Due to the increase in Alzheimer's disease (AD) and related dementia, age-related cognitive and functional declines are becoming more common
In this study, the authors used WM venous density as a semi-quantitative estimate to assess the visibility
Results of the study

When examining the association between WM venous density and cognitive assessment, WM venous density tends

In this study, the authors quantitatively assessed venous oxygen saturation-dependent visibility of the WM venous vasculature on high-resolution SWI in a group of
Previous studies have shown that decreased venous visibility and venous density on SWI images in patients with multiple sclerosis (MS) suggest that degenerative MS may lead to altered neuronal metabolism, consistent with quantitative measurements using brain oxygen metabolic rate
