[ 18 F]Fluorodeoxyglucose positron emission tomography (FDG PET) can be used to visualize large‐vessel inflammation in giant‐cell arteritis, Takayasu arteritis, and other types of aortitis. In patients with symptoms compatible with polymyalgia rheumatica, findings of increased FDG‐uptake in the shoulders, hips, as well as the spinous processes of the cervical and lumbar spine, may suggest this diagnosis. In patients with giant‐cell arteritis, there is increased metabolic activity within the aortic wall on FDG PET scintigraphy, indicating inflammation of the aorta, which may be a predictor of a higher potential for aortic dilatation.
