What this research studies

From a patient's perspective, the team is developing a compact, low-field MRI that can be used at the bedside or in transport instead of moving you to a central scanner. They combine new image reconstruction and machine‑learning tools so images can be produced and interpreted quickly at the point of care. The project will deploy the device in acute stroke settings, compare its images and impact on decision-making to current imaging, and refine workflows for serial bedside scans. The goal is to make MRI more widely available during the critical early hours after a brain injury.

Who could benefit from this research

Good fit: Ideal candidates are people with suspected acute ischemic or hemorrhagic stroke who present to participating emergency departments, critical care units, or are cared for by participating EMS teams and can be scanned at the bedside or in transport.

Not a fit: Patients with MRI‑incompatible implants, severe instability preventing safe scanning, or those outside participating sites are unlikely to benefit directly from this project.

Why it matters

Potential benefit: If successful, this could speed diagnosis and treatment by providing faster, bedside brain imaging that informs urgent stroke care.

How similar studies have performed: Prior small studies, including work by this team, have shown that portable low-field MRI can produce clinically useful brain images, but large-scale evidence in acute stroke settings is still limited.
