BACKGROUND AND PURPOSE: Patients with cerebrovascular occlusive disease may
develop compensatory changes in local cerebral vasculature with a resultant loss of …

Background and Purpose—Blood oxygen level–dependent (BOLD) contrast largely
depends on changes in cerebral blood flow (CBF). Because cerebrovascular disease may …

Purpose Blood oxygen level‐dependent (BOLD) functional magnetic resonance imaging
(fMRI) is a technique used to infer neuronal activity from the observed changes in blood flow …

The study aims to investigate the effect of cerebral ischemia or hypoperfusion in the
evaluation of neural activity with blood-oxygen-level dependent (BOLD) functional magnetic …

Functional MRI is based on the vascular response due to neuronal activation. The
underlying mechanism of fMRI is the blood oxygenation level-dependent (BOLD) effect—a …

Background and Purpose—Blood oxygen level-dependent MRI (BOLD MRI) of hypercapnia-
induced changes in cerebral blood flow is an emerging technique for mapping …

Blood oxygen level-dependent (BOLD) contrast MRI is a simple non-invasive method of
estimating “perfusion,” and combined with a vasodilatory stimulus, may allow estimation of …

Abstract Blood-oxygenation-level-dependent (BOLD) MRI is widely used for inferring
neuronal activation and is becoming increasingly popular for assessing cerebrovascular …

Background and Purpose—Blood oxygenation level–dependent (BOLD) functional MRI
(fMRI) is a promising method for defining brain recovery after stroke quantitatively …

Imaging of activated brain areas based on changes of blood deoxyhemoglobin levels is now
possible with MRI. Acetazolamide (ACZ) increases cerebral blood flow (CBF) without …
