膝关节半月板周缘性脱位应用磁共振成像诊断的临床价值研究

A study on the clinical value of applying magnetic resonance imaging for the diagnosis of meniscus peripheral dislocation of knee joint

目的分析磁共振成像(MRI)应用于膝关节半月板周缘性脱位诊断中的价值。方法70例膝关节半月板周缘性脱位患者,随机分为对照组和研究组,每组35例。对照组采用多层螺旋CT诊断,研究组采用MRI诊断。以手术病理学诊断结果作为金标准,比较经多层螺旋CT和MRI对膝关节半月板周缘性脱位的损伤程度及内外侧脱位的诊断准确率。结果研究组损伤程度诊断准确率为94.29%,高于对照组的77.14%(P<0.05)。研究组内外侧脱位的诊断准确率为94.29%,高于对照组的77.14%(P<0.05)。结论MRI诊断膝关节半月板周缘性脱位临床价值高,适合推广和应用。

Objective To analyze the value of applying magnetic resonance imaging(MRI)for the diagnosis of meniscus peripheral dislocation of knee joint.Methods 70 patients with meniscus peripheral dislocation of knee joint were randomly divided into a control group and a study group,with 35 cases in each group.The control group was diagnosed by multi-slice spiral CT,and the study group was diagnosed by MRI.The diagnostic results of surgical pathology were used as the gold standard to compare the degree of injury of meniscus peripheral dislocation of knee joint and the diagnostic accuracy of medial-lateral dislocation by multi-slice spiral CT and MRI.Results The diagnostic accuracy of the degree of injury in the study group was 94.29%,which was higher than 77.14%in the control group(P<0.05).The diagnostic accuracy of medial-lateral dislocation in the study group was 94.29%,which was higher than 77.14%in the control group(P<0.05).Conclusion MRI has high clinical value in the diagnosis of meniscus peripheral dislocation of knee joint and is suitable for popularization and application.
