摘　　要：目的:探讨螺旋CT在强直性脊柱炎骶髂关节病变诊断中的临床应用价值。方法:选择强直性脊柱炎骶髂关节病变患者99例,所有患者均接受普通X线平片及多层螺旋CT检查。比较两者对疾病的分期及对各种征象的显示情况。结果:1.螺旋CT对Ⅰ级和Ⅱ级病变的检出率显著高于X线平片,其差异有统计学意义(P<0.05)。在Ⅲ级和Ⅳ级病变的检出中,两种检查方法无统计学差异(P>0.05)。2.螺旋CT对关节面侵蚀、关节面下骨质囊变、腰5骶1关节突病变及软组织肿胀的显示率均显著高于X线平片(P<0.05)。在对关节增生硬化、关节间隙增宽或狭窄、关节强直的显示中,两种检查方法无统计学差异(P>0.05)。结论:螺旋CT在强直性脊柱炎骶髂关节病变诊断中具有很高的应用价值。Objective.To investigate the clinical value of spiral CT in the diagnosis of sacroiliac joint lesion in ankylosing spondylitis. Methods：A total of 99 patients with sacroiliac joints lesion in ankylosing spondylitis were chosen, all patients underwent X-ray and spiral CT examination within 3 days after ad- mission. The images were observed and compared among patients with different stage and different signs. Results：The detection rate of Spiral CT of class I and class II lesions was significantly higher than the X- ray film, the difference was statistically significant （P^0.05）. For the detection of grade III and IV grade lesions, the two methods had no significant difference （P〈0.05）. Spiral CT had significantly higher de- tection rate than the X-ray plain film in detecting articular surface erosion, articular surface of the bone cystic degeneration, L5/S1 the zygapophysial lesions and soft tissue swelling （P〈0. 05）. But the differ-ence was not significant in detecting joint hyperplasia, sclerosis, joint space widening or narrow, and joint stiffness difference （P^0.05）. Conclusions： Spiral CT is valuable in the diagnosis of sacroiliac joints lesion in ankylosing spondylitis.
