MRI和X线在强直性脊柱炎骶髂关节病变的诊断价值研究

MRI and X-ray in the Diagnosis of Sacroiliac Joint Disease Ankylosing Spondylitis Value Research

目的探讨MRI和X线在强直性脊柱炎骶髂关节病变早期诊断中的临床价值。方法选取2015年6月至2016年8月我院收治的确诊为强直性脊柱炎骶髂关节病变患者92例为研究对象,分别对入选患者进行MRI和X线影像学检查,对比两种检查方法对患者病变的检出情况及对病变分级的诊断情况。结果 MRI诊断强直性脊柱炎骶髂关节病变的检出率为100.00%,X线的检出率为80.43%,MRI的检出率明显高于X线的检出率(P<0.05);与X线检查对比,MRI对Ⅰ级强直性脊柱炎骶髂关节病变的检出率明显升高,对0级的诊断准确率也明显高于X线检查(P<0.05),其他分级未见明显差异(P>0.05);与X线检查相比,MRI影像学检查对强直性脊柱炎骶髂关节面侵袭、关节面骨质囊变、关节软骨肿胀及关节间隙变窄的检出率明显升高(P<0.05)。结论 MRI在诊断强直性脊柱炎骶髂关节病变具有较高的检出率,也能较好的显示出病变情况,具有较高的临床价值。

Objective To investigate the clinical value of MRI and X-ray in the early diagnosis of sacroiliac joint lesions in ankylosing spondylitis.Methods Selection in June 2015 to August 2016,our hospital diagnosed with ankylosing spondylitis patients with sacroiliac joint lesions in 92 cases as the research object,respectively for selected patients with MRI and X-ray imaging examination,compared to two kinds of checking methods for the detection of patients with lesions and the diagnosis of lesions in grading.Results The detection of MRI in the diagnosis of sacroiliac joint in ankylosing spondylitis rate was 100%,the X-ray detection rate was 80.43%,the detection rate of MRI was significantly higher than that of X-ray(P<0.05),compared with X-ray,MRI grade of sacroiliac joint in ankylosing spondylitis detection rate increased significantly,the 0 level of accurate diagnosis the rate was significantly higher than that of X-ray(P<0.05),other classification showed no significant difference(P>0.05).Compared with the X-ray and MRI imaging on invasion of ankylosing spondylitis sacroiliac joints,joint bone mass and cystic change of articular cartilage and joint swelling The detection rate of gap narrowing was significantly higher(P<0.05).Conclusion MRI in the diagnosis of ankylosing spondylitis sacroiliac joint lesions with a higher detection rate,but also can better show the lesions,with high clinical value.
