Hyperfine, Inc. highlights the results from a multi-site observational study that showed the value of using Swoop® system images to quickly assess stroke patients and help guide physicians making critical treatment decisions. This publication marks the first to include a subset of ACTION PMR study data and shows encouraging results. The study, entitled "Diffusion-Weighted Imaging and Fluid-Attenuated Inversion Recovery Mismatch on Portable, Low-Field Magnetic Resonance Imaging Among Acute Stroke Patients,?

will be published in the August 2024 issue of the Annals of Neurology. It included 71 patients and was conducted by a team from several institutions, including Massachusetts General Hospital and the University at Buffalo, two of the centers in the ACTION PMR study. The Acute Ischemic Stroke Detection with Portable MR (ACTION PMR) study is a prospective, international, multi-site observational study that aims to examine the integration of brain imaging with the portable Swoop® system into the stroke diagnosis and treatment workflow.

ACTION PMR has already enrolled over 100 patients at four institutions and is composed of a series of investigator-sponsored studies. The initial 100 patients allow for a direct comparison of stroke detection between ultra-low-field MRI, conventional high-field MRI, and CT as a means to assess the capability of stroke detection of the Swoop® system. The study will continue into a workflow phase starting later this year, evaluating the ease of access and versatility of using the Swoop® system in emergency departments and stroke centers within hospital networks.
