Patient with CS. 18F-FDG PET/CT images were rated as inconclusive due to insufficiently suppressed physiological 18F-FDG uptake. Left panel: MIPs showing 18F-FDG PET/CT (upper) and 68Ga-DOTANOC PET/CT (lower) of patient no. 3. 68Ga-DOTANOC accumulation can be seen in the anterior and lateral wall (red arrow). Right upper panel: transaxial slices of 18F-FDG showing focal on diffuse 18F-FDG uptake considered inconclusive by a majority of readers. Right lower panel: 68Ga-DOTANOC accumulation (yellow arrow) is seen in the anterolateral and lateral wall (SUVmax 2.35, target-to-background 1.56). In the coronal view, it is evident that spill-in activity from the liver may obscure inferior lesions
