirmatory biopsy was not practical to perform and histopathologic confirmation is not available.

Number of sites with 18F-DCFPyL uptake from which biopsy specimens show PSMA expression.
