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 …

Society of Neuroradiology, and the Foundation of the American Society of Neuroradiology
sponsored a series of working group meetings> 12 months, with the final meeting occurring …

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 …

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 …

In conventional neuroimaging, cerebrovascular reactivity (CVR) is quantified primarily using
the blood-oxygenation level-dependent (BOLD) functional MRI (fMRI) signal, specifically, as …

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

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 …

In many pathophysiologic situations, including brain neoplasms, neurodegenerative
disease, and chronic and acute ischemia, an imbalance exists between oxygen tissue …

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 …
