目的:探讨全身MRI在强直性脊柱炎(AS)活动性炎症中的评估价值。方法:对96例经临床确诊的AS患者进行全身MRI扫描,评估活动性炎症累及的部位(主要包括骶髂关节、脊柱及肩关节、髋关节等外周大关节,共计23个部位),并采用加拿大脊柱关节炎...目的:探讨全身MRI在强直性脊柱炎(AS)活动性炎症中的评估价值。方法:对96例经临床确诊的AS患者进行全身MRI扫描,评估活动性炎症累及的部位(主要包括骶髂关节、脊柱及肩关节、髋关节等外周大关节,共计23个部位),并采用加拿大脊柱关节炎研究协会(SPARCC)评分方法对脊柱和骶髂关节炎症进行评分。采用卡方检验或Fisher精确检验(频数小于5时)比较短病程(病程<5年)组(41例)和长病程(病程≥5年)组(55例)之间各部位活动性炎症的受累率,采用t检验比较两组患者SPARCC评分的差异。采用单因素分析确定两组之间活动性炎症发生率具有差异的部位后,采用二元logistic回归分析筛选出与长病程显著相关的受累部位。结果:短病程组中活动性骶髂关节炎的发生率明显高于长病程组(44/82 vs. 37/110,P<0.05);椎角炎、椎小关节炎、肋横突关节炎、股骨大转子附着点炎、棘突附着点炎、胸肋关节炎、耻骨联合炎、髂后上棘及耻骨下支附着点炎在长病程组中的发生率均高于短病程组(P<0.05)。短病程组的骶髂关节SPARCC评分明显高于长病程组(11.220±12.817 vs. 3.854±7.327,P<0.05),脊柱SPARCC评分明显低于长病程组(7.584±7.635 vs. 16.098±13.225,P<0.05)。二元logistic回归分析结果显示骶髂关节炎(OR=0.322,P=0.002)、耻骨联合炎(OR=5.045,P=0.025)和脊柱SPARCC评分(OR=1.102,P=0.002)与长病程具有显著相关性。结论:全身磁共振成像可以全面评估强直性脊柱炎患者活动性炎症的分布情况。病程早期骶髂关节活动性炎症较明显,而慢性期更易出现脊柱、其它周围关节及肌腱附着点的活动性炎症。展开更多
