Using AI and 3D CT scans to predict rupture risk for thoracic aortic aneurysms
Machine learning-based biomechanical analysis for thoracic aortic aneurysm rupture risk assessment
This project uses machine learning plus 3D CT scans to help identify adults with thoracic aortic aneurysms—especially smaller ones—who may be at higher risk of rupture.

What this research studies
If you take part, your clinical CT images would be processed by AI that builds a 3D model of your thoracic aorta. Computational biomechanics methods would then estimate stresses on the aortic wall in near real time. Those measurements would be combined with other patient features into a probabilistic risk score that accounts for uncertainty. The team will train and test these tools on an existing set of 1,000 patient scans and on new longitudinal patient data to validate predictions. The goal is a faster, automated way to flag small aneurysms that might need closer monitoring or earlier treatment.
Who could benefit from this research
Good fit: Adults (21+) diagnosed with a thoracic aortic aneurysm who have recent CT imaging and are willing to share their scans and follow-up data are ideal candidates.
Not a fit: People without a thoracic aortic aneurysm, those with poor-quality CT imaging, or anyone needing immediate emergency care for a rupture would not benefit from this research approach.
Why it matters
Potential benefit: If successful, this approach could catch dangerous aneurysms that are smaller than current size-based rules would flag, potentially preventing sudden rupture.
How similar studies have performed: Related biomechanics and AI studies have shown promise in smaller cohorts, but combining automated 3D reconstruction, real-time stress analysis, and a probabilistic risk index is relatively novel and still under validation.
