Cerebrovascular reactivity (CVR) magnetic resonance imaging (MRI) probes cerebral
haemodynamic changes in response to a vasodilatory stimulus. CVR closely relates to the …

Border zone or watershed infarcts are ischemic lesions that occur in characteristic locations
at the junction between two main arterial territories. These lesions constitute approximately …

Purpose Current off-label uses of acetazolamide in hospitalized patients are reviewed.
Summary Acetazolamide is a carbonic anhydrase inhibitor typically used for indications …

Arterial spin labelling (ASL) is a non-invasive magnetic resonance imaging (MRI) technique
that may provide fully quantitative regional cerebral blood flow (rCBF) images. However …

The role of cerebral pressure autoregulation (CPA) in brain injury and disorders has gained
increased interest. The CPA is often disturbed as a consequence of acute brain injury, which …

Chronic cerebral circulation insufficiency (CCCI) may not be an independent disease; rather,
it is a pervasive state of long‐term cerebral blood flow insufficiency caused by a variety of …

Respiratory challenge MRI is the modification of arterial oxygen (PaO 2) and/or carbon
dioxide (PaCO 2) concentration to induce a change in cerebral function or metabolism which …

Objective The aim of this study was to compare brain perfusion SPECT obtained from a 360°
CZT and a conventional Anger camera. Methods The 360° CZT camera utilizing a brain …

BOLD fMRI signal has been used in conjunction with vasodilatory stimulation as a marker of
cerebrovascular reactivity (CVR): the relative change in cerebral blood flow (CBF) arising …

Purpose Our objective was to demonstrate the feasibility of using hyperventilation as an
efficient vasoconstrictive challenge and prior knowledge as denoising constraints for …
