Conditions
Summary
This study evaluates the accuracy and feasibility of a portable low-field MRI (Hyperfine) device in patients presenting to the emergency department with suspected acute stroke. All enrolled patients undergo standard clinical imaging (CT, CT angiography, CT perfusion) and additionally receive a low-field MRI scan. Low-field MRI findings are compared to routine CT imaging and final clinical diagnosis. The study aims to determine whether low-field MRI can reliably detect acute ischemic stroke (including lacunar and large vessel occlusion), hemorrhagic stroke, and stroke mimics in the acute setting. Secondary outcomes include feasibility measures such as scan time, completion rate, patient satisfaction, and adverse events.

Interventions
Low-field MRI (Hyperfine Swoop, 0.064 Tesla) is performed once, in addition to routine clinical imaging (non-contrast CT, CT angiography, and CT perfusion as clinically indicated). The scan is acquired after routine imaging and after initial treatment decisions, during office hours, with the patient on their ED bed. Scan duration and any interruptions are recorded.
