Background and Purpose—Numerous imaging techniques have been developed and
applied to evaluate brain hemodynamics. Among these are positron emission tomography …

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

Viability of the cerebral parenchyma is dependent on cerebral blood flow (CBF), which is
usually kept in a very narrow range due to efficient autoregulation processes and can be …

Background: While stable xenon CT (Xe-CT) cerebral blood flow (CBF) is an accepted
standard for quantitative assessment of cerebral hemodynamics, the accuracy of magnetic …

Background and Purpose—Perfusion-weighted magnetic resonance imaging (PWI) is a
reliable and semiquantitative method for estimating cerebral hemodynamics. We sought to …

While H215O positron emission tomography (PET) is still the gold standard in the
quantitative assessment of cerebral perfusion (rCBF), its technical challenge, limited …

Numerous techniques have been proposed in the last 15 years to measure various
perfusion‐related parameters in the brain. In particular, two approaches have proven …

Dynamic susceptibility contrast (DSC)-based perfusion analysis from MR images has
become an established method for analysis of cerebral blood volume (CBV) in glioma …

Background and Purpose—Besides the delineation of hypoperfused brain tissue, the
characterization of ischemia with respect to severity is of major clinical relevance, because …

The availability of rapid imaging with multidetector CT systems and commercial analysis
software has made perfusion imaging with CT an everyday technique, not only for the brain …
