Workflow begins before imaging. Stroke patient journey often starts with the “stroke pager”.

Getting Viz earlier in the workflow:

  • Provides clinical team with early patient information and immediate ability to chat
  • Start synchronizing care before the patient enters the hospital

Viz connects neurology and cardiology to facilitate cryptogenic follow up. A consult/referral for continuous monitoring for atrial fibrillation can be made directly within the app.

The only clinically validated technology indicated to automatically detect and triage suspected LVOs using AI

Uses AI to automatically detect and triage suspected large vessel occlusions across hub and spoke networks.

  • AI Powered Suspected LVO Detection
  • Real time specialist notifications
  • Fast triage across hub and spoke or within thrombectomy capable institutions

World's Largest AI Detection Data Set

Real World LVO Performance

In CTAs from 2,544 consecutive patients across 139 US hospitals using scanners from multiple manufacturers,* Viz LVO has demonstrated 96% sensitivity and 94% specificity identifying LVOs. This is the only peer reviewed data describing the performance of AI powered stroke triage in the real world from any manufacturer.
