PET/CT fusion images with either FDG or FAMT administration for the same patients with NET or CAR. For a patient with NET, FDG PET images showed high spotty accumulations (arrow) in the liver (a). No FAMT uptakes were seen in the liver (b). For a patient with CAR, FDG PET showed diffuse uptake for normal liver parenchyma without uptakes for tumor lesion in the liver (c). FAMT PET showed some faint massive uptakes (arrow) of FAMT in the liver (d). FDG 2-[18F]-fluoro-2-deoxyglucose, FAMT L-3-[18F] fluoro-alpha-methyl tyrosine, T/L tumor-to-liver parenchymal, CAR carcinoid tumor, NET neuroendocrine tumor and pheochromocytoma
