Analysis of the Diagnostic Value of CT and MRI in Knee Joint Motion Injury
Objective:To explore the diagnostic value of CT and magnetic resonance imaging(MRI)in knee joint motion injury.Methods:A total of 118 patients with suspected knee joint sports injury treated in the hospital from July 2020 to July 2022 were selected as the study objects.CT and MRI examinations were performed after admission,and the results of arthroscopy were taken as the'gold standard"to compare the single and combined diagnosis results,diagnostic efficacy of CT and MRI on knee joint sports injury.The detection rate of different types of knee joint injuries by CT and MRI was compared,and the consistency between the results of classification diagnosis of knee joint meniscus injury by CT and MRI alone and combined with arthroscopy was analyzed.Results:The results showed that 82 out of 118 patients with suspected knee joint motion injury were positive through arthroscopy,68 out of them were positive through CT examination,70 out of them were positive through MRI examination,and 81 out of them were positive through CT combined with MRI examination.The diagnostic sensitivity and accuracy of CT combined with MRI for knee joint motion injury were 95.12％and 94.07％,which were higher than those of single CT examination.Misdiagnosis was 4.88％,which was lower than CT examination and MRI examination(x2=9.260,7.040,0.270;P＜0.05).Compared with CT and MRI examination alone,the combined diagnosis has a higher detection rate,with statistically significant difference(x2=7.485,P＜0.05).The Kappa value of CT and MRI for meniscus injury classification was 0.674 and 0.716,respectively,and the Kappa value of joint examination was 0.869.Conclusion:CT combined with MRI examination can be used for early screening and diagnosis of knee joint sports injury,providing a basis for clinical evaluation of knee joint injury types,and targeted follow-up treatment to improve prognosis.
