Diffusion-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 Weighted MRI Patterns Caused by Acute Border Zone Infarction
nisms contributing to acute border zone infarctions. These include hemodynamic factors, embolic factors or both (1-6), and were determined by a transcranial Doppler (TCD) study and autopsies (7, 8). Before the era of magnetic resonance imaging (MRI), a computed tomography (CT) was the only method for diagnosing infarctions; however, due to limited resolution, subtle lesions caused by disseminat...
متن کاملDiffusion-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 کاملAcute small subcortical infarctions on diffusion weighted MRI: clinical presentation and aetiology.
OBJECTIVE To determine the clinical presentation and aetiology of small subcortical infarctions as found on diffusion weighted magnetic resonance imaging (DWI). DWI is both sensitive and specific in the early detection of acute ischaemic brain lesions irrespective of pre-existing vascular damage. METHODS Ninety three patients were identified showing subcortical or brainstem DWI lesions <1.5 c...
متن کاملSilent subcortical brain infarction
Introduction: The silent brain lesions detected by MRI were fairly common not only in first-ever stroke but also in normal elderly subjects. Some recent studies show the possible role of silent sub-cortical brain infarction in ischemic stroke. The aim of this study was to evaluate the frequency of silent sub-cortical brain infarction in acute first-ever ischemic stroke. Methods: In this descrip...
