The modality 18-F-FDG-PET has been shown to be useful in monitoring disease activity and response to treatment in preliminary studies. The presence or absence of FDG uptake correlates well with a patient’s clinical state and MRI findings. Its use in patients with Takayasu arteritis requires further investigation.

Several studies have shown that whole-body PET scanning demonstrates anatomic changes consistent with the diagnosis of Takayasu arteritis. [35, 34, 33]
