Specific DWI lesion patterns predict prognosis after acute ischaemic stroke within the MCA territory.
BACKGROUND Apart from diffusion-weighted imaging (DWI) lesion volume and diffusion-perfusion mismatching, there is limited information about neuroradiological predictors of early prognosis after an ischaemic stroke. This study sought to identify specific DWI lesion patterns that would help prediction of early prognosis of three different endpoints: unstable hospital course, recurrence of stroke...
متن کاملCan DWI-ASPECTS substitute for lesion volume in acute stroke?
BACKGROUND AND PURPOSE The extent of diffusion lesion on pretreatment imaging is a risk factor for poor outcome and hemorrhagic transformation after thrombolysis, and volumes of 70 to 100 mL have been advocated as cut-offs. However, estimating diffusion-weighted imaging (DWI) lesion volume (VolDWI) in the acute setting may be cumbersome. We aimed to determine whether the DWI-Alberta Stroke Prog...
متن کاملDWI Intensity Values Predict FLAIR Lesions in Acute Ischemic Stroke
BACKGROUND AND PURPOSE In acute stroke, the DWI-FLAIR mismatch allows for the allocation of patients to the thrombolysis window (<4.5 hours). FLAIR-lesions, however, may be challenging to assess. In comparison, DWI may be a useful bio-marker owing to high lesion contrast. We investigated the performance of a relative DWI signal intensity (rSI) threshold to predict the presence of FLAIR-lesions ...
متن کاملAcute Phase Reactants as a Prognostic Factor in Acute Stroke
Introduction: Elevated levels of CRP are present among patients at risk for further first-ever myocardial infarction and stroke. It has been shown that after ischemic stroke, increased levels of CRP are associated with unfavorable outcomes. Methods: From 120 patients admitted to the emergency unit of our hospital with the diagnosis of stroke CRP, D-dimer and ferritin level was measured and the ...
متن کاملDiffusion- and perfusion-weighted MRI. The DWI/PWI mismatch region in acute stroke.
BACKGROUND AND PURPOSE Diffusion-weighted imaging (DWI) and perfusion-weighted imaging (PWI) are relatively new MR techniques increasingly used in acute stroke. During the first hours of stroke evolution, the regions with abnormal perfusion are typically larger than the DWI lesions, and this mismatch region has been suggested to be "tissue at risk." The aim of this study was to evaluate the PWI...
