Partial-volume effect on ischemic tissue-fate delineation using quantitative perfusion and diffusion imaging on a rat stroke model.
Partial-volume effects (PVE) in stroke imaging could hinder proper delineation of normal, ischemic, and at-risk tissues. Cerebral-blood-flow (CBF) and apparent diffusion coefficient (ADC) were measured at high and low resolution (HR = 128 x 128, LR = 64 x 64) in focal ischemia in rats during the acute phase. The data were evaluated for PVE on ischemic tissue classification on a pixel-by-pixel b...
متن کاملQuantitative prediction of ischemic stroke tissue fate.
Accurate prediction of ischemic tissue fate could aid clinical decision-making in the treatment of acute stroke. We investigated predictions of tissue fate for three (30-min, 60-min and permanent) stroke models in rats. Quantitative cerebral blood flow (CBF), apparent diffusion coefficient (ADC) and spin-spin relaxation time constant (T(2)) were acquired during the acute phase and at the end po...
متن کاملCharacterizing tissue fate after transient cerebral ischemia of varying duration using quantitative diffusion and perfusion imaging.
BACKGROUND AND PURPOSE The purpose of this study was to investigate the effects of reperfusion on ischemic lesion evolution and pixel-by-pixel apparent diffusion coefficient-cerebral blood flow (ADC-CBF) dynamics of core and mismatch tissues after 35, 60, and 95 minutes of transient focal ischemia in rats (n=28). METHODS Serial diffusion-, perfusion-, and T2-weighted imaging were performed up...
متن کاملTranslational perspectives on perfusion-diffusion mismatch in ischemic stroke.
Magnetic resonance imaging has tremendous potential to illuminate ischemic stroke pathophysiology and guide rational treatment decisions. Clinical applications to date have been largely limited to trials. However, recent analyses of the major clinical studies have led to refinements in selection criteria and improved understanding of the potential implications for the risk vs. benefit of thromb...
متن کاملInvestigation of Tissue Plasticity following Low-Dose Amphetamine Treatment in Transient Ischemic Rat Stroke Model Using Diffusion Tensor Imaging
Introduction: Amphetamine is a potent psychomotor stimulant that induces neuronal release of norepinephrine, dopamine and serotonin [1]. Considerable evidences have suggested that amphetamine can improve functional outcome in animal models of stroke, which is involved in the mechanisms of induced axonal growth and reinnervation of brain tissues [2]. Although enhanced neural sprouting, synaptoge...
