Rate of change in AI mammogram scores may flag women needing MRI

Tracking how a woman's AI risk score increases between two screening mammograms predicts future breast cancer better than the most recent score alone. Women with the fastest score rises had a significantly higher risk. If prospective data confirm this, the velocity metric could…

• Design: Analysis of a longitudinal screening cohort; the study examined the trajectory of a commercially-available AI algorithm's risk scores across consecutive mammograms.
• Key finding: The change in score over time (velocity) improved prediction of interval and next-round cancers beyond a single-timepoint score (exact AUC/CIs not reported in source).
• Limitation: Findings are retrospective and require prospective validation before clinical implementation for MRI referral decisions.
