10 cze 2014 · A 6-minute multimodal MR protocol with good diagnostic quality is feasible for the evaluation of patients with acute ischemic stroke and can result in significant reduction in scan time rivaling that of the multimodal computed tomographic protocol.
Background and Purpose—If magnetic resonance imaging (MRI) is to compete with computed tomography for evaluation of patients with acute ischemic stroke, there is a need for further improvements in acquisition speed. 24 hours onset, National Institutes of Health Stroke Scale ≥3, and absence of MRI contraindications.
Low-field (LF) MRI (<0.5T) can detect several types of brain injury, including ischaemic and haemorrhagic stroke. Implementing LF-MRI in acute stroke care may offer several advantages, including extended applicability, increased safety, faster administration, reduced staffing and costs.
1 cze 2014 · Imaging plays a critical role in the evaluation and treatment of patients with acute ischemic stroke, especially those who are being considered for thrombolytic or endovascular therapy. Time from stroke-symptom onset to treatment is a strong predictor of long-term functional outcome after stroke.
30 kwi 2014 · Based on standardized stroke MRI protocols from 6 university hospitals, imaging studies from 62 ICH patients and 62 nonhemorrhagic stroke patients, all imaged within the first 6 h after symptom onset were analyzed. The experts identified ICH with 100 % sensitivity and accuracy.
In this review, we describe the use of MRI and its associated challenges to measure vascular and neuronal remodeling in response to spontaneous and therapy-induced stroke recovery. We demonstrate that MRI methodologies may be used in real-time monitoring of recovery from stroke. (Stroke. 2010;41:410-414.)
11 mar 2024 · Thus, the primary aim was to evaluate the diagnostic performance of the fast multi-contrast brain MRI sequence NeuroMix against the reference standard for detecting acute infarction on DWI in patients with suspected stroke and MRI performed early, within the first 12 h from initial CT evaluation.
