Clinical AI Report · October 7, 2026
Key takeaways
- Viz.ai is a hospital care coordination platform that analyzes CT scans, EKGs and echocardiograms as they are acquired and alerts care teams to time-sensitive findings.
- Viz.ai is sold on enterprise terms to hospitals and health systems, not individual physicians, and deploys as infrastructure connected to PACS and the EHR, which requires hospital IT work.
- Viz.ai has 50+ FDA-cleared algorithms covering stroke (large vessel occlusion), pulmonary embolism, aortic dissection, intracranial hemorrhage and cervical spine fractures, and says it was in nearly 2,000 hospitals at the end of 2025.
- Viz.ai is imaging triage, not general decision support: it covers only conditions with imaging-based detection algorithms and offers no drug dosing, literature search or differential diagnosis.

Who Viz.ai is for
A good fit for
- Hospitals speeding up stroke, pulmonary embolism and aortic dissection pathways
- Stroke programs that need several specialists alerted at the same time
- Health systems with IT capacity to connect imaging AI to PACS and the EHR

- Your priority condition has no imaging-based detection algorithm
What is Viz.ai?
Viz.ai is an AI care coordination platform for hospitals. It runs in the background of imaging workflows, analyzes CT scans, EKGs and echocardiograms as they are acquired, and alerts care teams when it detects time-sensitive findings such as stroke from large vessel occlusion, pulmonary embolism or aortic dissection, routing each case to the right specialist within seconds.
Viz.ai is imaging triage, not a general clinical reference. It covers only conditions that have an imaging-based detection algorithm and does not answer clinical questions. The company was founded in 2016, is based in San Francisco and says the platform processes millions of scans a year.
Is Viz.ai FDA cleared?
Viz.ai says it has 50+ FDA-cleared algorithms that analyze medical imaging data, including CT scans, EKGs and echocardiograms. That count is a vendor figure. Because it counts individual algorithms, ask which cleared algorithms cover the specific findings your hospital plans to use, such as stroke or pulmonary embolism, before signing a contract.
How much does Viz.ai cost?
Viz.ai has enterprise pricing for hospitals and health systems, and individual physicians cannot buy it directly. It is hospital infrastructure rather than a per-clinician app: it is typically deployed across radiology, neurology, cardiology and emergency departments, and connecting it to PACS and the EHR needs hospital IT work, which belongs in the budget alongside the contract.
How does Viz.ai help with stroke care?
Viz.ai’s strongest use is the stroke pathway. It flags suspected large vessel occlusion on CT and alerts the stroke team at the same time on their phones, which can shorten handoff delays. Peer-reviewed studies have reported shorter door-to-treatment times for thrombectomy in stroke workflows that use Viz.ai.
Stroke care runs on strict clocks: thrombolysis within 4.5 hours of symptom onset for eligible patients and thrombectomy up to 24 hours in selected patients. Viz.ai applies the same detection and alerting to pulmonary embolism and aortic dissection.
Does Viz.ai integrate with PACS and the EHR?
Viz.ai integrates with PACS and the EHR at the hospital infrastructure level. It is not a standalone app, so deployment requires hospital IT work. Once connected, it analyzes images as they are acquired, triages the workflow automatically and sends real-time mobile notifications to the relevant specialists instead of waiting for a manual handoff.

Viz.ai FAQ
Is Viz.ai only for stroke?
No. Besides stroke from large vessel occlusion, Viz.ai’s algorithms cover pulmonary embolism, aortic dissection, intracranial hemorrhage and cervical spine fractures, and it analyzes EKGs and echocardiograms as well as CT scans. It covers only conditions that have an imaging-based detection algorithm.
Does Viz.ai offer drug dosing or differential diagnosis?
No. Viz.ai is imaging triage, not general clinical decision support. It offers no drug dosing, literature search or differential diagnosis, so clinicians still need a clinical reference such as Vera Health or UpToDate for questions at the point of care.
How many hospitals use Viz.ai?
Viz.ai said it was deployed in nearly 2,000 hospitals at the end of 2025, when it also reported reaching profitability in its healthcare business. Both are company figures from its 2025 year-end announcement rather than independent counts.
