Diffusion-Weighted MR Imaging and Ischemic Stroke
Magnetic resonance imaging (MR) of ischemic cerebrovascular events with standard T1and T2-weighted spin-echo techniques is widely employed. Standard MR demonstrates vascular changes such as the absence of a flow void and the presence of arterial enhancement within 2-4 hours of ischemic stroke onset in some cases ( 1 ). The earliest morphologic change in the brain parenchyma, swelling, is visibl...
متن کاملTurbo spin-echo diffusion-weighted MR of ischemic stroke.
PURPOSE Our objective was to determine whether a multisection technique, diffusion-weighted half-Fourier single-shot turbo spin-echo (HASTE) imaging, can compensate for the drawbacks common to other diffusion-weighted techniques; specifically, the need for echo-planar technology and the presence of susceptibility artifacts in areas close to the skull base. METHODS Forty subjects who were refe...
متن کاملCharacterization and evolution of diffusion MR imaging abnormalities in stroke patients undergoing intra-arterial thrombolysis.
BACKGROUND AND PURPOSE Lesions revealed by pretreatment diffusion-weighted imaging (DWI) may not progress to infarction, and apparent diffusion coefficient (ADC) or DWI thresholds for tissue viability may exist. We evaluated the evolution of abnormal DWI findings in patients with acute stroke who underwent thrombolysis. METHODS Sixteen patients with acute occlusion of the anterior circulation...

15 صفحه اولRestricted diffusion on MR imaging of an acute cerebral lesion.
A 35-year-old woman with no previous medical history presented with a 3-day history of progressive left hemisensory loss, ataxia and hemiparesis. On neurological examination she had Medical Research Council (MRC) grade 4 pyramidal weakness, hyper-reflexia and mild incoordination on the left side. Sensory examination revealed decreased light touch, pain, temperature, vibration sense and proprioc...
