Alterations in cerebral blood flow are common in several neurological diseases among the
elderly including stroke, cerebral small vessel disease, vascular dementia, and Alzheimer's …

Unhealthy vascular aging promotes atherogenesis, which may lead to significant internal
carotid artery stenosis (CAS) in 5 to 7.5% of older adults. The pathogenic factors that …

Background To determine the predictive value of carotid plaque characteristics for the
improvement of cognition in patients with moderate-to-severe carotid stenosis after carotid …

Extracranial carotid artery stenosis (ECAS) due to the presence of atherosclerotic plaque is
a well‐known risk factor for stroke. Several structural imaging studies have investigated the …

Improved understanding of complex hemodynamic impairments in asymptomatic internal
carotid artery stenosis (ICAS) is crucial to better assess stroke risks. Multimodal MRI is ideal …

The Circle of Willis (CoW) is the main collateral system, and its morphological variants are
more common in patients who have severe carotid artery stenosis. Earlier data suggest that …

Carotid near-occlusion is a frequently overlooked diagnosis when CTA examinations are
assessed in routine practice. To evaluate the potential value of phase-contrast MR imaging …

Background Compromised cerebral blood flow can contribute to future ischemic events in
patients with symptomatic carotid artery disease. However, there is limited knowledge of the …

An internal carotid artery (ICA) stenosis can potentially decrease the perfusion pressure to
the brain. In this study, computational fluid dynamics (CFD) was used to study if there was a …

Abstract Purpose Arterial Spin Labeling (ASL) allows for the non-invasive visualization of
brain perfusion to detect abnormalities. In unilateral carotid artery stenosis, one hemisphere …
