AI ultrasound breakthrough predicts delivery timing for expecting mothers

RadAI Slice Newsletter

Weekly Updates in Radiology AI

Good morning, there. AI can now predict delivery timing using only standard ultrasound images.

Accurately estimating time to delivery supports clinical decision-making and resource allocation in obstetrics. This innovation may improve pregnancy outcomes, especially in low-resource settings, and marks a milestone for imaging AI in women's health.

Here’s what you need to know about Radiology AI last week:

• AI predicts delivery timing from routine ultrasound images

• Majority of parents trust AI over doctors in pediatric imaging

• AI predicts Alzheimer's protein markers from brain scans

• ChatGPT-4 Turbo monitors post-deployment radiology AI

• Plus: 6 FDA approved devices & 4 new papers.

🤰 AI predicts delivery timing from routine ultrasound images

RadAI Slice: New deep learning models can now forecast pregnant patients’ delivery dates using only ultrasound images.

The details:

• Trained on 2+ million images from thousands of pregnancies

• Achieved R² of 0.95 for term births and 0.92 for all births

• Works across all trimesters and diverse patient groups

• Improved preterm birth prediction with continuous retraining

• Does not require clinical history or other risk factors

Key takeaway: Estimating days until delivery with routine ultrasound empowers clinicians, sharpens risk management, and advances equitable prenatal care through scalable, noninvasive AI.

🤖 Majority of parents trust AI over doctors in pediatric imaging

RadAI Slice: A new survey shows parents increasingly trust AI to spot abnormalities in pediatric imaging—sometimes even more than physicians.

The details:

• Parents and caregivers surveyed on AI in kids’ healthcare

• Most said AI could be more accurate than doctors for imaging

• Highlights demand for trusted, transparent pediatric AI tools

• Published in the journal Insights Into Imaging

Key takeaway: Parental acceptance will be key to pediatric AI’s integration, potentially speeding adoption and reinforcing AI’s clinical value in family-centered care.

🧠 AI predicts Alzheimer's protein markers from brain scans

RadAI Slice: A Boston University AI tool predicts amyloid and tau—hallmarks of Alzheimer's—using imaging, genetics, and clinical data.

The details:

• Model integrates brain scans, cognitive tests, genetics, health history

• Tested on 12,000+ participants from international cohorts

• Performs robust location-specific protein prediction

• May enable earlier, accessible diagnosis and clinical trial enrollment

Key takeaway: AI-enabled, non-invasive Alzheimer's prediction could revolutionize screening and disease staging, accelerating research and personalized care globally.

⚡ ChatGPT-4 Turbo monitors post-deployment radiology AI

RadAI Slice: Researchers validated ChatGPT-4 as a scalable tool for monitoring AI models in real-world radiology practice.

The details:

• LLM checked 332,809 head CTs from 37 sites for aidoc ICH AI accuracy

• ChatGPT-4 reached 0.995 accuracy and high PPV/NPV vs radiologist ground truth

• Aidoc's errors more likely than LLM’s extraction issues

• LLM monitoring is cost-effective and reduces manual workload

Key takeaway: LLM-powered monitoring may become essential for ongoing AI QA and safety as radiology AI deployment scales in busy clinics.
