目的对CT检查早期诊断强直性脊柱炎的诊断价值进行临床分析与探讨。方法将本院在近年来收治的早期诊断为强直性脊柱炎的患者共计15例作为研究对象,全部的患者均使用X线检查和CT进行检查,全部的患者均行骨盆平片与骶髂关节的CT检查,分析探讨检查的结果。结果有1例的X线检查结果为0级,CT检查结果为1级;有5例患者的X线检查结果为1级,CT的检查结果为2级;有4例患者的X线检查结果为2级,CT检查结果为3级;有1例患者的X线检查结果为3级,CT检查结果为4级。有4例患者的X线检查结果为正常或者是可疑的应用CT扫描,其中2例可确诊,诊断率提高了50%。4例CT检查比X线检查敏感一个级别,并且具有较高的特异性,敏感率提升了34%。结合临床患者的病史与实验室检查的结果,X线可确诊的为85%;CT可确诊的达100%。X线漏诊率为15%。结论骶骼关节的X线检查能够早期诊断强直性脊柱炎的存在,是早期进行诊断的简便的方法,骶髂关节CT检查能够显著的提高强直性脊柱炎早期诊断的几率,值得在临床中应用推广。
Objective To analyze and discuss the diagnostic value of CT in the early diagnosis of ankylosing spondylitis. Methods A total of 15 patients with early diagnosis of ankylosing spondylitis in our hospital in recent years were enrolled in this study. All patients were examined by X-ray and CT. All patients underwent pelvic plain and sacroiliac joint The CT examination, analysis and examination of the results. Results One patient had a grade 0 X-ray and a grade 1 CT. Five patients had a grade 1 X-ray and a grade 2 CT. There were 4 patients with X-ray findings Grade 2 and CT grade 3; one patient had a grade 3 X-ray and a grade 4 CT. Four patients had normal or suspected X-ray findings using CT scans, two of which were diagnosed and the diagnosis increased by 50%. 4 cases of CT examination than the X-ray examination sensitive to a level, and has a high specificity, the sensitivity rate increased 34%. Combined with the clinical history of patients and laboratory tests, the X-ray was diagnosed as 85%; CT can be diagnosed up to 100%. The rate of X-ray misdiagnosis was 15%. Conclusions X-ray examination of sacroiliac joint can diagnose ankylosing spondylitis early and is a simple and convenient method for early diagnosis. Sacroiliac joint CT examination can significantly improve the early diagnosis of ankylosing spondylitis, which is worthy of clinical application Promotion.
