PET Scan for Sarcoidosis

A PET scan for sarcoidosis is a diagnostic imaging test that uses a small amount of radioactive sugar to detect areas of inflammation or abnormal cell activity in the body. Since sarcoidosis involves the formation of small clusters of inflammatory cells called granulomas, these areas often absorb more of the radioactive sugar and appear as bright spots on the scan. This helps doctors identify affected organs, determine the extent of the disease, and guide treatment decisions. The PET scan provides a detailed, whole-body view, aiding in accurate diagnosis and monitoring of sarcoidosis.
