目的 探讨磁共振成像检查对 骶髂关节炎的应用价值分析研究价值。 方法 收集2013年11月-2014年11月以骶 髂关节炎症状入我院的患者98例，通过 磁共振成像检查分析磁共振对骶髂关节 炎的确诊率、磁共振成像技术对骶髂关 节炎检查的运用，分析磁共振成像检 查对骶髂关节炎的应用价值。结果 经 MRI扫描诊断为骶髂关节炎症的患者95 例，MRI扫描对骶髂关节炎症的确诊率为 96.94%(95/98)，其中包括骨关节面变粗 糙紊乱42例(44.21%)，关节骨质破坏增 生硬化15例(15.79%)，囊性改变变17例 (17.89%)，关节融合11例（11.57%）， 关节腔隙变窄10例(10.52%）。MRI成像 技术对骶髂关节炎成像显影清楚，病灶 强化直观，对病灶活动期提示准确。结 论 MRI扫描对骶髂关节炎早期的确诊率 高，关节腔内病变显示清楚，与周围组 织解剖关系直观明了，为临床治疗提供 了良好的影像学资料。

Objective To investigate the application value analysis of magnetic resonance imaging on sacroiliitis. Methods 98 cases with sacroiliitis in our hospital from November 2013 to November 2014 were selected. Analyze the diagnosis rate, role and application value of magnetic resonance imaging on sacroiliitis. Results There were 95 cases diagnosed to besacroiliitis by MRI, diagnosis rate was 96.94%(95/98), including 42 rough and disorder bony articular surface (44.21%), 15 (15.79%) joint bonehyperostosis osteosclerosis, 17 cystic changes (17.89%), 11 joint fusion (11.57%), 10 lacuna narrowing (10.52%). Magnetic resonance imaging had accurate prompt on lesions activity. Conclusion MRI has higher positive rate on sacroiliitis and can show clearly the lesions in articular cavity, it can provide better imaging materials for clinic treatment.
