Summary

This study looks at whether special imaging features from scans can help predict serious outcomes like amputation or death in people with peripheral artery disease (PAD) after they have had a procedure to open blocked leg arteries. Researchers will analyze 200 patients' scans to find patterns that could help doctors better assess risk before surgery. The goal is to improve personalized treatment decisions, not to test a new treatment.
