Qualitative Summary Score of Global Arterial FDG Uptake (PETVAS). A, Mean qualitative scores by arterial region in patients with large vessel vasculitis (LVV) versus a composite disease comparator group. B, Comparison of mean summary score of FDG uptake in 9 arterial territories (PETVAS) in patients with a PET scan interpreted as inactive versus active vasculitis. C, Comparison of PETVAS in patients with giant cell arteritis (GCA), Takayasu’s arteritis (TAK), and disease comparator groups. D, Comparison of PETVAS in patients with GCA and TAK stratified by clinically determined disease activity status. E, Receiver Operating Characteristic Curve of the performance characteristics of PETVAS to differentiate clinically active LVV from LVV in clinical remission. Results in A and B are analyzed by two-tailed student t test. Results in C and D are presented as means with standard error margin and analyzed by one-way ANOVA with post hoc Tukey’s multiple comparison’s test. * p <0.05; ** p<0.01; *** p<0.001; **** p<0.0001. ns = not significant.
