Cerebrovascular reactivity (CVR) is an indicator of cerebrovascular reserve and provides
important information about vascular health in a range of brain conditions and diseases …

Cerebrovascular reactivity (CVR) magnetic resonance imaging (MRI) probes cerebral
haemodynamic changes in response to a vasodilatory stimulus. CVR closely relates to the …

Cerebrovascular reactivity (CVR) is defined as the ability of vessels to alter their caliber in
response to vasoactive factors, by means of dilating or constricting, in order to increase or …

Vascular smooth muscle cells (VSMCs) are the key moderators of cerebrovascular dynamics
in response to the brain's oxygen and nutrient demands. Crucially, VSMCs may provide a …

Given adequate perfusion pressure and nonlimiting intracranial or venous pressure,
cerebral blood flow (CBF) is regulated to match cerebral metabolic rate of oxygen (CMRO2) …

Concussion is a form of traumatic brain injury (TBI) that presents with a wide spectrum of
subjective symptoms and few objective clinical findings. Emerging research suggests that …

Cerebrovascular reactivity (CVR) is an important metric of cerebrovascular health. While the
BOLD fMRI method in conjunction with carbon-dioxide (CO 2) based vascular manipulation …

Cerebral small vessel disease (SVD) pathophysiology is poorly understood.
Cerebrovascular reactivity (CVR) impairment may play a role, but evidence to date is mainly …

Objective To determine whether MRI-based cerebrovascular reactivity (CVR) can predict
cognitive performance independently of Alzheimer pathologic markers, we studied the …

Cerebrovascular reactivity, defined broadly as the ability of brain parenchyma to adjust
cerebral blood flow in response to altered metabolic demand or a vasoactive stimulus, is …
