RESUMO
Sarcoidosis is a systemic inflammatory disease that affects multiple organs. Various clinical signs are associated with cardiac sarcoidosis (CS), and the diagnosis process is complicated because any organ could be involved. Despite the critical clinical importance of early and precise diagnosis of CS, there is currently no gold-standard method for CS evaluation. The non-invasive imaging modalities of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) and cardiac magnetic resonance (CMR) imaging have demonstrated the potential for identifying various histological characteristics of CS. Recently, the development of hybrid FDG-PET/CMR scanners has enabled the simultaneous acquisition of these attributes. Compared to just one imaging modality, these scanners detect CS and stratify risk more accurately and with higher sensitivity. Analyzing the potential role of concurrent FDG-PET/CMR in enhancing the diagnosis of CS, the present review concentrates on the advantages of this technique in light of recent technological developments.
