Portable MRI Shows 6.35-Hour Advantage in Emergency Brain Imaging According to PRIME Study Results
PRIME Study Finds Portable MRI Cuts Imaging Wait Time from 7.76 to 1.28 Hours
Hyperfine (NASDAQ: HYPR) today announced pivotal findings from the PRIME study, unveiled at the Society for Academic Emergency Medicine’s Annual Meeting, underscoring the impact of its FDA-cleared portable MRI system in emergency departments. The study compared traditional MRI processes to a workflow leveraging portable MRI at the patient’s bedside.
Rapid Bedside Imaging Improves Triage Decisions and Critical Diagnosis
The single-center, randomized controlled PRIME trial involved 100 participants with suspected neurological emergencies. Results show that the median time from imaging order to scan start was reduced from 7.76 hours with conventional MRI to just 1.28 hours with portable MRI—a median reduction of 6.35 hours. Importantly, 18.6% of completed scans revealed critical neurological findings such as acute ischemic stroke and mass lesions, all of which were detected reliably by the portable system.
| Workflow Type | Median Time to Scan Start (Hours) | Detected Critical Pathology % | Number of Patients |
|---|---|---|---|
| Portable MRI | 1.28 | 18.6% | 100 |
| Conventional MRI | 7.76 | 18.6% | 100 |
Potential to Reduce Emergency Department Bottlenecks and Boarding
Clinical experts from Yale University, who led the study, emphasized that integrating portable MRI into emergency workflows allows clinicians to access actionable imaging sooner. This speed benefits not only diagnosis but also helps reduce delays caused by overloaded imaging suites, potentially decreasing the time patients spend waiting for transfer or discharge.
Broader Evidence Base for AI-Enabled Bedside Imaging in Emergency Care
The PRIME study stands out for its rapid enrollment, reflecting the urgent need for advanced imaging in emergency triage. The system evaluated—the Hyperfine Model 2 Swoop®, powered by Optive AI™—offers sharper anatomical detail and is designed for flexible use across care settings. Hyperfine’s leadership suggests these results reinforce the utility and accessibility of portable MRI as a crucial adjunct to conventional hospital infrastructure.
What It Means for Hospitals and Patients
For hospitals facing MRI availability challenges, Hyperfine’s portable solution could translate into shorter diagnostic timelines and more efficient emergency care pathways. The company continues to advance the portable MRI’s clinical use, driven by evidence of time savings and diagnostic accuracy from studies like PRIME.
Key Takeaways
- The portable MRI reduced time to imaging by more than 6 hours compared to conventional MRI in emergency departments.
- Critical neurological conditions were detected at similar rates by both portable and conventional MRI.
- The technology could help emergency teams accelerate triage decisions and reduce ED boarding related to imaging delays.
