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.
Schematic view of our 6-minute MRI stroke protocol. CE-MRA indicates contrast-enhanced magnetic resonance angiography; DSC, dynamic susceptibility contrast; DWI, diffusion-weighted imaging; EPI-FLAIR, echo-planar imag-ing-fluid attenuation inversion recovery imaging; EPI-GRE, EPI-gradient recalled echo; and MRI, magnetic resonance imaging. Table 1.
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 · Evidence reviews of individual rehabilitation therapies found that intensive physiotherapy of one to two hours a day resulted in improvements in activities of daily living, and people who have had a stroke reported faster recovery, especially within the first six months, compared with usual care.
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 · 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.
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.
