Molecular Imaging of Cardiac Sarcoidosis

AbstractPurpose of ReviewCardiac involvement is increasingly being recognized as a cause of significant morbidity and mortality in patients with sarcoidosis. Unfortunately, imaging cardiac sarcoidosis (CS) remains a challenge and often relies on advanced imaging modalities. The aim of this review is to provide an up-to-date overview of the role of molecular imaging for the diagnosis of cardiac sarcoidosis, with particular emphasis on the use of FDG and non-FDG PET.Recent FindingsIn the last few years, FDG-PET has established itself as an accurate imaging study for the assessment of CS. New diagnostic criteria have recently appeared which incorporate FDG-PET findings in the diagnostic workup for CS. In addition, a joint SNMMI-ASNC Expert Consensus document has appeared on the role of FDG-PET in CS. Recent advances in the field have focused on the role of PET for diagnosis, assessment of therapy, and use of non-FDG tracers to image myocardial inflammation.SummaryThe role of PET is rapidly evolving but is now firmly established as an important component in the imaging assessment of CS.
