Cerebrovascular reactivity (CVR) is an indicator of cerebrovascular reserve and provides
important information about vascular health in a range of brain conditions and diseases …

The brain is a spatially heterogeneous and temporally dynamic organ, with different regions
requiring different amount of blood supply at different time. Therefore, the ability of the blood …

Cerebrovascular reactivity (CVR), the ability of cerebral vessels to dilate or constrict, has
been shown to provide valuable information in the diagnosis and treatment evaluation of …

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 …

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 …

Respiratory challenge MRI is the modification of arterial oxygen (PaO 2) and/or carbon
dioxide (PaCO 2) concentration to induce a change in cerebral function or metabolism which …

Cerebral blood flow (CBF) and oxygenation changes following both a simple breath holding
test (BHT) and a CO2 challenge can be detected with functional magnetic resonance …
