Examination and conventional radiography of joints are unable to precisely evaluate and measure disease activity in rheumatoid arthritis (RA). We quantified joint inflammation using FDG PET-CT (¹⁸F-Fluorodeoxyglucose positron emission computed tomography) in people with RA to determine if PET-derived uptake parameters were correlated with RA disease activity measures.

关节 18 氟脱氧葡萄糖摄取与类风湿性关节炎患者的临床评估肿胀关节计数相关。

关节检查和常规 X 线摄影无法准确评估和测量类风湿性关节炎 (RA) 的疾病活动。^{我们使用 FDG PET-CT（ 18} F-氟脱氧葡萄糖正电子发射计算机断层扫描）对 RA 患者的关节炎症进行量化，以确定 PET 衍生的摄取参数是否与 RA 疾病活动指标相关。
