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 is the change in cerebral blood flow in response to a vasodilatory
or vasoconstrictive stimulus. Measuring variations of cerebrovascular reactivity between …

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 …

Functional magnetic resonance imaging typically measures signal increases arising from
changes in the transverse relaxation rate over small regions of the brain and associates …

Functional magnetic resonance imaging (fMRI) using the blood oxygenation level-
dependent (BOLD) contrast indirectly probes neuronal activity changes via evoked cerebral …

The dynamics of the blood oxygenation level‐dependent (BOLD) response are dependent
on changes in cerebral blood flow, cerebral blood volume and the cerebral metabolic rate of …

Purpose To evaluate the safety, tolerability, and technical feasibility of mapping
cerebrovascular reactivity (CVR) in a clinical population by using a precise prospectively …

Stimulation of cerebral vasculature using hypercapnia has been widely used to study
cerebral vascular reactivity (CVR), which can be expressed as the quantitative change in …

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 …

Background and Objectives Reduced cerebrovascular reactivity is proposed to be a feature
of cerebral amyloid angiopathy (CAA) but has not been measured directly. Employing a …
