1 Fig. 2. Arterial fluorodeoxyglucose (FDG) uptake related to atherosclerosis. On positron emission tomography (PET) coronal (A), PET/CT fusion coronal (B), and transaxial (C) images of 68-year-old man, focal increased FDG uptake is observed in right brachiocephalic artery (arrows). Increased FDG uptake is often incidentally observed in major arteries during diagnostic workup for cancer. FDG uptake is sometimes very strong, whereas FDG uptake is also observed in other arteries to certain degree (arrowhead). Fig. 2. Arterial fluorodeoxyglucose (FDG) uptake related to atherosclerosis.
