Multiparametric CT/MR imaging may be used to identify the extension of potential viable brain tissue (penumbra) and of irreversible brain lesion (core) using CT perfusion and/or diffusion weighed and perfusion weighted MR imaging. The status of the arterial collateral circulation and the type and ...
Imaging of brain ischemia 来自 学术范 喜欢 0 阅读量: 42 作者:Olivot,J.-M.摘要: The extent of the penumbra and the core of an acute ischemic stroke influence, at the given time, the impact of the recanalization of the occluded vessel on the outcome. Research studies have demonstrated ...
MRI and MRA of Ischemic Stroke R.G.González, inPrimer on Cerebrovascular Diseases (Second Edition), 2017 MRI of Brain Ischemia MR has greatly enhanced our understanding ofischemic stroke. It is a widely available and practical clinical tool, and is commonly employed to diagnose and guide the ...

Acute human stroke studied by whole brain echo planar diffusion-weighted magnetic resonance imaging Our purpose was to use whole brain echo planar magnetic resonance imaging (MRI) to identify and characterize diffusion abnormalities in acute cerebral isch... S Warach,J Gaa,B Siewert,... - 《...
13-17 We sought to establish the frequency of acute infarction defined by diffusion restriction detected on MRI scans among patients with mild focal neurologic, but low-risk, symptoms. We hypothesized that MRI evidence of brain ischemia confirming the diagnosis would be low and that clinical ...

I Hozumi,FC Chiu,WT Norton - 《Brain Research》 被引量: 308发表: 1990年 Serial radiography in the infant shaken impact syndrome. Certain CT and/or MRI abnormalities have been used medicolegally to time intracranial injuries from the infant shaken impact syndrome (ISIS). For example, ... MS...
To evaluate impact of glucose burden on diffusion-weighted imaging (DWI)-lesion evolution according to ischemia duration in stroke. We studied 47 patients with transcranial Doppler (TCD)-documented artery occlusion treated with intravenous tissue plasminogen activator. Hyperglycemia (HG) was defined as ...
Background and Purpose: The pathogenesis of hypoxic/ischemic brain injury is closely related to the excessive release of glutamate (Glu). The results of recent studies strongly support the hypothesis that a crucial role in Glu neurotoxic... J. Mri,D Maysinger,G Zupan,... - 《European Neuro...
