目的：研究多层螺旋CT在强直性脊柱炎骶髂关节病变临床诊断中的应用价值。方法选取我院104例患有强直性脊柱炎骶髂关节病变的患者，于规定时间内分别使用X线平片和螺旋CT对所有患者的病变情况进行检查。结果(1)在Ⅰ级和Ⅱ级强直性脊柱炎骶髂关节病变的检出中，多层螺旋CT的检出率高于X线平片，差异有统计学意义(P<0.05)；对于Ⅲ级和Ⅳ级病变的检出，两者差异则无统计学意义(P>0.05)。(2)螺旋CT检查出关节面侵蚀、关节面下骨质囊变、骨质增生硬化和软组织肿胀的患者明显多于X线平片，其差异具有统计学意义(P<0.05)；而对关节间隙狭窄或增宽和关节强直的检查结果进行比较，两者差异均无统计学意义(P>0.05)。结论在强直性脊柱炎骶髂关节多种病变的检查中，多层螺旋CT都显现出了较高的有效性。

Objective To study the availability of multislice spiral CT in diagnosing sacroiliac joint disorder with ankylosing spondylitis. Methods One hundred and fifty patients with ankylosing spondylitis in sacroiliac joint were chosen and underwent multislice spiral CT and X-ray examination within the prescriptive time. Results (1) The detection rates of level ⅠandⅡ lesions in sacroiliac joint with ankylosing spondylitis by multislice spiral CT were higher than those by X-ray with a statistical difference (P<0.05). However, there was no difference between multislice spiral CT and X-ray in detecting levelⅢandⅣlesions (P>0.05). (2) Patients with bone cysts beneath the joint sur-face, osteoproliferation sclerosis and soft tissue swelling detected by multislice spiral CT were more than those by X-ray with a statistical difference (P<0.05). Conclusion In the diagnosis of ankylosing spondylitis in sacroiliac joint, multislice spiral CT showed good effectiveness.
