AI model reads cardiac MRI scans with near expert accuracy

A Penn Medicine–led team has developed a first-of-its-kind artificial intelligence system that interprets cardiac MRI scans with performance approaching expert clinicians. Trained on more than 300,000 MRI video clips from roughly 20,000 patients, the model can assess heart function and diagnose dozens of diseases using only non-contrast imaging. The work was published in Nature Biomedical Engineering.
