Summary

This study is testing a new artificial intelligence (AI) system that reads ultrasound videos to help doctors diagnose placenta accreta spectrum (PAS), a condition where the placenta grows too deeply into the womb. About 561 pregnant women aged 18-45 with certain risk factors will have a standardized ultrasound recording, and the AI's accuracy will be compared to standard diagnosis. The goal is to make prenatal screening faster and more reliable.
