A prospective longitudinal diffusion‐weighted and perfusion‐weighted magnetic resonance
imaging (DWI/PWI) study of stroke patients (n= 21) at five distinct time points was performed …

Diffusion‐weighted magnetic resonance imaging detects ischemic injury within minutes after
onset, and has been used to demonstrate drug efficacy in animal models of stroke. In 50 …

Diffusion‐and perfusion‐weighted magnetic resonance imaging provides important
pathophysiological information in acute brain ischemia. We performed a prospective study in …

Background and Purpose—We sought to characterize the evolution of acute ischemic stroke
by MRI and its relationship to patients' neurological outcome. Methods—Fourteen patients …

We aimed to determine the frequency and time course of the enlargement of ischemic
cerebral lesions following human stroke and to study the effect of the state of perfusion on …

Background: Diffusion-weighted (DWI) and perfusion-weighted (PWI) MRI are powerful new
techniques for the assessment of acute cerebral ischemia. However, quantitative data …

The aim of this study was to describe the clinico-radiological correlations of magnetic
resonance (MR) perfusion and diffusion-weighted imaging (DWI) abnormalities in ischemic …

Diffusion‐weighted imaging (DWI) detects small changes in water diffusion that occur in
ischemic brain. This study evaluated the clinical usefulness of a phase‐navigated spin‐echo …

Diffusion‐weighted imaging (DWI) and perfusion‐weighted imaging (PWI) can rapidly detect
lesions in acute ischemic stroke patients. The PWI volume is typically substantially larger …

Background and Purpose—An acute mismatch on diffusion-weighted MRI (DWI) and
perfusion-weighted MRI (PWI) may represent the “tissue-at-risk.” It is unclear which …
