CT诊断强直性脊柱炎骶髂关节病变及评价关节损伤程度的效果研究

Effect Study on CT in Diagnosis of Sacroiliac Joint Disorder in Ankylosing Spondylitis and in Evaluation of Joint Damage Degree

目的探讨CT检查在强直性脊柱炎骶髂关节病变诊断中价值。方法选取2014年1月至2017年12月在我院治疗的强直性脊柱炎患者80例,所有患者均行CT和X线检查。结果 CT检查对强直性脊柱炎检出率为70.00%,明显高于X线检查,,差异有统计学意义(P<0.05);CT检查对关节侵蚀、关节面下骨质囊变检出率分别为41.25%和40.00%,明显高于X线,差异有统计学意义(P<0.05);CT检查和X线检查对关节面增生硬化、关节间隙增宽或狭窄和关节面融合检出率比较差异无统计学意义(P>0.05);CT对强直性脊柱炎骶髂关节病变分级明显高于X线检查差异有统计学意义(P<0.05)。结论 CT检查在强直性脊柱炎骶髂关节病变诊断中有较好的应用价值,值得临床使用。

Objective To investigate the value of CT examination in the diagnosis of sacroiliac joint disorder in ankylosing spondylitis.Methods 80 patients with ankylosing spondylitis treated in our hospital from January 2014 to December 2017 were enrolled.All patients underwent CT and X-ray examination.Results Detection rate of ankylosing spondylitis of CT examinationwas 70.00%,which was significantly higher than that of X-ray examination,with statistically significant difference(P<0.05);Detection rates of joint erosion and cystic changes of boneunder articular surfacewere 41.25%and 40.00%,respectively,which were significantly higher than those in X-ray examination,with statistically significant differences(P<0.05).There were no significant differences in detection rates of hyperplasia and sclerosis of articular surface,widening or stenosis of joint space and fusionof articular surface between CT examination and X-ray examination(P>0.05).The grade of sacroiliac joint disorder in ankylosing spondylitisof CT examinationwas significantly higher than that of X-ray examination,with statistically significant differences(P<0.05).Conclusion CT examination has a good application value in the diagnosis of sacroiliac joint disorder in ankylosing spondylitis,which deserves clinical promotion.
