Aidoc vs Viz.ai (2026)
Two triage companies answering different questions. Viz.ai's first product, ContaCT, received the 2018 De Novo authorization that created the regulation for computer aided triage and notification, and its mechanism is mobilization: Viz One alerts and connects the treating team on their phones when a finding lands. The company reports more than 50 cleared algorithms and about 2,000 hospitals and health systems. Aidoc runs aiOS, a platform that hosts its own cleared algorithms alongside partner algorithms and carries care coordination and patient management. Its January 2026 clearance (K252970) covers triage of 11 acute findings on chest, abdomen and pelvis CT, which it sells with three earlier findings as a 14 finding workflow, built on its CARE foundation model. If the minutes between detection and the team assembling are the failure, start with Viz.ai. If the problem is running many findings and models across an imaging estate from one platform, start with Aidoc.
- One platform for many models: aiOS runs Aidoc's cleared algorithms and vetted partner algorithms with continuous performance monitoring, across a reported 1,600 medical centers.
- Performance published with its denominator: in the retrospective study behind K252970, sensitivity ran from 94.0 to 99.3 percent and specificity from 95.7 to 99.3 percent across the 11 findings, on 280 cases per finding from six US sites.
- A documented data path: identifiers are stripped inside the customer's environment before upload and reattached locally when results return.
- Team mobilization is the mechanism: Viz One pairs detection with automatic alerts and team messaging on clinicians' phones, the workflow that matters in stroke, hemorrhage, pulmonary embolism and aortic disease.
- Evidence on care delivery: a post hoc analysis of a multicenter prospective randomized trial reported door to groin times 11 minutes shorter.
- Security and business associate terms published: the Trust Center names SOC 2 Type II, ISO 27001 and ISO 42001, with reports on request, and the subscription privacy policy states a BAA governs patient data.

Clinical AI for imaging triage and follow-up, delivered through aiOS, an enterprise platform that runs Aidoc's own FDA cleared algorithms alongside vetted partner algorithms and carries care coordination and patient management. Aidoc Medical was established in early 2016 in Tel Aviv and is led by co-founder and chief executive Elad Walach.

AI powered care coordination platform, Viz One, that pairs detection algorithms on imaging and ECG with automatic alerts and team messaging on clinicians' phones. It began in stroke: its large vessel occlusion product, ContaCT, received FDA's De Novo authorization in 2018 (DEN170073), which created the regulatory category for imaging triage and notification software.

Questions buyers ask
How do Aidoc and Viz.ai work with the EHR?
Aidoc ingests DICOM routed or queried from PACS and VNA or sent from modalities, plus HL7 messages, and returns results to a desktop widget, the native worklist, the reporting system, or PACS as a separate series. Authentication runs through Active Directory, a dedicated single sign on, or sign on through PACS, RIS or dictation software, a practical detail in a radiology department.
With Viz.ai, the platform receives DICOM studies from scanners and PACS, and the De Novo summary describes the notification path to the mobile app with the images attached. The app is the working surface for neurologists, interventionalists and stroke teams across hospital networks. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 27, 2026. No vendor pays for placement.
How are Aidoc and Viz.ai priced and sold?
Aidoc sells aiOS and its cleared modules to health systems under enterprise agreements through a demo, and maintains an AWS Marketplace listing, which makes the procurement channel public; the listing states that pricing depends on the duration and terms of the contract agreed with the vendor.
For Viz.ai, the website sets out how the product is sold: Viz One is an enterprise platform with therapeutic suites (neuro, vascular, cardio, pulmonary, trauma, radiology, oncology) and pilot programs, and the route in is a contact form. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 27, 2026. No vendor pays for placement.
How do Aidoc and Viz.ai handle patient data?
With Aidoc, the company's security and privacy documentation describes a new DICOM object created before upload carrying only non PHI data and a newly generated identifier; analysis runs on that object, and the identifier re-attaches PHI locally when results return.
The customer's contract sets how long Viz.ai keeps customer data. Usage data (which studies and alerts a clinician opened, response times) is de-identified to the HIPAA standard at 45 CFR 164.514 before it is used to improve services, build new products or conduct research. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 27, 2026. No vendor pays for placement.
Which settings and specialties do Aidoc and Viz.ai cover?
For Aidoc, the company reports use in more than 1,600 medical centers and names health systems including WellSpan, Mercy, Yale New Haven, St. Luke's and Renown. Validation sits at the level of each cleared indication, with its own FDA review, and the research library is organized by condition.
With Viz.ai, the oncology, respiratory, neurology and osteoporosis offers are sold as pilot programs. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 27, 2026. No vendor pays for placement.
Related comparisons
Other published head to head assessments involving these vendors or their closest peers.
Hospital counts, case volumes and Aidoc's reported tenfold reduction in false alerts are the companies' own figures, and the false alert figure has no published denominator. Viz.ai sells some modules as pilot programs, and a pilot is not a clearance.
Aidoc claims ISO 27001 certification but states no business associate status and does not say whether customer studies train its models, so ask for both. Both products triage in parallel with the standard read, and a miss in use leaves no record, so ask each what monitoring detects a missed flag. Neither publishes pricing.
