摘　　要：目的探讨CT和MRI对强直性脊柱炎骶髂关节病变的诊断价值。方法对80例强直性脊柱炎骶髂关节病变患者均采用螺旋CT和MRI影像检测诊断，比较两种诊断的影像表现和诊断结果。结果CT影像Ⅰ级诊断率为27．5％，显著低于MRI影像Ⅰ级诊断率（42．5％），差异有显著性（χ2=3．96，P〈0．05）；影像0、Ⅱ、Ⅲ、Ⅳ级诊断率与MRI诊断结果比较差异均无显著性（P〉0．05）。结论CT和MRI均为强直性脊柱炎骶髂关节病变的有效诊断方法，二者各有其特点和不足，但MRI更适合早期诊断。Objective To explore CT and MRI diagnostic value for sacroiliac joint lesions in ankylosing spondylitis （SJLAS）. Methods Eighty SJLAS patients were all diagnosed using spiral CT and MRI, ima- ging manifestations and diagnostic results compared between 2 examinations. Results Class Ⅰ CT diagno- sis rate was 27.5% and significantly lower than MRI （42.5%） （χ2 =3.96,P〈0.05） ; there were no signif- icant differences in class 0, Ⅱ, Ⅲ and Ⅳ diagnosis rate between CT and MRI （P〉0.05）. Conclusion Both CT and MRI are effective diagnosis methods for SJLAS and have characteristics and insufficiencies, but MRI is more suitable for early diagnosis.
