Perivascular Spaces and Diffusion Tensor Imaging Analysis Along the Perivascular Space Show Distinct Associations with Aging and Alzheimer's Disease.
BACKGROUND AND PURPOSE MRI-visible perivascular spaces (PVS) are structural findings on T2-weighted MRI, whereas diffusion tensor imaging analysis along the perivascular space (DTI-ALPS) measures directional water diffusivity in deep white matter. We compared PVS burden and ALPS across young controls, elderly controls,...
