Detection of cerebral microbleeds with dual echo T2*-weighted MR imaging at 7.0 Tesla
Introduction Increasing interest in microbleeds had led to an increasing number of studies addressing its prevalence and clinical relevance. Prevalence estimates differ substantially between studies, due to differences in image protocols and field strengths. This study assessed the visualization of cerebral microbleeds with dual echo T2*-weighted imaging at 7.0 Tesla magnetic resonance imaging ...
متن کاملThe Frequency of Cerebral Microembolism in Acute Myocardial Infarction
ABSTRACT Introduction: Stroke is more common in patients with cerebral microembolisms. Frequency of cerebral microembolisms (high intensity transient signals, HITS) in acute myocardial infarction has been reported about 17%. The factors that influence on microembolism after myocardial infarction (MI) are not definitive. Type of MI, Ejection fraction, Hx of Streptokinase is the factors that were...
متن کاملFeasibility of dual-low scheme combined with iterative reconstruction technique in acute cerebral infarction volume CT whole brain perfusion imaging
The feasibility of application of low-concentration contrast agent and low tube voltage combined with iterative reconstruction in whole brain computed tomography perfusion (CTP) imaging of patients with acute cerebral infarction was investigated. Fifty-nine patients who underwent whole brain CTP examination and diagnosed with acute cerebral infarction from September 2014 to March 2016 were sele...
متن کاملMR diffusion imaging of cerebral infarction in humans.
PURPOSE MR diffusion imaging was performed to investigate changes in water diffusion in patients with cerebral infarction. METHODS Diffusion maps of the apparent diffusion coefficient (ADC) were created to show local water mobility in the brain tissue in 15 patients. These ADC maps were compared with conventional T2-weighted images. RESULTS Distinct subregions with different water diffusion...
متن کاملAcute ischemic infarction defined by a region of multiple hypointense vessels on gradient-echo T2* MR imaging at 3T.
BACKGROUND AND PURPOSE During the hyperacute phase of stroke, multiple hypointense vessels were identified specifically in the ischemic territory on gradient-echo T2*-weighted MR images (GRE-T2* WI) at 3T. The area was named a "region of multiple hypointense vessels (RMHV)." The aim of this study was to assess the usefulness of RMHV for the diagnosis of acute ischemic stroke (AIS) and to establ...
