摘要目的利用儿童膝关节对比增强MRI来研究无临床关节炎与临床活动性幼年特发性关节炎(JIA)增强的滑膜厚度;其次是优化两组之间基于MRI最大化差异的评分方法。方法纳入25例无关节疾病史或任何临床关节炎症指征的儿童;另一组为25例年龄及性别相匹配至少一侧膝关节
Abstract Objective To study the increased synovial thickness of non-clinical arthritis and clinically active juvenile idiopathic arthritis (JIA) using contrast-enhanced MRI of the knee in children. The second is to optimize the scoring method based on the maximum difference in MRI between the two groups. Methods Twenty-five children with no history of joint disease or any clinical signs of joint inflammation were enrolled in the study. The other group consisted of 25 age- and sex-matched at least one knee joint
