目的 分析低剂量双能量CT及MRI在前交叉韧带(ACL)损伤中的诊断价值.方法 选取2022年1月-2023年6月我院前交叉韧带损伤患者92例,分析其临床表现及影像学特征.结果 纳入92例患者临床确诊ACL损伤者53例,排除ACL损伤39例.低剂量双能量CT检查结果显示,灵敏度94.34％,特异度74.36％,阳性预测值83.33％,阴性预测值90.63％,准确率85.87％(79/92),kappa值为0.704;MRI检查结果显示,灵敏度96.23％,特异度87.17％,阳性预测值91.07％,阴性预测值94.44％,准确率92.39％,kappa值0.843.联合检测结果显示,灵敏度98.11％,特异度92.31％,阳性预测值94.55％,阴性预测值97.30％,准确率95.65％,kappa值0.910.结论 两者联合诊断灵敏度、特异度及准确度高于MRI诊断效果,高于低剂量双能量CT诊断效果.低剂量双能量CT与MRI诊断前交叉韧带损伤均有较高的灵敏度,可以互为备用方案.
Diagnostic Value of Low-dose Dual-energy CT and MRI in Anterior Cruciate Ligament Injury
Objective To analyze the diagnostic value of low-dose dual-energy CT and MRI in anterior cruciate ligament(ACL)injury.Methods A total of 92 patients with ACL injury in the hospital were enrolled between January 2022 and June 2023.The clinical manifestations and imaging characteristics were analyzed.Results Among the 92 patients,clinical diagnosis showed that there were 53 cases with ACL injury and 39 cases with ACL cysts.The sensitivity,sensitivity,positive predictive value,negative predictive value,accuracy and kappa values of low-dose dual-energy CT,MRI and combined detection were[94.34％,74.36％,83.33％,90.63％,85.87％(79/92),0.704],(96.23％,87.17％,91.07％,94.44％,92.39％,0.843)and(98.11％,92.31％,94.55％,97.30％,95.65％,0.910),respectively.Conclusion The diagnostic sensitivity,specificity and accuracy of combined detection are higher than that of MRI and low-dose dual-energy CT alone.Both low-dose dual-energy CT and MRI have high sensitivity in the diagnosis of ACL injury,and they can be mutually alternate.
