AI vs. radiologist: 400,000 women join landmark breast cancer screening trial
NCT ID NCT06934239
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This large trial compares standard mammogram reading by radiologists to reading with the help of an FDA-approved AI tool. The goal is to see if AI improves cancer detection and reduces unnecessary callbacks. About 400,000 adult women across six U.S. health systems will participate.
