New PET scan aims to see hidden heart scarring in rare disease

This study tested a special PET scan to see if it can measure scarring (fibrosis) in the hearts of people with cardiac amyloidosis, a condition where abnormal proteins build up in the heart. Researchers also scanned people who had a heart attack or have hypertrophic cardiomyopathy (both involve scarring) and healthy volunteers for comparison. The goal was to see if the scan can detect and measure fibrosis, which could help doctors better understand and monitor the disease.
