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

Intact, coordinated, and precisely regulated cerebrovascular responses are required for the
maintenance of cerebral metabolic homeostasis, adequate perfusion, oxygen delivery, and …

Accurate identification of brain function is necessary to understand the neurobiology of
cognitive ageing, and thereby promote well-being across the lifespan. A common tool used …

Quantitative measurements of brain perfusion are influenced by perfusion-modifiers.
Standardization of measurement conditions and correction for important modifiers is …

Transcranial Doppler (TCD) sonography is a frequently employed technique for quantifying
cerebral blood flow by assuming a constant arterial diameter. Given that exercise increases …

Arterial spin labelling (ASL) is a non-invasive magnetic resonance imaging (MRI) technique
that may provide fully quantitative regional cerebral blood flow (rCBF) images. However …

Arterial spin labeling (ASL) is a powerful noncontrast magnetic resonance imaging (MRI)
technique that enables quantitative evaluation of brain perfusion. To optimize the clinical …

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

Regional cerebral blood flow (CBF) and cerebrovascular reactivity (CVR) in young and
elderly participants were assessed using pulsed arterial spin labeling (ASL) and blood …

New Findings What is the central question of this study? Cerebrovascular reactivity (CVR) is
a common functional test to assess brain health, and impaired CVR has been associated …
