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.
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 demonst...
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.
1 lis 2013 · In acute stroke patients presenting with posterior fossa infarction, imaging recommendations are similar to hemispheric acute ischemic stroke. MR imaging with DWI is the optimal imaging technique to assess the presence and extent of ischemia in the posterior fossa.
1 kwi 1999 · Methods—We investigated 9 patients with hyperacute ICH with CT followed immediately by a standardized mMRI stroke protocol (DWI, PWI [T2*-WI], FLAIR, T2-WI, and MRA). The time interval between MRI and symptom onset ranged from 3 hours to 5 hours 45 minutes.
15 lut 2020 · In this chapter we review recent advances in stroke triage and treatment and provide recommendations to optimize stroke imaging workflow in clinical practice. Rapid yet comprehensive CT or MRI protocols are required for patients with suspected acute stroke.
13 cze 2024 · Neuroimaging in the evaluation of acute stroke is used to differentiate hemorrhage from ischemic stroke, to assess the degree of brain injury, and to identify the vascular lesion responsible for the stroke. Multimodal computed tomography (CT) and magnetic resonance imaging (MRI), including perfusion imaging, can distinguish between brain tissue ...
