Positron emission tomography assessment of large vessel inflammation in patients with newly diagnosed, biopsy-proven giant cell arteritis: a prospective, case–control study

Background

Positron emission tomography (PET) scan is emerging as a promising imaging technique to detect large-vessel inflammation in giant cell arteritis (GCA). However, the lack of a standardised definition of arteritis based on ¹⁸fluorodeoxyglucose (FDG) uptake is an important limitation to the use of PET scan for diagnostic purposes.

Objective

To prospectively assess the intensity and distribution of FDG uptake...
