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

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

A significant component of BOLD fMRI physiological noise is caused by variations in the
depth and rate of respiration. It has previously been demonstrated that a breath-to-breath …

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 …

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 …

Cerebrovascular reactivity (CVR) reflects the capacity of blood vessels to dilate and is an
important marker for brain vascular reserve. It may provide a useful addition to the traditional …

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 …

Accurate measurements of arterial P (P) currently require blood sampling because the end‐
tidal P (P) of the expired gas often does not accurately reflect the mean alveolar P and P …

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 the cerebral hemodynamic response to a vasoactive
substance. Breath-hold (BH) induced CVR has the advantage of being non-invasive and …
