目的研究临床症状、实验室检查、MRI测量是否能够区分青少年先天性关节炎(JIA)及其他儿童活动性关节炎。方法回顾性分析了80例临床怀疑JIA并经治疗后的病例资料,所有病人至少有1个膝关节受累且为12个月以内的活动性非感染性关节炎。对病人进行临床和实验室评估以及对比增强MRI检查。MRI不作为诊断标准。结果 44例(55%)病人临床诊断为JIA,而36例(45%)经临床和实验室检查不能诊断为JIA。27例(61.4%)JIA病人和7例(19.4%)非JIA病人经MRI诊断为滑膜炎。5个因素(男性、经医生全
Objective To investigate whether clinical symptoms, laboratory tests and MRI can distinguish active juvenile arthritis (JIA) from other active arthritis in children. Methods A retrospective analysis of 80 cases of clinical suspected JIA and after treatment of the case data, all patients involved in at least one knee joint involvement and active non-infectious arthritis within 12 months. Clinical and laboratory assessments of patients and contrast-enhanced MRI were performed. MRI is not used as a diagnostic standard. Results Forty-four (55%) patients were clinically diagnosed as JIA and 36 (45%) were clinically and lab-less diagnosed as JIA. 27 (61.4%) JIA patients and 7 (19.4%) non-JIA patients were diagnosed with synovitis by MRI.
