CT与MRI在膝关节软骨损伤分级诊断中的效能分析

Efficacy analysis of CT and MRI in grading of knee cartilage injury

目的:探究CT与MRI在膝关节软骨损伤分级诊断中的效能。方法:回顾性选取我院2021年1月-2023年1月收治的80例膝关节软骨损伤患者为研究对象,对所有患者行CT、MRI和关节镜检查,通过关节镜检查的结果,评估二者的分级诊断效能,并比较CT与MRI在膝关节软骨损伤分级诊断中的诊断价值。结果:患者经CT检查诊断的分级结果为Ⅰ级28例,Ⅰ级34例,Ⅲ级及以上18例;经MRI检查诊断的分级结果为Ⅰ级31例,Ⅱ级29例,Ⅲ级及以上20例。与关节镜检查的结果对比,CT的分级诊断准确率为81.25%(65/80),MRI的分级诊断准确率为95.00%(76/80)。MRI检查诊断膝关节软骨损伤患者的I级诊断准确率、总准确率要高于CT检查,差异有统计学意义(P<0.05)。结论:CT与MRI均可对膝关节软骨损伤进行分级诊断,但MRI对膝关节软骨损伤分级的诊断准确率高于CT,具有更高的诊断效能。

Objective:To explore the efficacy of CT and MRI in the grading of knee cartilage injury.Methods:A total of 80 patients with knee joint cartilage injury admitted to our hospital from January 2021 to January 2023 were retrospectively selected as the study objects.CT,MRI and arthroscopy were performed on all patients,and the grading diagnostic efficacy of both were evaluated according to the results of arthroscopy.The diagnostic value of CT and MRI in the classification of knee cartilage injury was compared.Results:The results of CT diagnosis were 28 cases of grade Ⅰ,34 cases of grade Ⅱ and 18 cases of grade Ⅲ and above.The grading results of MRI diagnosis were 31 cases of grade Ⅰ,29 cases of grade I,and 20 cases of grade Ⅲ and above.Compared with the results of arthroscopy,the accuracy of CT grading was 81.25%(65/80)and that of MRI grading was 95.00%(76/80).The accuracy and total accuracy of grade Ⅰ diagnosis in patients with knee cartilage injury were compared between CT and MRI,and the difference was statistically significant(P<0.05).Conclusion:Both CT and MRI can be used to grade knee cartilage injury,but MRI has higher diagnostic accuracy than CT and has higher diagnostic efficiency.
