CT、X线平片及MRI平扫在强直性脊柱炎骶髂关节病变诊断中的临床应用

Clinical application of CT,X-ray and MRI in the diagnosis of sacroiliac joint disease of ankylosing spondylitis

目的探讨CT、X线平片及MRI平扫在强直性脊柱炎骶髂关节病变诊断中的临床应用价值。方法选取2014年12月~2017年3月在我院就诊检查的81例强直性脊柱炎骶髂关节病变患者,随机分为甲组、乙组、丙组,各27例。甲组采用X线平片检查,乙组给予MRI成像检查,丙组则给予64排螺旋CT扫描检查,观察3种检查方式的诊断效果及图像质量。结果乙组与丙组各项临床特征的检出率显著高于甲组,差异有统计学意义(P<0.05)。乙组与丙组各项临床特征的检出率比较,差异无统计学意义(P>0.05)。乙组和丙组的分级诊断准确性高于甲组,差异有统计学意义(P<0.05)。结论 CT与MRI平扫在强直性脊柱炎骶髂关节病变患者中的诊断准确性显著高于X线平片检查,主要的临床特征为关节肿胀、骨质囊变、骨质疏松及关节面被侵蚀等,且各项检查操作简单方便,具有一定的准确性和可行性,值得临床推广应用。

Objective To explore the clinical application value of CT,X-ray and MRI in the diagnosis of sacroiliac joint disease in ankylosing spondylitis.nethods From December 2014 to March 2017,81 cases of sacroiliac joint disease in ankylosing spondylitis in our hospital were selected and randomly divided into group A,group B,group C,27 cases in each group.Group A was examined by X-ray examination,group B was given MRI imaging,group C was given 64-slice spiral CT scan.The diagnostic effect and image quality of the three methods were observed.Results The detection rate of clinical features of group B and group C was significantly higher than that of group A,with significant difference （P〈 0.05）.There were no significant differences in the detection rates of clinical features between group B and group C （P〉0.05）.The diagnostic accuracy of classification of group B and group C was higher than that in group A,with significant difference （P〈0.05）.Conclusion The accuracy of CT and MRI examination in patients with ankylosing spondylitis and sacroiliac joint disease is significantly higher than that of X-ray examination,the main clinical features were joint swelling,osteoarthritis,osteoporosis and articular surface Erosion and so on,and the inspection operation is simple and convenient,with a certain accuracy and feasibility,it is worthy of clinical promotion and application.
