Artificial intelligence is showing new potential as a tool for preventive medicine. Researchers report that a deep learning model can estimate how fast the body is ageing by analysing routine chest X-rays, often more accurately than widely used DNA-based ageing measures.
In the study, researchers evaluated a deep learning algorithm known as CXR-Age, which extracts age-related signals from standard chest X-ray images. Its performance was compared with two established epigenetic “ageing clocks” based on DNA methylation: Horvath Age and DNAm PhenoAge. The analysis included data from 2,097 adults enrolled in the Project Baseline Health Study, a large, multi-centre US research programme focused on long-term health monitoring.

The AI model demonstrated strong associations with early, subclinical signs of...
