The SUVs were significantly correlated with age in OA. With increasing age, the Mean SUV of the knee joint increased independently of the presence of joint problems (A, B). The joint-SUVmean and intra-articular SUVmax showed significant positive correlation with age (C, D), even in the group without OA symptoms (E, F) and without evidence of radiographic OA (G, H). The SUVs adjusted for age and gender showed remarkable and significant correlations, especially in females (I, J).
