PURPOSE To investigate the causal connections between ischemia and the hyperintensity
in diffusion-weighted MR images that has been associated with it. METHODS Diffusion …

The purpose of the present study was to quantify the early changes which occur on diffusion‐
weighted imaging following focal cerebral ischaemia. We have developed a method for the …

The regional evolution of brain infarction was studied in Wistar rats submitted to remotely
controlled thread occlusion of the middle cerebral artery. Occlusion was performed in the …

Background and purpose Diffusion-weighted magnetic resonance imaging (MRI) has been
shown to be effective in detailing regions of cerebral ischemia in which water proton …

High speed magnetic resonance imaging (MRI) and short diffusion times are used to
investigate the appearance of restricted diffusion in three different models of cerebral …

Diffusion-weighted magnetic resonance imaging (DWI) can quantitatively display focal brain
abnormalities within minutes after the onset of ischemia. We performed the present study to …

Diffusion magnetic resonance imaging provides an early marker of acute cerebral ischemic
injury. Thrombolytic reversal of diffusion abnormalities has not previously been …

Using a transorbital approach we induced the temporal occlusion and reperfusion model in
18 cats. A vascular clamp was placed on the main trunk of the left middle cerebral artery …

The purpose of this study was to ascertain if the signal intensity ratio and the lesion area
determined by diffusion-weighted magnetic resonance imaging during brief focal ischemia …

Over the last few years, diffusion and perfusion magnetic resonance (MR) imaging methods
have found increasing user for monitoring the effects of cerebral ischemia under clinical and …
