多层螺旋CT与核磁共振成像在膝关节隐匿性骨折中的诊断价值对比

Comparison of Diagnostic Value of Multi-Slice Spiral CT and Magnetic Resonance Imaging in Occult Fracture of Knee Joint

目的:比较分析多层螺旋CT与核磁共振成像在膝关节隐匿性骨折诊断中的应用效果。方法:选取2019年1月-2020年8月本院收治的64例疑似膝关节隐匿性骨折患者为研究对象,经过手术和复查,确诊为膝关节隐匿性骨折34例,无膝关节隐匿性骨折30例。所有患者分别实施核磁共振成像与多层螺旋CT检查,分析诊断结果。结果:核磁共振成像的诊断特异度、灵敏度和准确率分别为90.00%、97.06%、93.75%,均高于多层螺旋CT的66.67%、76.47%、71.88%,组间差异有统计学意义(P<0.05)。结论:核磁共振成像检查在膝关节隐匿性骨折诊断中的应用效果比多层螺旋CT优,除清晰地反应病变状况外,有助于诊断准确率提高,值得今后临床诊断借鉴。

Objective:To compare and analyze the application effect of multi-slice spiral CT and magnetic resonance imaging in the diagnosis of occult fracture of knee joint.Methods:64 patients with suspected occult fracture of the knee joint admitted to our hospital from January 2019 to August 2020 were selected as the research objects.After operation and review,34 patients were diagnosed with occult fracture of the knee joint and 30 patients without.All patients underwent magnetic resonance imaging and multi-slice spiral CT examination,and the diagnostic results were analyzed.Results:The diagnostic specificity,sensitivity and accuracy of magnetic resonance imaging were 90.00%,97.06%and 93.75%,respectively,which were higher than 66.67%,76.47%and 71.88%of multi-slice spiral CT,the differences between the two groups were statistically significant(P<0.05).Conclusion:The application effect of magnetic resonance imaging in the diagnosis of occult fractures of the knee joint is better than that of multi-slice spiral CT.In addition to clearly reflecting the lesions,it is helpful to improve the diagnostic accuracy,which is worthy of reference for future clinical diagnosis.
