摘要
目的探讨核磁共振成像(MRI)对膝关节半月板损伤的诊断效能。方法选择2018年3月-2020年10月我院骨科收治的疑似膝关节半月板损伤患者86例作为研究对象,均行MRI及膝关节镜检查,以关节镜检查结果为“金标准”,分析MRI诊断膝关节半月板损伤的检出率、灵敏度、特异度、准确度、Youden指数,采用Kappa值检验MRI与关节镜诊断半月板损伤的一致性。结果MRI对半月板损伤的检出率为83.72%、对半月板撕裂的检出率为70.93%,与关节镜检的87.21%、74.42%比较,差异无统计学意义(P>0.05);MRI诊断半月板损伤、撕裂的灵敏度、特异度、准确度、Youden指数分别为93.33%、81.82%、91.86%、75.15%和90.63%、86.36%、89.53%、76.99%;MRI对半月板损伤和撕裂的诊断效能与关节镜检查具有高度一致性,Kappa值为0.7530、0.7610。MRI及关节镜对半月板撕裂部位的检出率比较,差异无统计学意义(P>0.05)。结论MRI对膝关节半月板损伤检查的灵敏度、特异度及准确度均较高,与关节镜检查具有高度的一致性,可作为半月板损伤的首选检查方式。
Objective To explore the diagnostic efficacy of magnetic resonance imaging(MRI)for knee meniscus injuries.Methods From March 2018 to October 2020,86 patients with suspected knee meniscus injury admitted to the Department of Orthopedics of our hospital were selected as the research objects.All of them underwent MRI and knee arthroscopy.Using the results of arthroscopy as the"gold standard",analyze the detection rate,sensitivity,specificity,accuracy,and Youden index of MRI in the diagnosis of knee meniscus injury,and use Kappa to test the consistency of MRI and arthroscopy in the diagnosis of meniscus injury.Results The detection rate of meniscus injury by MRI was 83.72%,and the detection rate of meniscus tear was 70.93%.Compared with 87.21%and 74.42%of arthroscopy,the difference was not statistically significant(P>0.05);The sensitivity,specificity,accuracy and Youden index of MRI in diagnosing meniscus injury and tear are 93.33%,81.82%,91.86%,75.15%and 90.63%,86.36%,89.53%,76.99%,respectively;The diagnostic efficiency of MRI for meniscus injuries and tears was highly consistent with arthroscopy,with Kappa values of 0.7530 and 0.7610.There was no statistically significant difference in the detection rate of meniscus tears between MRI and arthroscopy(P>0.05).Conclusion MRI has high sensitivity,specificity and accuracy in the detection of meniscus injury of the knee joint.It has a high degree of consistency with arthroscopy and can be used as the first choice for meniscus injury.
