Diffusion-Weighted MRI in Acute Lacunar Syndromes
Background and Purpose—Clinical-radiological correlation studies in lacunar syndromes have been handicapped by the low sensitivity of CT and standard MRI for acute small-vessel infarction and their difficulty in differentiating between acute and chronic lesions. Methods—We prospectively studied 43 patients presenting with a classic lacunar syndrome using diffusion-weighted MRI, a technique with...

متن کاملIdentification of embolic stroke patterns by diffusion-weighted MRI in clinically defined lacunar stroke syndromes.
BACKGROUND A number of clinical syndromes describing the presentation of deep brain infarcts are called lacunar syndromes resulting from small vessel occlusion (SVO). To verify the reliability of the clinical diagnosis "lacunar syndrome," the value was investigated with diffusion-weighted MRI (DWI). METHODS AND RESULTS A total of 73 patients (mean age 66 years; range 35 to 83 years) with sudd...
متن کاملDiffusion-weighted MRI in acute subcortical infarction.
BACKGROUND AND PURPOSE Conventional imaging lacks sensitivity and specificity for the detection of early subcortical cerebral infarction. The purposes of our study were (1) to determine the accuracy of diffusion-weighted (DW) MRI for early subcortical infarction and (2) to determine the efficacy of DW MRI for differentiating acute from nonacute subcortical infarctions when conventional MR demon...
متن کاملDiffusion- and Perfusion-Weighted Imaging in Acute Lacunar Infarction: Is There a Mismatch?
PURPOSE Characterization of lacunar infarction (LI) by use of multimodal MRI including diffusion- and perfusion-weighted imaging (DWI, PWI) is difficult because of the small lesion size. Only a few studies evaluated PWI in LI and the results are inconsistent. METHODS In 16 LI patients who underwent initial MRI within 6 hours after symptom onset and follow-up MRI within 1 week demographics, cl...
