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

Brain aging and associated neurodegeneration constitute a major societal challenge as well
as one for the neuroimaging community. A full understanding of the physiological …

Cerebrovascular reactivity (CVR) is the change in cerebral blood flow (CBF) in response to a
change in a vasoactive stimulus. Paradoxical reductions in CBF in response to vasodilatory …

We define cerebral vascular reactivity (CVR) as the ratio of the change in blood oxygen level-
dependent (BOLD) magnetic resonance imaging (MRI) signal (S) to an increase in blood …

Cerebrovascular reactivity (CVR), defined as the cerebral blood flow response to a
vasoactive stimulus, is an imaging biomarker with demonstrated utility in a range of diseases …

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 …

Cerebrovascular reactivity (CVR) is often defined as the increase in cerebral blood flow
(CBF) produced by an increase in carbon dioxide (CO 2) and may be used clinically to …

Abstract Changes in cerebral blood flow (CBF) in response to hypercapnia induced changes
in vascular tone, known as cerebrovascular reactivity (CVR), can be measured using the …

Objective To improve quantitative cerebrovascular reactivity (CVR) measurements and CO 2
arrival times, we present an iterative analysis capable of decomposing different temporal …

Cerebrovascular reactivity (CVR), defined here as the Blood Oxygenation Level Dependent
(BOLD) response to a CO 2 pressure change, is a useful metric of cerebrovascular function …
