强直性脊柱炎骶髂关节MRI表现与炎症活动的相关性

Correlation between MR appearances of sacroiliac joint and inflammation activity in ankylosing spondylitis

目的探讨强直性脊柱炎(AS)骶髂关节MR检查SPARCC评分与临床BASDAI评分之间的关系。方法 对40例临床确诊为AS的患者进行骶髂关节MR扫描,并对其进行SPARCC评分。按照临床BASDAI评分分为静止期及活动期两组,对两组间SPARCC评分的差异进行比较,并对SPARCC评分与BASDAI评分之间的关系进行相关性分析。结果 两组间的SPARCC评分差异有统计学意义(P<0.05)。SPARCC评分与BASDAI评分之间呈正相关(r=0.39,P=0.014)。结论 在评估AS骶髂关节炎症活动中,SPARCC评分与临床BASDAI评分呈正相关。

Objective To analyze the correlation between the Spondyloarthritis Research Consortium of Canada（SPARCC） score of MRI in ankylosing spondylitis（AS） and clinical bath ankylosing spondylitis disease activity index（BASDAI） score.Methods Forty patients with AS confirmed clinically were included.All the patients underwent sacroiliac joint MR examination,and then were evaluated using SPARCC score.According to the BASDAI score,the patients were divided into two groups：Static group and active group.Comparative analysis was done between two groups.Results There was statistical difference of SPARCC score between the two groups（P0.05）.Spearman correlation coefficient between SPARCC score and BASDAI score was 0.39（P=0.014）.Conclusion In evaluating the activity in sacroiliitis of AS,SPARCC score of sacroiliac joints is positively correlated with the clinical BASDAI score.
