Abstract

Background: The noninvasive evaluation of nigrostriatal dopaminergic integrity by PET can provide useful information for the differential diagnosis between dementia with Lewy bodies (DLB) and Alzheimer's disease (AD). Objectives: To evaluate the diagnostic potential of imaging striatal monoaminergic terminal integrity with the novel vesicular monoamine transporter type 2 (VMAT2) radioligand [ 18F]AV-133 and PET to distinguish DLB from AD. Methods: Fifty participants [9 DLB, 11 AD, 20 Parkinson's disease (PD) and 10 healthy age-matched control subjects (HC)] underwent [ 18F]AV-133 PET studies. Additionally, 20 participants underwent amyloid imaging PET scans with either [ 11C]PiB or 18F-florb..
