Understanding of in vivo vascular pathophysiology in white matter hyperintensities (WMHs) is still incomplete. Compared to grey matter, white matter is considerably less vascularized and tends to have lower blood flow. Therefore, sensitive detection and accurate estimation for white matter hemodynamics is crucial for early prevention and mechanistic understanding of WMHs pathogenesis and progression. In this study, we implemented advanced neurovascular MRI techniques to evaluate the white matter hemodynamics including cerebral blood flow and cerebrovascular reactivity in patients with varying degrees of WMHs.
