【摘 要】目的:探讨分析磁共振在诊断强直性脊柱炎骶髂关节病变方面是否优于多层螺旋CT(multi-slice spiral CT, MSCT)。方法:将84例强直性脊柱炎骶髂关节病变患者选作研究对象,所有病例均行磁共振和多层螺旋CT检查。主要观察关节面侵蚀、关节间隙改变、关节面下囊变、关节面增生硬化、腰5骶1关节突改变、软组织肿胀等指标,并对比两种影像检查方法检出率的差异指标。结果:在84例强直性脊柱炎骶髂关节病变中,MRI显示50(59.5%)关节面侵蚀,44(52.30%)显示关节面下囊肿,39(46.40%)显示关节面增生硬化,54(64.29%)显示关节间隙改变,53(63.10%)显示腰5骶1关节突关节改变,56(66.7%)显示软组织肿胀。MSCT显示 29(34.5%) 关节面侵蚀,29(34.5%)显示关节面下囊变,22(26.1%)关节面硬化,39(46.4%)显示关节间隙改变,37(44.0%)显示腰5骶1关节突关节病变,33(39.29%)显示软组织肿胀.MRI检出率均高于MSCT,差异有统计学意义(P <0.05).磁共振(MRI)平扫关节面侵蚀、关节间隙改变、关节面下囊变、关节面增生硬化、腰5骶1关节突改变、软组织肿胀方面高于多层螺旋CT,统计学有差异(P<0.05)。结论:诊断强直性脊柱炎,MRI平扫优于多层螺旋CT,应作为强直性脊柱炎骶髂关节病变的首选检查方法。

Abstract Objective:To study is MRI superior to MSCT in the diagnosis of ankylosing spondylitis in sacroiliac joint.Methods : 84 patients with ankylosing spondylitis with sacroiliac joint involved were selected.All of patients were undergone MRI examination and MSCT examination.The key point of observation was articular face and joint space and subchondral cyst and articular facet sclerosis and lumbar 5 sacral 1 facet joint as well as swelling of the soft tissue.To compare the difference of detection rate of ankylosing spondylitis in sacroiliac joint between MRI and MSCT.Results:In 84 cases, according to MRI findings,50(59.5%) showed articular face was affected,44(52.30%)showed subchondral cyst,39(46.40%) showed articular facet sclerosis,54(64.29%) showed the change of joint space,53(63.10%)showed the change of lumbar 5 sacral 1 facet joint,56(66.70%) showed swelling of the soft tissue. According to MSCT signs,29(34.5%) showed articular face was affected,29(34.5%)showed subchondral cyst,22(26.1%) showed articular facet sclerosis,39(46.4%) showed the change of joint space,37(44.0%)showed the change of lumbar 5 sacral 1 facet joint,33(39.29%) showed swelling of the soft tissue. Detection rate of MRI are all higher than that of MSCT,a statistically significant difference was detected (P <0.05). Conclusion: MRI is superior to MSCT in the diagnosis of ankylosing spondylitis in sacroiliac joint,and MRI shouled be regarded as the first choice of imaging procedure.

强直性脊柱炎(Ankylosing Spondyliris,AS)疾病,是一种较为典型的以血清学检查结果阴性为基本特征的人体脊柱关节组织疾病形态,是一种发生于患者全身的慢性免疫性结缔组织疾病,且患者机体的中轴关节组织结构通常作为最具代表性的病理组织结构分布区域[1]。在强直性脊柱炎疾病患者临床病程的早期发展阶段,患者通常展现出的最为主要的临床症状,是发生于骶髂关节组织结构之中的结构性或者是功能性病理改变,且在此基础上通常会不可避免地诱导患者发生机体脊柱组织结构的强直性或者是畸形性病变现象[2-3]。……
