磁共振成像技术诊断膝关节损伤的价值

Value of Magnetic Resonance Imaging Technology in the Diagnosis of Knee Joint Injury

目的探析膝关节损伤患者应用磁共振成像技术进行诊断的临床效果。方法选取2021年10月—2023年10月新疆生产建设兵团第四师医院收治的68例疑似膝关节损伤患者为研究对象,所有患者均接受CT、磁共振成像检查,以关节镜检查诊断结果作为金标准,对比两种检查方式对膝关节损伤的检出率及诊断效能(灵敏度、特异度、准确度)。结果磁共振成像检查的准确度为97.06%(66/68)高于CT检查的80.88%(55/68),差异有统计学意义(χ^(2)=4.889,P<0.05)。磁共振成像检查的灵敏度高于CT检查,差异有统计学意义(P<0.05)。但两种检查方式的特异度比较,差异无统计学意义(P>0.05)。结论在膝关节损伤诊断中,磁共振检查具有良好的准确度和灵敏度,临床价值显著。

Objective To explore the clinical effect of magnetic resonance imaging in the diagnosis of knee joint injury.Methods A total of 68 patients with suspected knee joint injury admitted to the Fourth Division Hospital of Xinjiang Production and Construction Corps from October 2021 to October 2023 were selected as the study objects.All patients were accepted CT imaging examination and magnetic resonance imaging examination.The diagnose results of arthroscopy were used as the gold standard to compare the detection rate and diagnostic efficacy(sensitivity,specificity,accuracy)of the two examination methods for knee joint injury.Results The accuracy of magnetic resonance imaging examination was 97.06%(66/68),which was higher 80.88%(55/68)than of CT examination,and the difference was statistically significant(χ^(2)=4.889,P<0.05).The sensitivity of magnetic resonance imaging examination were higher than that of CT examination,and the difference was statistically significant(P<0.05).However,there was no statistically significant difference in the specificity between the two methods(P>0.05).Conclusion Magnetic resonance imaging has good accuracy and sensitivity in the diagnosis of knee joint injury,and the clinical value is significant.
