A dual tracer 68Ga-DOTANOC PET/CT and 18F-FDG PET/CT pilot study for detection of cardiac sarcoidosis

19 patients (12 male, 7 female) with suspected cardiac sarcoidosis, median age 54 years (range 33-67).

68Ga-DOTANOC PET/CT (3 MBq/kg, acquired 90 minutes post-injection)

18F-FDG PET/CT (4 MBq/kg, acquired 60 minutes post-injection, following ~15 hours of fasting)

Diagnostic accuracy (sensitivity, specificity, PPV, NPV) and inter-observer variability (Fleiss' kappa) for detecting cardiac sarcoidosis compared to the Japanese Ministry of Health and Welfare (JMHW) reference standard.surrogate
