One Slice, a Thousand Stories: Learning Health from CT Snapshots

Can a single CT slice hold the key to long-term health insights? In this episode of VALIANT Pulse, we spotlight the PhD work of Xin Yu at Vanderbilt, who explores how longitudinal health patterns can be revealed using just single-slice CT scans. From active learning and generative models to transformer-based segmentation, this dissertation introduces a suite of AI-powered techniques to reduce manual effort, enhance consistency, and link body composition to aging and cognitive decline. Tune in to hear how machine learning is helping reimagine what’s possible when data is limited but ambition is not.
