目的比较早期强直性脊柱炎骶髂关节病变的X线、CT和MRI的诊断价值。方法在本院确诊的168例早期强直性脊柱炎骶髂关节病变患者作为研究对象,回顾性分析患者的X线、CT和MRI检查结果。结果 X线检出率为73.2%,CT检出率为86.9%,MRI检出率为100%,组间两两比较均有显著性差异(均P<0.01),MRI检出率显著高于CT和X线检出率,CT检出率显著高于X线检出率。结论 MRI可以较好的弥补X线和CT的缺陷,不仅具有更高的诊断价值,还具有一定的治疗指导价值,对于早期强直性脊柱炎骶髂关节病变来说,可以作为优先考虑的诊断方式。
Objective To compare the diagnostic value of X-ray, CT and MRI in sacroiliac joint lesions of ankylosing spondylitis. Methods A total of 168 patients with ankylosing spondylitis and sacroiliac joint disease diagnosed in our hospital were studied. The results of X-ray, CT and MRI were retrospectively analyzed. Results The detection rate of X-ray was 73.2%, the detection rate of CT was 86.9% and the detection rate of MRI was 100% (all P <0.01). The detection rate of MRI was significantly higher than that of MRI CT and X-ray detection rate, CT detection rate was significantly higher than the X-ray detection rate. Conclusion MRI can make up for the defects of X-ray and CT, not only have higher diagnostic value, but also have certain therapeutic value. For the patients with ankylosing spondylitis, sacroiliac joint disease can be regarded as the first diagnosis .
