AZmed vs Rayscape
Two European plain radiograph companies pointed at different films. AZmed is trauma first, detecting fractures, joint effusions and dislocations, which is the highest volume plain radiograph reading in any emergency department and the one where a missed finding most reliably becomes a complaint. Rayscape is chest first, with a large findings set, longitudinal comparison across prior scans and lung nodule work on computed tomography, plus independent evaluation in a tuberculosis screening setting. They barely overlap clinically, so a department choosing between them is really choosing which reading burden to attack: the overnight trauma queue or the chest backlog. Whichever you pick, ask for performance on your own case mix rather than the aggregate figure, because prevalence changes the false positive burden more than sensitivity does.
- It is built around trauma radiography specifically, covering fractures, joint effusions and dislocations, which is the highest volume and most error prone plain film reading in any emergency department.
- Depth in one reading task is a different proposition from breadth across a findings list, and trauma is where a missed finding most often becomes a claim.
- European clearance and deployment across emergency settings mean the product has been used under time pressure rather than in a reading room.
- Breadth on chest radiography is substantial with longitudinal comparison across prior scans, plus lung nodule work on computed tomography, so it reaches beyond a single body region.
- Independent evaluation in a tuberculosis screening context is a harder test than a reader study, which is more external validation than most vendors at this size hold.
- Both on premise and cloud integration are available, which matters where images must stay inside the institution.

These read different studies for different purposes and are compared here because both are European plain radiograph vendors that a hospital might see in the same evaluation. The comparison should be run per body region and per finding rather than on aggregate claims, since a trauma product and a chest product share almost no performance surface. Neither publishes a security attestation or pricing.
For any radiograph AI, prevalence and case mix in your own population determine the false positive burden more than the published sensitivity does, and neither vendor publishes performance stratified that way.
