Cumulative evidence suggests that impaired cerebrovascular reactivity (CVR), a regulatory
response critical for maintaining neuronal health, is amongst the earliest pathological …

Arterial spin labeling (ASL) magnetic resonance imaging (MRI) has become a popular
approach for studying cerebral hemodynamics in a range of disorders and has recently …

The impact of age and biological sex on outcome in moderate/severe traumatic brain injury
(TBI) has been documented in large cohort studies, with advanced age and male sex linked …

BOLD fMRI signal has been used in conjunction with vasodilatory stimulation as a marker of
cerebrovascular reactivity (CVR): the relative change in cerebral blood flow (CBF) arising …

Background The change of microvascular function over the course of Parkinson's disease
(PD) remains unclear. Objective We aimed to ascertain regional cerebrovascular reactivity …

Velocity-selective arterial spin labelling (VSASL) MRI is insensitive to arterial transit time.
This is an advantage over other perfusion measurements, where long arterial transit times …

Neural-vascular coupling (NVC) is the process by which oxygen and nutrients are delivered
to metabolically active neurons by blood vessels. Murine models of NVC disruption have …

Cerebrovascular reactivity (CVR) is a measure of cerebral small vessels' ability to respond to
changes in metabolic demand and can be quantified using magnetic resonance imaging …

MRI offers techniques for non-invasively measuring a range of aspects of brain tissue
function. Blood oxygenation level dependent (BOLD) functional magnetic resonance …

Purpose Velocity selective arterial spin labeling (VSASL) quantification assumes that the
labeled bolus continuously moves into the imaging voxel during the post‐labeling delay …
