Two presentations at ISC build on a growing body of data demonstrating the value of AI-powered portable MR images in providing information to aid physicians in the diagnosis of acute ischemic stroke, including data from the ACTION PMR stroke study.

GUILFORD, Conn., February 06, 2025--(BUSINESS WIRE)--Hyperfine, Inc. (Nasdaq: HYPR), the groundbreaking health technology company that has redefined brain imaging with the world’s first FDA-cleared AI-powered portable magnetic resonance (MR) brain imaging system—the Swoop® system—today announced the presentation of two studies at the 2025 International Stroke Conference (ISC), which provide evidence supporting the value of AI-powered portable MRI in acute ischemic stroke triage and diagnosis. Notably, this includes patient data in the Acute Ischemic Stroke Detection with Portable MR (ACTION PMR) study.

Ohio State University, an ACTION PMR site, presented its data* from the study showing that physicians were able to use Swoop® system images to diagnose 90 percent of acute infarcts seen on conventional high-field MRI—the standard of care—and also demonstrated DWI-FLAIR mismatch, a key method of identifying acute ischemic stroke. Researchers from Massachusetts General Hospital also presented data* on stroke detection, showing that images from the Swoop® system enabled accurate differentiation of stroke versus stroke mimics with strong agreement to high-field MRI, indicating the Swoop® system’s value in evaluating patients with suspected stroke and transient ischemic attack.

The ACTION PMR study is a prospective, international, multi-site observational study that aims to examine the value and role of brain imaging with the Swoop® portable MR brain imaging system in acute ischemic stroke diagnosis and treatment. Enrollment in the study is complete with one hundred patients at four leading institutions in the US and Europe—the University at Buffalo, the University of Glasgow, Ohio State University Wexner Medical Center, and Massachusetts General Hospital. These patients enabled a direct comparison of stroke detection between portable MRI and the standard of care as a means to assess the utility of Swoop® system images in stroke detection.

ACTION PMR data has been presented at multiple leading conferences throughout the study progression, including the Radiological Society of North America (RSNA) and the European Society of Neuroradiology (ESNR). Taken together, data from patients in ACTION PMR has shown that physician diagnosis using AI-powered portable MRI images produced substantial agreement with physician diagnosis using standard-of-care imaging in detecting acute ischemic strokes. In addition, the Swoop® system showed faster time-to-scan compared to conventional MRI and good specificity in emergency stroke care.
