متن کاملDetecting Cerebral Microbleeds on Susceptibility-Weighted MR Imaging: Comparison with the Conventional MR Imaging Sequences
spontaneous, homogeneous, round foci of low signal intensity on the gradient-recalled echo (GRE) imaging sequence (1, 2). The prevalence of microbleeds in healthy adults is about 5% (2). Microbleeds may be a marker for cerebral microangiopathy and small vessel disease, and they may be a prognostic indicator for potential future bleeding, and especially for patients with ischemic or hemorrhagic ...
متن کاملDiffusion-weighted imaging hyperintensities in intracerebral hemorrhage: microinfarcts or microbleeds?
As reported in “Predictors of Highly Prevalent Brain Ischemia in Intracerebral Hemorrhage,” a high prevalence of diffusionweighted imaging hyperintense lesions (DWIHLs) in patients with spontaneous intracerebral hemorrhage is being recognized. These lesions have strong associations with subclinical markers of small vessel disease (SVD) such as cerebral microbleeds (CMBs). In view of the restric...
متن کاملMR imaging detection of cerebral microbleeds: effect of susceptibility-weighted imaging, section thickness, and field strength.
BACKGROUND AND PURPOSE The emergence of cerebral microbleeds (CMB) as common MR imaging findings raises the question of how MR imaging parameters influence CMB detection. To evaluate the effects of modified gradient recalled-echo (GRE) MR imaging methods, we performed an analysis of sequence, section thickness, and field strength on CMB imaging properties and detection in subjects with cerebral...
متن کاملDiffusion-Weighted MR Imaging of Intracerebral Hemorrhage
OBJECTIVE To document the signal characteristics of intracerebral hemorrhage (ICH) at evolving stages on diffusion-weighted images (DWI) by comparison with conventional MR images. MATERIALS AND METHODS In our retrospective study, 38 patients with ICH underwent a set of imaging sequences that included DWI, T1-and T2-weighted imaging, and fluid-attenuated inversion recovery (FLAIR). In 33 and 1...
