Conditions

Interventions

DRUG

[18F] FZTA

Participants will receive a single intravenous bolus injection of 7 ± 20% milliCurie (mCi) of the investigational radiotracer \[18F\]-FZTA. A PET-certified medical professional will prepare and administer the \[18F\]-FZTA. Prior to the administration, the dosage will be assayed in a dose calibrator and diluted with 0.9% sodium chloride (normal saline) up to a total 20 mL syringe volume. Participants will receive a maximum intravenous bolus injection of 7+20% mCi of \[18F\]-FZTA followed by a 10 mL 0.9% sodium chloride (normal saline) flush.
