Participants in the Community Atherosclerosis Risk-Positron Emission Tomography (ARIC-PET) study underwent brain magnetic resonance imaging and used diffusion tensor imaging to quantify the white matter hyperintensity volume and microstructure integrity
In 322 participants (43% blacks), after adjusting for demographics and cardiovascular risk, every SD increase in white matter hyperintensity volume was associated with a greater probability of increased amyloid (odds ratio [OR ] Is 1.
The results of this study show that in elderly people without dementia, there is a moderately positive correlation between high white matter signal and elevated amyloid
