In a prospective case–control study recently published in the Annals of Rheumatic Diseases, Prieto-González et al1 have shown a high sensitivity and specificity of positron emission tomography (PET)/CT with 18fluorodeoxyglucose (FDG) in 32 patients with newly diagnosed, biopsy-proven giant cell arteritis (GCA). Using receiver–operator characteristic curves (ROC) analysis, the authors determined cut-off maximal standardised uptake values (SUVm) to detect vascular inflammation by PET/CT. The sensitivity and specificity of PET/CT obtained in this study was close to that calculated in a recent meta-analysis of mostly retrospective studies.2

We used PET with FDG for diagnosis and assessment of …
