探讨强直性脊柱炎骶髂关节病变早期的影像学诊断价值

目的：探讨三种影像学检查方法在早期强直性脊柱炎骶髂关节病变诊断中的价值分析.方法：选取2011年1月-2015年1月我院收治的早期强直性脊柱炎骶髂关节病变患者120例作为研究对象,分别采用 X 线、CT 及 MRI 对上述患者进行扫描检查,对三种检查方法的影像学表现及分级情况进行观察比较.结果：在关节面侵蚀、关节面下骨质硬化及关节面骨质囊变方面,MRI 与 CT 诊断的检出率较 X 线诊断检出率明显升高,比较差异均具有显著性（P 〈0.05）.与 CT 检查比较,MRI 诊断关节面骨质囊变检出率明显升高,差异具有显著性（P 〈0.05）.与 X 线及 CT 诊断相比,MRI 在0级强直性脊柱炎检出率明显升高,比较差异均具有显著性（P 〈0.05）;在 Ⅰ 级、Ⅱ 级强直性脊柱炎检出率方面,与X线比较,MRI和CT诊断的检出率均明显提高,比较差异均具有显著性（P〈0.05）.结论：在早期强直性脊柱炎骶髂关节病变诊断中,X线、CT及MRI三种影像学方法均具有一定的诊断应用价值,其中与另外两种方法比较,MRI 方法对骨质异常病变及强直性脊柱炎分级病变能更准确的检出.

Objective： To study the three methods of imaging examination in the diagnosis of sacroiliac joint of ankylosing spondylitis in the early pathological changes value analysis.Methods： 120 patients with sacroiliac joint of ankylosing spondylitis in the early pathological changes were selected in our hospital from January 2011 to January 2015 as the research object, using X-ray, （P 〈 0.05）.Conclusion： The diagnosis of sacroiliac joint of ankylosing spondylitis in the early pathological changes, X-ray, CT and MRI of three imaging methods have certain diagnosis application value, compared with the other two methods, including abnormal MRI method of bone lesions and ankylosing spondylitis grading lesions can more accurate detection.
