Latest Data Demonstrate Potential of the Swoop® Portable MR Imaging® System in the Follow-up of Stroke Patients Who Have Received a Thrombectomy

New study utilizes Hyperfine, Inc. portable MRI system in monitoring brain injury and evaluating physiological impacts

GUILFORD, CT – February 09, 2023 — Hyperfine, Inc. (Nasdaq: HYPR), the groundbreaking medical device company that created the Swoop® system, the world's first FDA-cleared portable MRI system, today announced the presentation of new data regarding the use of the Swoop® system in stroke patient follow-up at the 2023 International Stroke Conference (ISC) in Dallas, Texas. In this study, conducted between December 2021 and August 2022 at Yale-New Haven Hospital, researchers performed bedside portable magnetic resonance imaging (pMRI) exams in a standard non-magnetically shielded interventional radiology suite following mechanical thrombectomy procedures, with clinical and research staff present. Mechanical thrombectomy is a minimally-invasive procedure in which a clot is removed from the brain when a patient has experienced an acute ischemic stroke.

In the presentation titled Low-Field Portable MRI for Routine Post-Thrombectomy Assessment of Ongoing Brain Injury, researchers found that ultra-low-field pMRI can facilitate a post-treatment baseline for post-thrombectomy stroke patients to evaluate the impact of potential changes in blood pressure and heart rate that may impact ongoing brain injury. These findings are significant as brain imaging is not routinely available, particularly with conventional magnetic resonance imaging, following mechanical thrombectomy. The lack of post-mechanical thrombectomy imaging can preclude accurate infarction assessment¹.

“We believe these observations set the stage for using portable MRI in the dynamic environment of acute stroke intervention, where patients are at high risk for ongoing injury,” said Kevin Sheth, M.D., Professor of Neurology and Neurosurgery at Yale School of Medicine, one of the leading investigators.

“The data presented at ISC by the Yale team demonstrate that the Swoop® system delivers diagnostic images and fills a critical gap where traditional imaging methods are unavailable,” said Hyperfine, Inc. President and CEO Maria Sainz, who was also at the ISC meeting. “We are excited about the work we are doing to capture the stroke opportunity with the Swoop® system and even more encouraged given the progress we have made on image quality since the Yale data was collected.”

About Hyperfine, Inc. and the Swoop® Portable MR Imaging® System

Hyperfine, Inc. (NASDAQ: HYPR) is the groundbreaking medical technology company that created the Swoop® system, the world’s first FDA-cleared portable magnetic resonance imaging (MRI) system capable of providing neuroimaging at the point of care. The Swoop® system received initial U.S. Food and Drug Administration (FDA) clearance in 2020 as a bedside magnetic resonance imaging device for producing images that display the internal structure of the head where full diagnostic examination is not clinically practical. When interpreted by a trained physician, these images provide information that can be useful in determining a diagnosis. The Swoop® system has been approved for brain imaging in several countries, including Canada and Australia, has UKCA certification in the United Kingdom, and is also available in New Zealand and Pakistan. The mission of Hyperfine, Inc. is to revolutionize patient care globally through transformational, accessible, clinically relevant diagnostic imaging, and data solutions. Founded by Dr. Jonathan Rothberg in a technology-based incubator called 4Catalyzer, Hyperfine, Inc. scientists, engineers, and physicists developed the Swoop® system out of a passion for redefining brain imaging methodology and how clinicians can apply accessible diagnostic imaging to patient care. Traditionally, access to costly, stationary, conventional MRI technology can be inconvenient or not available when needed most. With the portable, ultra-low-field Swoop® system, Hyperfine, Inc. is redefining the neuroimaging workflow by bringing brain imaging to the patient’s bedside.
