WorkingCompany's own claimOfficial ↗

Problem

Sonographers had to pause pregnancy scans to save images and take measurements. These interruptions consumed time that could be spent examining concerns or speaking with parents.

Approach

The trust and King's College London tested AI-assisted ultrasound with 78 pregnant participants and 58 sonographers. Each participant received an assisted scan and a standard scan. The AI automated image capture and measurements.

Results

40%shorter scans than standard scans in the trial, according to the trust's magazineCompany's own claim[1]

Takeaway

The comparison used both methods on each participant. The reported time savings were trial results rather than a measurement across routine hospital services.
