BACKGROUND AND PURPOSE: The development of thrombolytic agents for use with
compromised cerebral blood flow has made it critical to quickly identify those patients to best …

BACKGROUND AND PURPOSE: Neuroimaging techniques such as diffusion-and perfusion-
weighted MR imaging have been proposed as tools for advanced diagnosis in hyperacute …

Recent data indicate that diffusion/perfusion weighted imaging could eventually play a
significant role in acute stroke management, particularly in determining the suitability of …

PURPOSE: To test diffusion-and perfusion-weighted MR imaging techniques within the
extreme time constraints of stroke evaluation before therapy, and then, with MR imaging …

With the advances in new neuroimaging modalities, the role of imaging of acute ischemic
stroke has broadened and progressed from making diagnoses to providing valuable …

Objective: In this study, perfusion CT and diffusion-weighted magnetic resonance imaging
(DWI) were compared as means of assessing the ischemic brain in hyperacute stroke …

Purpose The purpose of this study was to compare multiphasic perfusion computed
tomography (CT) with diffusion and perfusion magnetic resonance imaging (MRI) in …

The development of new therapies for treating the acute stroke patient has produced
demands for sophisticated imaging and physiologic evaluation, as demonstrated in the …

Background: Despite some limitations, a perfusion/diffusion mismatch can provide a working
estimate of the ischemic penumbra in hyperacute stroke and has successfully been used to …

BACKGROUND AND PURPOSE: Various clinical subtypes of patients presenting with
sudden-onset ischemic stroke have been recognized, but classification of those types is not …
