      Abstract Brain iron deposits (IDs) are indicative of microvessel dysfunction which may predispose to small vessel disease (SVD) braindamage and worsen cognition later in life. Visible perivascular spaces in the centrum semiovale (CSO-PVS) are SVD featureslinked with microvessel dysfunction.

Small vessel function measures included: basal ganglia and centrum semiovale perfo-rating artery blood flow velocity and pulsatility, vascular reactivity to a visual stimulus in the occipital cortex and reactivity to hypercapnia in the cortex, subcortical gray matter, white matter, and white matter hyperintensities.

The decrease in Hct in the centrum semiovale with reduced CBF would lead to a reduction in oxygen delivery, which might be related to the high incidence of centrum semiovale infarct in ICA occlusion.

      The white matter at the centrum semiovale level was selected as the region of interest (ROI). The ROI metabolism parameters, including N-acetyl-l-aspartic acid (NAA), creatine (Cr), and choline (Cho) were measured by MRS. Microscopic parameters such as mean diffusion (MD) and fractional anisotropy (FA) in ROI were obtained by DTI.
