Development of a Novel 18F-DTBZ PET Imaging as a Biomarker to Monitor Neurodegeneration of PARK6 and PARK8 Parkinsonism

"Subjects will receive a single i.v. administration of approximately 10 mCi 18F-FP-(+)-DTBZ (10 nmole FP-(+)-DTBZ) immediately prior to each scan.~The proposed dose for this study is based on our phase I study. At the proposed human dose of 10 mCi, the whole body effective dose (ED) will be approximately 680 mrem. The estimated human ED is expected to be comparable to or below the range of other approved brain imaging agents, such as 18F-FDG."
