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

Typical 18F-FDG PET/CT false positive for cardiac sarcoidosis. Left panel: maximum intensity projections (MIPs) of patient no. 14. scanned after injection of ~370 MBq 18F-FDG and ~300 MBq 68Ga-DOTANOC. Red arrows denote 18F-FDG uptake in hilar lymph nodes (sarcoidosis). The hilar sarcoidosis is clearly visible on both 18F-FDG PET and 68Ga-DOTANOC PET. Right panel: transaxial slices of the cardiac region with 18F-FDG (top) uptake in the basal lateral wall of the myocardium (SUVmax 7.4). 68Ga-DOTANOC (bottom) images show uniform activity in the entire cardiac region (myocardium and blood pool) with no areas of focal uptake effectively ruling out CS. Notice the different SUV scales for the two radiotracers
