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

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 …

Background Impaired autoregulation may contribute to the pathogenesis of cerebral small
vessel disease. Reliable protocols for measuring microvascular reactivity are required to test …

Purpose To demonstrate the feasibility of mapping cerebrovascular reactivity (CVR) using
resting-state functional MRI (fMRI) data without gas or other challenges in patients with …

Breath holding (BH) is a viable vasodilatory stimulus for calculating functional MRI-derived
cerebral vascular reactivity (CVR). The BH technique suffers from reduced repeatability …

Blood oxygen level-dependent (BOLD) functional MRI (fMRI) is commonly used to measure
cerebrovascular reactivity (CVR), which can convey insightful information about …

Small vessel disease (SVD) is a common cause of strokes and dementia. Currently, there
are no treatments; therefore, developing and validating early biomarkers of disease …

Cerebrovascular reactivity (CVR) is typically assessed with a carbon dioxide (CO2) stimulus
combined with BOLD fMRI. Recently, resting-state (RS) BOLD fMRI has been shown …

Inducible hypercapnia is an alternative for increasing the coronary blood flow necessary to
facilitate the quantification of myocardial blood flow during hyperemia. The current study …
