What is Viz.ai?
Viz.ai is an AI platform designed to improve stroke diagnosis and patient care coordination in hospital settings. The tool uses computer vision to analyse medical imaging, particularly CT scans, to help identify signs of stroke quickly. By flagging potential stroke cases automatically, it aims to reduce time to diagnosis and treatment, which is critical since stroke outcomes depend heavily on rapid intervention. The platform focuses on care coordination alongside detection, helping hospitals simplify communication between emergency departments, radiology teams, and stroke specialists. This is intended to reduce delays in the care pathway. Viz.ai is available free to healthcare institutions, making it accessible to hospitals regardless of budget constraints. The tool integrates with existing hospital systems rather than requiring separate workflows.

Pros & Cons
Advantages
- Free to use, removing financial barriers for hospitals to adopt stroke detection tools
- Addresses a genuine clinical need; faster stroke detection directly improves patient outcomes
- Integrates with existing hospital infrastructure rather than requiring separate systems
- Supports the entire care pathway, not just detection
Limitations
- Effectiveness depends on image quality and hospital integration; results may vary across different institutions
- Requires staff training and buy-in for adoption to be successful
- As an AI tool, it requires oversight; it should be used to support clinical judgement, not replace it
Use Cases
Emergency departments seeking to reduce time between patient arrival and stroke specialist assessment
Hospitals wanting to improve stroke protocol compliance and consistency
Healthcare systems aiming to identify and reduce delays in their stroke care pathway
Rural or smaller hospitals with limited immediate access to specialist radiologists
