Background and Purpose—Cerebral hemodynamic and metabolic changes can
compensate for the decrease in cerebral blood flow occurring in patients with carotid …

Background and Purpose We used near-infrared spectroscopy (NIRS) to monitor the
cerebral oxygenation changes during CO2 reactivity tests. Methods Fifty healthy volunteers …

ABSTRACT BACKGROUND AND PURPOSE Transcranial Doppler (TCD) and near‐infrared
spectroscopy (NIRS) are two noninvasive diagnostic tools that have been shown to evaluate …

BACKGROUND AND PURPOSE: Perfusion imaging with dynamic susceptibility contrast MR
imaging (DSC-MRI) has been used to evaluate hemodynamic status in patients with …

Background and Purpose Near-infrared spectroscopy (NIRS) derives information about the
concentrations of oxyhemoglobin (HbO2) and deoxyhemoglobin (Hb) from measurements of …

Large vessel occlusion (LVO) stroke might cause different degrees of hemodynamic
impairment that affects microcirculation and contributes to metabolic derangement. Time …

Background: In acute stroke patients, there is a need for noninvasive measurement to
monitor blood flow-based therapies. We investigated the utility of near-infrared spectroscopy …

Background and Purpose This study was designed to determine whether transcranial
Doppler ultrasonography (TCD) may detect reduced perfusion states of the brain in patients …

Background and Purpose—Impaired cerebrovascular reserve capacity (CVC) is a risk factor
for ischemic events in patients with high-grade carotid stenosis and occlusion. In this study …

Cerebral blood flow (CBF) and the cerebral vasoreactivity was measured in patients with
cerebrovascular disease and longstanding occlusion of the common carotid artery (CCA). In …
