AI Detects Dangerous Pregnancy Condition Doctors Often Miss

Every year, thousands of pregnant women face a silent threat that doctors fail to detect until it's too late. Now, researchers have created an AI tool that spots the danger with perfect accuracy.

Scientists at Baylor College of Medicine developed an artificial intelligence program that detects placenta accreta spectrum (PAS) by analyzing ultrasound images. In a study of 113 high-risk pregnancies, the AI caught every single case of this life-threatening condition.

PAS happens when the placenta attaches too deeply to the uterine wall, usually in women who've had previous cesarean deliveries or uterine surgeries. The condition can cause massive bleeding during delivery, organ failure, and death. It's one of the leading causes of maternal mortality in the United States, and cases are rising.

The scariest part? Current screening methods only catch about half of all PAS cases before delivery. Ultrasound technicians and doctors can miss subtle warning signs, or test results come back unclear.

Dr. Alexandra Hammerquist, a maternal-fetal medicine fellow who led the research, says her team is thrilled about what this means for pregnant women. The AI reviewed 2D ultrasound images from patients who gave birth at Texas Children's Hospital between 2018 and 2025.

The results were remarkable. The AI had zero false negatives, meaning it didn't miss a single case of placenta accreta. There were only two false positives, where the AI flagged PAS that wasn't actually there. That's a trade-off most doctors would gladly accept.

The Ripple Effect

This breakthrough arrives at a critical moment for maternal health in America. As cesarean delivery rates have climbed over the past decades, so have PAS cases. Each C-section increases the risk of placenta problems in future pregnancies.

The AI tool could change everything about how doctors screen high-risk pregnancies. Instead of relying solely on human interpretation of fuzzy ultrasound images, medical teams would have a powerful second opinion that never gets tired or distracted.

Early detection means hospitals can prepare properly. When doctors know PAS is present before delivery, they can assemble specialized surgical teams, ensure blood products are ready, and plan the safest approach. These preparations dramatically reduce the risk of hemorrhage and complications.

The research team presented their findings at the Society for Maternal-Fetal Medicine's 2026 Pregnancy Meeting. Their work will be published in the journal Pregnancy this month.

Women who've had previous C-sections or uterine surgeries would benefit most from this technology. The AI screening could become a standard part of prenatal care for anyone at elevated risk.

Technology is finally catching up to one of pregnancy's most dangerous complications, giving mothers and their doctors the gift of preparation.
