Detecting 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 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 کاملCerebral microbleeds on MR imaging: comparison between 1.5 and 7T.
BACKGROUND AND PURPOSE The detection of microbleeds differs strongly between studies, due to differences in scan protocol. This study aims to compare the visualization of microbleeds with 3D T2*-weighted imaging at 1.5T with 3D dual-echo T2*-weighted imaging at 7T. MATERIALS AND METHODS Thirty-four patients (29 male; mean age, 58 ± 12 years) with atherosclerotic disease from the Second Manife...

متن کاملImaging cerebral malaria with a susceptibility-weighted MR sequence.
MR Sequence Cerebral malaria is a severe complication seen in approximately 2% of patients with acute Plasmodium falciparum infection. Characteristic diffuse petechial hemorrhages that were previously only seen by gross pathologic or microscopic examination, and virtually undetectable by conventional imaging modalities, were well demonstrated in a patient with cerebral malaria, with use of susc...
