Trial Outcomes & Findings for Imaging Characteristics of Florbetapir 18F in Patients With Frontotemporal Dementia, Alzheimer's Disease and Normal Controls. (NCT NCT01890343)

NCT ID: NCT01890343

Last Updated: 2014-09-29

Results Overview

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.
