A New Era in Intelligent Stroke Care

Stroke is a leading cause of permanent disability, death and healthcare costs in the U.S. and globally.¹ In the U.S., someone has a stroke every 40 seconds and someone dies from a stroke every 4 minutes.¹ Treatment with IV tPA and mechanical thrombectomy are time-dependent, making early stroke identification and notification of a specialist critical.²𝄒³

Identify LVOs Automatically

Artificial intelligence and deep learning algorithms automatically analyze CTA images to identify suspected large vessel occlusion (LVO) strokes.

Notify Specialists Directly

Notifications for suspected LVOs are sent to neurologists and interventionalists who can view the patient's CTA images on a mobile device. Median time from picture to the notification is under 6 minutes.⁴

Transfer Patients Promptly

Stroke specialists may initiate the transfer of patients to interventional centers through messaging and call capabilities connected with existing emergency and transportation services.

Treat IV tPA & Thrombectomy

Earlier involvement of stroke specialists has the potential to improve time to treatment with IV tPA and mechanical thrombectomy while ensuring only appropriate patients are transferred.


Automated LVO Identification and Triage

The Viz LVO Platform uses artificial intelligence and deep learning to analyze CTA images of the brain and notify a specialist of a suspected large vessel occlusion in parallel to the standard of care for image interpretation.
