Empowering frontline maternal care with AI-assisted ultrasound
Google researchers evaluated an AI model that estimates gestational age from standardized "blind sweep" ultrasounds performed by novice operators, reporting a mean absolute error of 4.18 days versus 4.48 days for expert sonographers across cohorts in Chicago and Nairobi. The model, minimally tuned on 120 Chicago participants and tested with no Nairobi data, achieved MAEs of 4.10 and 4.27 days respectively, as published in JAMA Network Open.
Why it matters: It offers a concrete, peer-reviewed data point on whether AI-assisted ultrasound can generalize across hardware and clinical settings without expert sonographers.
