Summary

To compare the prognosis of patients with hyperacute ischemic stroke (who arrive at the emergency department within 4.5 hours of symptom onset) managed in a standard stroke unit adherent to guidelines versus managed in Emergency Stroke Unit (a new stroke unit based on low-field magnetic resonance imaging).

Detailed description

The first MRI machines in the 1970s and 1980s were low-field due to technological limitations. As technology advanced, the focus shifted to higher field strengths to achieve better image resolution and faster scan times. Recently, there has been renewed interest in low-field MRI due to advancements in hardware and software, making them more viable for specific clinical applications, including acute stroke. Prompt and accurate imaging is crucial for diagnosing ischemic stroke and determining the appropriate treatment (e.g., thrombolysis or thrombectomy). Research has demonstrated that low-field MRI can effectively detect acute ischemic changes and distinguish between ischemic and hemorrhagic stroke. By providing accessible, cost-effective, and safe imaging, it can facilitate timely and accurate treatment, particularly in settings where high-field MRI is not readily available. This prospective, multicenter, week-wise randomized controlled trial will compare the prognosis of patients with hyperacute ischemic stroke (who arrive at the emergency department within 4.5 hours of symptom onset) managed in a standard stroke unit adherent to guidelines versus managed in Emergency Stroke Unit (a new stroke unit based on low-field magnetic resonance imaging).
