AI Model Improves Detection of High-Risk Pregnancy Condition
What happened
A recent study highlights an artificial intelligence model that more accurately diagnoses placenta accreta spectrum (PAS), a life-threatening disorder. The technology analyzes patient risk factors and imaging data, reportedly outperforming current standard screening methods. This development points to the growing role of AI in perinatal risk management.
Why it matters
- The study, presented at the Society for Maternal-Fetal Medicine's 2026 meeting, was conducted by researchers at Baylor College of Medicine who retrospectively analyzed 2D ultrasound images from 113 high-risk patients at Texas Children's Hospital. - In the study, the AI model achieved 100% sensitivity, successfully identifying every confirmed case of placenta accreta spectrum (PAS); it produced two false positives but had no false negatives. - Current prenatal screening relies on ultrasound and identifying risk factors, but these methods fail to diagnose up to 50% of PAS cases before delivery. - The incidence of PAS has risen to as high as 1 in 272 pregnancies, largely attributed to increasing rates of cesarean deliveries. For women with placenta previa and two prior C-sections, the risk of developing accreta is as high as 40%. - Undiagnosed PAS is a leading cause of severe maternal morbidity and mortality, with the maternal death rate estimated to be as high as 7% in some studies. The condition can lead to massive maternal hemorrhage, organ failure, and the need for a hysterectomy. - This AI application is part of a broader trend of using machine learning in perinatal care to predict complications such as preeclampsia, gestational diabetes, and preterm labor by analyzing large datasets. - Other emerging digital technologies in high-risk pregnancy management include wearable devices for remote monitoring of biometrics like blood pressure and digital platforms designed to support patients with conditions like peripartum depression. - The full oral abstract detailing the AI model, titled "AI-based ultrasound screening for early, accurate identification of placenta accreta spectrum," is scheduled for publication in the February 2026 issue of the medical journal *PREGNANCY*.
