Arterial spin labeling (ASL) is a magnetic resonance (MR) imaging technique used to assess
cerebral blood flow noninvasively by magnetically labeling inflowing blood. In this article, the …

Arterial spin labeling (ASL) is a non-invasive MRI technique to measure cerebral blood flow
(CBF). This review provides a practical guide and overview of the clinical applications of …

High-resolution phase—contrast magnetic resonance imaging can now assess flow in
proximal and distal cerebral arteries. The aim of this study was to describe how total cerebral …

Perivascular spaces (PVS) of the brain, often called Virchow-Robin spaces, comprise fluid,
cells and connective tissue, and are externally limited by astrocytic endfeet. PVS are …

White matter hyperintensities are frequent on neuroimaging of older people and are a key
feature of cerebral small vessel disease. They are commonly attributed to chronic …

Pure vascular parkinsonism without evidence of nigral Lewy body pathology may occur as a
distinct clinicopathological entity, but a much more frequent occurrence is the comorbid …

Postoperative cognitive dysfunction (POCD) has been reported with widely varying
frequency but appears to be strongly associated with aging. Outside of the surgical arena …

Arterial spin labeling (ASL) magnetic resonance imaging (MRI) has become a popular
approach for studying cerebral hemodynamics in a range of disorders and has recently …

Cerebral small vessel disease is an important cause of vascular cognitive impairment and
dementia. On brain imaging, discrete lacunar infarcts and/or more diffuse regions of white …

Background It is well established that aging and vascular processes interact to disrupt
cerebral hemodynamics in older adults. However, the independent effects of cerebral …
