Rad AI

Generative AI for radiology reporting and follow up. Omni Impressions generates a report impression from the radiologist's dictated findings, learning each radiologist's language preferences from their historical reports. Omni Reporting auto fills structured templates from natural dictation, and Omni Unchanged pulls stable findings forward from prior reports, which the vendor reports cuts follow up dictation time by half using up to 90 percent fewer words. Continuity tracks incidental findings through to completed follow up; the vendor reports health systems using it improved follow up exam completion from roughly 30 percent to over 75 percent. Works inside existing PACS, RIS, and EHR systems. Series C reached $68 million including strategic investments from four health systems.

Capability Axes

AI Capability
AI Centrality
A
Vendor Published

Generative AI is the product. The impression, the structured report, and the carried forward prior findings are all model outputs; without the model there is no product, only dictation software.

Autonomy and Oversight Model
A
Vendor Published

Structurally the clearest oversight model in the index, because the workflow itself enforces it: the AI drafts the impression and the radiologist reviews and signs every report before it leaves. The vendor also states the tool surfaces clinically significant errors in the radiologist's own dictation in about 5 percent of reports, which positions the model as a check on the human rather than a replacement for review.

Model and Technology Transparency
Not rated
Clinical and Operational Evidence
B
Vendor Published

Specific, falsifiable operational figures with named baselines, which is better than most: follow up exam completion improved from roughly 30 percent to over 75 percent with Continuity, a reported median of one hour saved per radiologist shift, and up to 35 percent fewer dictated words. Held back from A because these are vendor and customer reported without published methodology or peer review.

Integration and Deployment
EHR and Interoperability Depth
A
Vendor Published

Operates inside the systems radiologists already use, integrating with existing microphones, PACS, RIS, and EHR rather than presenting a parallel interface, and is distributed through vendor neutral marketplaces. Workflow native by design.
