基于广义估计方程探讨三维MRI联合CT影像学检查对膝关节骨性关节炎关节病变的诊断价值

To Explore the Diagnostic Value of Three-dimensional MRI Combined with CT Imaging in Joint Lesions of Knee Osteoarthritis Based on Generalized Estimation Equation

目的探讨三维核磁共振成像(MRI)联合计算机断层扫描(CT)影像学检查对膝关节骨性关节炎关节病变、分期的诊断价值。方法 回顾性分析2019年9月至2022年9月我院收治的135例膝关节关节炎患者临床资料。比较不同成像方法与关节镜结果的一致性和诊断效能。分析不同成像方法与关节镜分期结果的相关性。比较不同影像学方法诊断关节病变的置信度。结果 三维MRI联合CT检查结果的一致性(Kappa=0.701)大于三维MRI (Kappa=0.512)或CT (Kappa=0.373)单独检查。联合检查的诊断准确率(85.93%)明显高于单独检查(77.04%、70.37%)。影像学分期结果与关节镜分期结果均呈正相关(r=0、801、0.766,P<0.01)。联合诊断关节病变的准确性及特异性明显高于单独诊断。结论 三维MRI联合CT影像学检查对膝关节骨性关节炎关节病变、分期的诊断具有较高的检出率和准确率。

Objective To explore the diagnostic value of three-dimensional MRI combined with CT imaging in the diagnosis and staging of knee osteoarthritis.Methods Retrospective analysis of the clinical data of 135 patients with knee arthritis admitted to our hospital from September 2019 to September 2022.Compared the consistency and diagnostic effectiveness of different imaging methods and arthroscopic results.Analyze the correlation between different imaging methods and arthroscopic staging results.Compared the confidence levels of different imaging methods in the diagnosis of joint diseases.Results The consistency of the results of three-dimensional MRI combined with CT(Kappa=0.701)was greater than that of three-dimensional MRI(Kappa=0.512)or CT(Kappa=0.373)alone.The diagnostic accuracy of combined examination(85.93%)was significantly higher than that of single examination(77.04%,70.37%).The imaging staging results were positively correlated with the arthroscopic staging results(r=0.801,0.766,P<0.01).The accuracy and specificity of combined diagnosis of joint diseases are significantly higher than that of single diagnosis.Conclusion Three-dimensional MRI combined with CT imaging has a high detection rate and accuracy in the diagnosis of knee osteoarthritis,joint lesions,and stages.
