Overview
Brief Summary
Study 18F-AV-45-010 is designed to evaluate the cerebral uptake of florbetapir 18F as measured by PET imaging in frontotemporal disorder (FTD) in comparison to cognitively normal volunteers and subjects with Alzheimer's disease (AD).

Arms & Interventions
Frontotemporal Disorder
Subjects with frontotemporal disorder (FTD) received a one-time intravenous (IV) bolus injection of 300 megabecquerels (MBq) florbetapir 18F and a one-time IV bolus injection of 185 MBq of 18F-FDG.
Intervention: florbetapir 18F
Frontotemporal Disorder
Subjects with frontotemporal disorder (FTD) received a one-time intravenous (IV) bolus injection of 300 megabecquerels (MBq) florbetapir 18F and a one-time IV bolus injection of 185 MBq of 18F-FDG.
Intervention: 18F-FDG
Cognitively Normal
Cognitively normal (CN) subjects received a one-time intravenous (IV) bolus injection of 300 megabecquerels (MBq) florbetapir 18F.
Intervention: florbetapir 18F
Alzheimer's Disease
Subjects with Alzheimer's disease (AD) received a one-time intravenous (IV) bolus injection of 300 megabecquerels (MBq) florbetapir 18F.
Intervention: florbetapir 18F
Outcomes
Primary Outcomes
Qualitative Amyloid Image Assessment
Time Frame: 50-60 min after injection
Four readers blinded to all clinical information classified florbetapir Positron Emission Tomography (PET) images as either positive for amyloid or negative for amyloid. The majority read classification is presented as either positive, negative or tied.
Quantitative Amyloid Image Assessment
Time Frame: 50-60 minutes after injection
The effect of diagnostic group on mean total cortical grey matter florbetapir binding relative to cerebellar cortex is presented as standard uptake value ratios (SUVr).
