Large-Vessel Vasculitis: Interobserver Agreement and Diagnostic Accuracy of ¹⁸F-FDG-PET/CT

Figure 1

¹⁸F-FDG PET/CT scans showing: (a) Maximum intensity projection (MIP) image: scored as large-vessel vasculitis by all observers according to all methods, (b) coronal image: ¹⁸F-FDG uptake in descending aorta (arrow) scored as equal to liver uptake (arrowhead) by 2 observers and lower than liver uptake by 2 other observers, none of the observers scored higher than liver or femoral artery uptake, (c) MIP image of a PMR patient that was scored negative for large-vessel vasculitis by all observers. (Cerebral and urinary tract 18-¹⁸F-FDG uptake are physiological).
