This AI tool can detect strokes in minutes instead of hours
It’s trained to read brain scans automatically, from identifying debilitating and potentially fatal strokes or aneurysms to alerting a specialist to take a closer look so that the patient can begin treatment sooner.
Every minute lost in stroke diagnosis can mean millions of dead brain cells and long-term disability. The AI tool, Viz.ai, is trained on thousands of brain scans and can detect strokes and aneurysms in just 3-5 minutes, significantly reducing diagnosis times and improving patient outcomes.
Viz.ai reduces stroke diagnosis time from hours to minutes
Dr. Chris Mansi, co-founder of Viz.ai, emphasizes the urgency of stroke diagnosis. Every minute, millions of brain cells die, leading to devastating consequences. Early treatment, often involving clot removal, can make the difference between full recovery and long-term disability.
Faster diagnoses benefit not just patients but also healthcare systems and insurers. Early stroke intervention reduces disability, shortens hospital stays, and allows patients to return to work, leading to cost savings for everyone involved.
