磁共振成像与CT检查诊断膝关节损伤的临床效果

目的:比较分析磁共振成像与CT检查诊断膝关节损伤的临床效果。方法:2018年1月~2019年12月选取40例膝关节损伤患者,均采取磁共振成像与CT检查。以患者关节镜手术的结果作为参考依据,比较患者磁共振成像与CT检查总检出率、灵敏度、特异度,Kappa检验磁共振成像、CT与关节镜手术的一致性,比较磁共振成像与CT对十字韧带损伤、骨骼损伤、关节处积液以及半月板损伤等膝关节损伤的临床实际检出率。结果:磁共振成像总检出率(97.50%)、诊断灵敏度(97.44%)、特异度(100.00%)均高于CT(75.00%、76.92%、0),P<0.05,磁共振成像与关节镜的一致性较好(Kappa值=0.724),CT与关节镜的一致性一般(Kappa值=0.542),组间数据差异在统计学上有意义(P<0.05);磁共振成像检查对于十字韧带损伤、骨骼损伤、关节处积液以及半月板损伤的检出率分别为100.00%(10/10)、100.00%(14/14)、90.00%(9/10)、100.00%(6/6),均明显高于CT检查的60.00%(6/10)、85.71%(12/14)、70.00%(7/10)、83.33%(5/6),组间数据差异在统计学上有意义(P<0.05)。结论:磁共振成像诊断膝关节损伤的临床效果显著优于CT检查,能有效检出十字韧带损伤、骨骼损伤、关节处积液以及半月板损伤状况。

Clinical Effect of Magnetic Resonance Imaging and CT Examination in Diagnosis of Knee Joint Injury

Objective:To compare and analyze the clinical effect of magnetic resonance imaging and CT examination in the diagnosis of knee injury.Methods:From January 2018 to December 2019,40 patients with knee joint injuries were selected,and all were examined by magnetic resonance imaging and CT.Using the results of arthroscopic surgery of the patient as a reference basis,compare the total detection rate,sensitivity,and specificity of the patient’s MRI and CT examination.Kappa examines the consistency of MRI,CT and arthroscopic surgery,and compares MRI and CT The actual clinical detection rate of knee joint injuries such as cruciate ligament injury,bone injury,joint effusion and meniscus injury.Results:The total detection rate of MRI(97.50%),diagnostic sensitivity(97.44%),and specificity(100.00%)are all higher than those of CT(75.00%,76.92%,0),P<0.05,the difference between MRI and arthroscopy The consistency is good(Kappa value=0.724),the consistency between CT and arthroscopy is general(Kappa value=0.542),the data difference between groups is statistically significant(P<0.05);MRI examination is for cruciate ligament injury The detection rates of,bone injury,joint effusion and meniscus injury were 100.00%(10/10),100.00%(14/14),90.00%(9/10),100.00%(6/6),respectively.All were significantly higher than the CT examination of 60.00%(6/10),85.71%(12/14),70.00%(7/10),83.33%(5/6),and the difference in data between groups was statistically significant(P<0.05).Conclusion:The clinical effect of magnetic resonance imaging in the diagnosis of knee injury is significantly better than CT examination.It can effectively detect cruciate ligament injury,bone injury,joint effusion and meniscus injury.
