Developing a Novel Imaging Biomarker in the Differential Diagnosis of Parkinson's Disease and Parkinsonism

"During this study, subjects will receive a single i.v. administration of approximately 10 mCi 18F-DTBZ immediately prior to imaging.~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."
