Abstract


OBJECTIVE
Recently developed 18F-labelled amyloid beta (Aβ) positron emission tomography (PET) tracers have demonstrated potentials to enable more prevalent application of amyloid imaging in the clinical setting. The aim of this study is to demonstrate cerebral retention of Aβ in cognitively normal older adults, by implementing voxel-based analysis on images acquired from 18F-Florbetaben amyloid PET.
METHODS
Fifty cognitive normal elderly subjects were recruited and included in the study. Demographic data and cognitive measurements were collected. Magnetic resonance imaging (MRI) and ¹â¸F-Florbetaben PET data were obtained followed by whole brain voxel-based analysis.
RESULTS
Compared to the florbetaben (FBB) (−) counterpart, FBB (+) showed significantly higher Aβ deposition in the brain regions comprising anterior cingulate, middle cingulate, posterior cingulate and precuneus (family wise error corrected p < 0.05). There was no significant correlation between amyloid retention and cognitive functions.
CONCLUSION
Our results confirms previous results regarding Aβ deposition by using ¹â¸F-Florbetaben, demonstrating potentials in application of 18F-Florbetaben PET imaging in clinical settings.
