Physician-reviewed
Radiology AI, explained by a radiologist.
What works in imaging AI, what doesn't, and what to ask before you buy — from a physician who has read films for fifty years.
Status: shortlist researched from each vendor’s own information, checked 17 Oct 2026. None of these vendors publishes prices. Hands-on evaluation is in progress — no tool is ranked until it has been checked by our Chief Medical Editor.

How to choose in six questions
- Is it cleared for your region and your exact use? FDA, CE/UKCA, Health Canada and TGA clear specific indications. A vendor with many clearances may not have one for the finding you need.
- Has it been tested on patients like yours? Ask for local validation or a pilot on your own studies before committing.
- How many false alerts will you handle? A tool that over-flags adds work instead of removing it. Ask for sensitivity and false-positive rates in a setting like yours.
- Does it fit your PACS and RIS? Results should appear in your normal worklist, not a separate screen.
- Where do images and reports go? Ask about hosting, de-identification and your local privacy rules (HIPAA, UK GDPR, PHIPA, the Australian Privacy Act).
- Who is responsible? The AI assists. The radiologist signs the report and stays accountable for it.
