FDG uptake parameters of the ascending aorta for the two clinical response groups. The mean SUVmax and TBR values of the ascending aorta at 6 months after biologic treatment were significantly higher in the group with a DAS28-ESR < 3.2 (indicating remission or low disease activity) than in the group with a DAS28-ESR ≥ 3.2 (indicating moderate or high disease activity). SUVmax, maximum standardized uptake value; TBR, target-to-background ratio; DAS28, Disease Activity Score in 28 joints; RLDA, remission or low disease activity; MHDA, moderate or high disease activity
