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.
24 wrz 2009 · MR diffusion-weighted imaging (DWI) is the most sensitive and specific technique available for demonstrating acute infarction within minutes after its occurrence, 14 and this can be combined with MR perfusion (MRP) to differentiate viable from probably nonviable hypoperfused tissue. 15–17 In the same examination, MR angiography (MRA) can ...
22 mar 2024 · Stroke rehabilitation total therapy time should be based on the person’s needs, with the amount increasing to at least three hours a day on at least five days a week. Fatigue is common; use a validated scale for early assessment. Offer vision and hearing assessment
30 kwi 2014 · A standard stroke MRI protocol has an acquisition time of less than 10 min [Scout 10 s/T2* 2 min/diffusion weighted MR-imaging (DWI) 30 s/FLAIR 2 min/perfusion imaging 1 min]. Starting the protocol with a T2*weighted sequence followed by DWI provides the minimal required imaging information within 3 min.
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.
The rapid delivery of intravenous thrombolytics within 4.5 h of the time of onset has been the most important treatment goal in patients with acute ischemic stroke. Parenchymal imaging using non-contrast brain computed tomography (CT) or diffusion-weighted imaging (DWI) is used to exclude intracranial hemorrhage and extensive infarction (Table.
Conclusions—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. (Stroke. 2014;45:1985-1991.)
