Beta Amyloid PET Imaging for Alzheimer Disease: [18F]-Fluselenamyl (Alternative Vehicle) Comparison With [11C]-PIB (FSA-PIB AD)
Washington University School of Medicine
Summary
The purpose of this research study is to determine the safety of a radiotracer 18F-Fluselenamyl using positron emission tomography (PET) imaging.
Description
The investigators will first complete whole-body PET dosimetry studies in healthy adult normal volunteers to calculate the actual radiation dose of each human organ and determine the allowable dose for a human subject when receiving a single dose for a PET scan. Second, imaging of the brain and neck will be completed in a wide range of ages of healthy adult normal control participants and participants with mild cognitive impairment, both male and females to characterize 18F-Fluselenamyl uptake in the brain, its binding to beta-amyloid plaques, and radiolabeled metabolite will be completed.

Interventions
- Drug18F-Fluselenamyl
Participants will receive a single intravenous bolus injection of 10 mCi ± 20% of the investigational radiotracer 18F-Fluselenamyl and will undergo an 18F-Fluselenamyl PET/CT scan of the head and neck.
