OBJECTIVE. Stroke is the third leading cause of death and the leading cause of severe
disability. During the??? decade of the brain??? in the 1990s, the most promising …

Purpose To evaluate the sensitivity of the perfusion parameters derived from Intravoxel

In this study, a spin‐and gradient‐echo echo‐planar imaging (SAGE EPI) MRI pulse
sequence is presented that allows simultaneous measurements of gradient‐echo and spin …

Brown adipose tissue (BAT) is the primary tissue responsible for nonshivering
thermogenesis in mammals. The amount of BAT and its level of activation help regulate the …

Imaging is a key component in the management of brain tumours, with MRI being the
preferred modality for most clinical scenarios. However, although conventional MRI provides …

Changes in cerebral hemodynamics underlie a broad spectrum of ischemic cerebrovascular
disorders. An ability to accurately and quantitatively measure hemodynamic (cerebral blood …

Changes in cerebral blood volume (CBV) and blood magnetization each induce changes in
the transverse relaxation rate of MRI signal that are associated with changes in cerebral …

Two major avenues of work converged in the late 1980's and early 1990's to give rise to
brain perfusion MRI. The development of anatomical brain MRI quickly had as a major goal …

Arterial spin labeling (ASL) is a non-contrast method of measuring cerebral perfusion with
MRI. It has several advantages over traditional contrast-based perfusion-weighted imaging …
