New PET scan could reveal hidden heart scarring in rare disease

This study tested whether a special PET imaging probe called [68Ga]CBP8 can measure scarring (fibrosis) in the hearts of people with cardiac amyloidosis, a rare condition where abnormal proteins build up in the heart. Researchers compared 18 participants with cardiac amyloidosis to people with other heart conditions and healthy volunteers. The goal was to see if the probe binds to collagen and helps doctors better understand heart damage, not to provide a treatment.
