NCT ID NCT06314178
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compared two artificial intelligence (AI) models to the standard Hadlock formula for estimating fetal weight from ultrasound scans. Researchers analyzed scans from 283 pregnant women between 24 and 42 weeks of pregnancy. The goal was to see if AI could be more accurate and to check for any bias based on factors like mother's weight or age.
