Cardiac sarcoidosis (CS) is difficult to clinically diagnose but associated with high morbidity and mortality. Hybrid PET/MR has been shown to provide clinicians with complementary data regarding both the pattern and activity of myocardial disease. We performed a segmental quantitative analysis of MR parameters on 30 patients including T1 and T2 mapping, ECV, scar and strain acquired as part of a hybrid PET/MR study to evaluate characteristic patterns of imaging in this heterogeneous disease process. Scar quantification had a significant positive correlation with T1 and ECV and was negatively correlated with strain.
