During a PET/CT scan for cardiac sarcoidosis, a special dye is injected into the body that helps to identify areas of inflammation in the heart. These areas will show up as bright spots on the scan, indicating where there may be damage or swelling in the heart tissue.
PET/CT scans can also help doctors monitor the progression of cardiac sarcoidosis over time. By comparing scans taken at different times, doctors can see how the heart is changing and whether treatment is helping to slow the progression of the disease.
