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

The regulation of cerebral blood flow (CBF) is a complex and tightly controlled function
ensuring delivery of oxygen and nutrients and removal of metabolic wastes from brain …

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

Cerebrovascular reactivity (CVR), the capacity of the brain to increase cerebral blood flow
(CBF) to meet changes in physiological demand, is an important biomarker to evaluate brain …

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) primarily affects the
respiratory system but can also lead to neurological complications. Among COVID-19 …

Introduction In the catastrophic neurologic emergency, a complete neurological exam is not
always possible or feasible given the time-sensitive nature of the underlying disease …

For the prognosis of stroke, patients with moyamoya disease (MMD) require the estimation
of remaining cerebrovascular reactivity. For this purpose, CO 2-triggered BOLD fMRI by use …

Background. In multiple sclerosis (MS), insufficient blood supply might worsen energy
deficiency of the brain tissue. Thus, cerebrovascular reactivity (CVR), which is the capacity of …

Abstract Background and Purpose Thresholds for abnormal transcranial Doppler
cerebrovascular reactivity (CVR) studies are poorly understood, especially for patients with …

The association between cerebral hemodynamics and cognitive impairment has been
reported in neurodegenerative and cerebrovascular disorders (CVD). However, it is still …
