摘　　要：目的探讨核磁共振成像对膝关节退行性骨关节病的诊断价值。方法选取2020年3月—2021年5月我院接收的疑似膝关节退行性骨关节病70例患者的影像检查资料进行回顾性研究。全部患者均接受核磁共振成像检查,以病理学检查结果作为金标准,分析核磁共振成像检查对不同病变类型的检出情况和诊断效能。结果检查70例疑似膝关节退行性骨关节病患者得出,核磁共振成像检查同时出现阴性和阳性2个结果,其中阳性52例,阴性18例,特别是关节间隙狭窄、关节边缘骨赘形成、关节腔内游离体的阳性检出率最高,均为17.31%。核磁共振成像检查诊断的敏感性为92.31%,特异性为88.89%,准确性为91.43%、阳性预测值为96.00%、阴性预测值为80.00%。结论核磁共振成像可有效判断膝关节退行性骨关节病的病变类型,提高临床诊断效能。Objective To explore the diagnostic value of MRI in knee degenerative osteoarthropathy.Methods A retrospective study was conducted on the imaging data of 70 patients with suspected knee degenerative osteoarthropathy admitted to our hospital from March 2020 to May 2021.All patients underwent MRI examinations,with pathological examination results used as the gold standard to analyze the detection and diagnostic efficacy of MRI for different types of lesions.Results Among the 70 patients with suspected knee degenerative osteoarthropathy,MRI detected 52 positive and 18 negative cases.MRI showed the highest positive detection rates for joint space narrowing,osteophyte formation at the joint margins,and free bodies in the joint cavity,each with a rate of 17.31%.The sensitivity,specificity,accuracy,positive predictive value,and negative predictive value of MRI were 92.31%,88.89%,91.43%,96.00%,and 80.00%,respectively.Conclusion MRI can effectively determine the types of lesions in knee degenerative osteoarthropathy and strengthen clinical diagnostic efficacy.
