Imaging With a PET Agent for Detection of Cancers of the Head and Neck

injection of a microdose (\< 100 ug) of \[18F\]- PARPi

"Patients will be injected with approximately 10 mCi of \[18F\]PARPi and a dynamic PET scan of will be acquired for approximately 30 minutes. A second body PET/CT scan will be started approximately 60 min post injection, and a third PET/CT scan will be started at approximately 120 min post injection. The first (dynamic) and the second (body) PET/CT scan will use ultra -low dose CT scan for attenuation correction. The last PET/CT scan will be performed with the investigator's regular clinical low-dose CT settings."
