X射线、CT与MRI在早期强直性脊柱炎诊断中的应用

Application of X-Ray,CT and MRI in the Diagnosis of Early Ankylosing Spondylitis

目的:对诊断早期强直性脊柱炎中引入X射线、CT与MRI的临床价值进行系统研究与探讨,以不断提高临床诊断准确率。方法:选择本院2018年11月~2019年11月收治的120例早期强直性脊柱炎患者作为实验对象,随机数字表法分组后探究每组诊断效果。X射线组(40例):应用X射线诊断;CT组(40例):应用CT诊断;MRI组(40例):应用MRI诊断。分析影像学表现,对比三组患者检出率、诊断结果。结果:MRI组临床检出率为95%(38/40),高于X射线组(75%,30/40)、CT组(50%,20/40),临床对比存在统计学差异(P<0.05);MRI组检出关节间隙狭窄、关节面侵蚀、关节面软骨肿胀、关节间隙增大、关节面下骨质硬化率分别为30%(12/40)、40%(16/40)、50%(20/40)、55%(22/40)、60%(24/40),均高于X射线、CT组,临床比较差异性显著(P<0.05)。结论:早期强直性脊柱炎临床诊断选用MRI诊断方法,效果优于X射线和CT诊断。

Objective:To study and discuss the clinical value of X-ray,CT and MRI in the diagnosis of early ankylosing spondylitis so as to improve the accuracy of clinical diagnosis.Methods:120 patients with early ankylosing spondylitis admitted to our hospital from November 2018 to November 2019 were selected as the experimental subjects,and the diagnosis effect of each group was explored after grouping by random digital table.X-ray group(40 cases):X-ray diagnosis;CT group(40 cases):CT diagnosis;MRI group(40 cases):MRI diagnosis.The imaging findings were analyzed,and the detection rate and diagnosis results of the three groups were compared.Results:The clinical detection rate of MRI group was 95%(38/40),higher than that of X-ray group(75%,30/40)and CT group(50%,20/40),and there was statistical difference in clinical comparison(P<0.05);the detection rates of joint space stenosis,joint surface erosion,articular surface cartilage swelling,joint space enlargement and joint subsurface osteosclerosis in MRI group were 30%(12/40),40%(16/40),50%(20/40)and 55%(22/40)and 60%(24/40)were higher than that of X-ray and CT group,and the clinical difference was significant(P<0.05).Conclusion:MRI is better than X-ray and CT in the diagnosis of early ankylosing spondylitis.
