BACKGROUND AND PURPOSE: A key factor in predicting recurrent ischemic episodes in
patients with carotid artery occlusion is the presence of hemodynamic impairment. There is …

Background and Purpose—We sought to assess whether MRI, MR angiography, or 1H MR
spectroscopy can be used to identify patients with symptomatic carotid artery occlusion …

Severe carotid artery stenosis or occlusion may put patients at risk for ischaemic stroke.
Reduced cerebrovascular reserve capacity is a possible indicator of an imminent ischaemic …

Background and Purpose The importance of MR imaging in carotid artery disease is
unclear. We evaluated the sensitivity and specificity of the high signal intensity changes on …

Abstract Background and Purpose Severe intracranial atherosclerotic stenosis (SIAS)
remains at risk of recurrent ischemic events despite intensive medical management …

Quantitativeperfusion MRI is a promising new technique capable of offering information on
cerebral blood flow (CBF), cerebral blood volume (CBV), and mean transit time (MTT) …

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: Elevated OEF is a surrogate for misery perfusion. Our aim
was to detect misery perfusion in patients with unilateral steno-occlusive disease of the ICA …

Objectives: Oxygen extraction fraction (OEF) and cerebrovascular reserve (CVR) are both
proven predictors of stroke risk in symptomatic patients with carotid occlusion. Accordingly …

Background Comprehensive hemodynamic impairment mapping using blood oxygenation‐
level dependent (BOLD) cerebrovascular reactivity (CVR) can be used to identify …
