Hyperfine’s Swoop Portable MRI System Studied in Stroke and Neurosurgical Settings

August 4, 2026—Hyperfine, Inc. announced the publication of multiple studies that provide support for the company’s Swoop imaging system across many care settings beyond its initial use in critical care.

According to the company, the Swoop portable ultra–low-field MRI systems are FDA cleared for brain imaging of patients of all ages.

The publications illustrate that the Swoop system is an emerging approach to stroke imaging, bringing value beyond the critical care environment and into the emergency department and stroke centers. They build on the evidence to support low-field portable MRI in the neurosurgical and stroke treatment sites of care, noted Hyperfine.

In the Journal of Neurosurgery, Devan Patel, MD, et al reported cases performed in an ambulatory neurosurgery center in which the Swoop system provided access to imaging immediately after endovascular neurosurgical procedures. The findings confirmed the absence of acute ischemic or intracranial hemorrhage, thus enabling same-day discharge, stated Hyperfine.

Additionally, a recently published collection of articles in Stroke demonstrated the value of low-field MRI across the stroke continuum, including prehospital stroke care, acute stroke, neurocritical care, and cerebral small vessel disease.

“These publications are important because they demonstrate the mounting clinical evidence supporting use of the Swoop system beyond the initial use in critical care, across many care settings,” commented Edmond Knopp, MD, Hyperfine Chief Medical Officer, in the company’s press release. “The cases published in the Journal of Neurosurgery provide early evidence that immediate access to on-site imaging can inform post-procedural decision-making and help avoid unnecessary delays or hospital admissions.”

Dr. Knopp continued, “In addition, the broad body of published peer-reviewed and real-world evidence in stroke care marks an important milestone in the evolution of portable, ultra-low-field MRI, strengthening clinical confidence and supporting its transition from an early-stage technology to routine clinical use. Collectively, these publications strengthen the clinical foundation of the Swoop system and highlight its potential to enable more accessible, efficient, and cost-effective neuroimaging across multiple care settings.”
