Sarcoidosis is a multisystem inflammatory disease of unknown origin, characterized by non-caseating granulomas that affect various organs, including the heart. Diagnosing CS presents significant challenges. While endomyocardial biopsy is considered the gold standard, it often has limited sensitivity due to the patchy distribution of the disease. Moreover, clinical presentations are nonspecific, ranging from asymptomatic to severe manifestations. As a result, the diagnostic criteria established by the Japanese Circulation Society (JCS) emphasize a multimodal diagnostic approach, highlighting the essential role of imaging in the evaluation of suspected CS cases. Recent advancements in imaging, particularly hybrid PET/MRI, have provided a more comprehensive evaluation of CS.
