Pragmatic Study on the Use of 68Ga-PSMA-617 PET/CT Imaging as a Standard of Care to Influence Clinical Management of Tumors Overexpressing PSMA.

This project aims to monitor the innocuity/safety profile of cyclotron-produced [68Ga]-PSMA-617 PET imaging in PSMA-expressing cancers.

A Phase I Study: PET Imaging of Cancer Patients Using [18F] 4-L-Fluoroglutamine (2S,4R)

This is a Phase I study. This study is the first time that a new experimental drug called 18FFluoroglutamine, or F-Glutamine, is being used in people.
