Low-Field MRI in Stroke Code Patients

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.
