摘　　要：目的:探讨与分析多层螺旋CT三维重建技术在老年膝关节退行性损伤诊断中的应用价值.方法:选择2019年9月—2023年2月莒南县中医医院收治的86例老年膝关节退行性损伤患者作为研究对象.所有患者都给予多层螺旋CT三维重建技术检查和关节镜检查,并以关节镜手术结果作为判断的金标准,记录影像学特征.结果:多层螺旋CT三维重建显示为关节积液81例,半月板变性76例,骨质改变71例,充气征67例,游离体73例,双边征71例,分别占比94.19%、88.37%、82.56%、77.91%、84.88%、82.56%.在86例患者中,多层螺旋CT三维重建判断为关节损伤1级56例,2级20例,3级6例,4级4例;关节镜判断为关节损伤1级52例,2级22例,3级8例,4级4例,两种方法对比无明显差异(P>0.05).多层螺旋CT三维重建技术在老年膝关节退行性损伤诊断中的准确性和敏感性均为95.35%;ROC曲线显示多层螺旋CT三维重建技术在老年膝关节退行性损伤诊断曲线下面积为0.834(95%CI:0.782~0.966).结论:多层螺旋CT三维重建技术在老年膝关节退行性损伤诊断中的应用能清晰显示病变特征,具有很高的诊断价值,可作为老年膝关节退行性损伤的重要检查方法.Objective:To explore and analyze the application value of multi-slice spiral CT 3D reconstruction in the diagnosis of degenerative knee joint injury in the elderly.Methods:86 elderly patients with degenerative knee joint injury treated in Junan County Hospital of Traditional Chinese Medicine from September 2019 to February 2023 were selected as the study objects.All patients were given multi-slice spiral CT 3D reconstruction and arthroscopy,and the results of arthroscopic surgery were used as the gold standard to record the imaging features.Results:Three-dimensional reconstruction of multi-slice spiral CT showed joint effusion in 81 cases,meniscal degeneration in 76 cases,bone change in 71 cases,air sign in 67 cases,free body in 73 cases,bilateral sign in 71 cases,accounting for 94.19%,88.37%,82.56%,77.91%,84.88%,82.56%,respectively.Among the 86 patients,multi-slice spiral CT 3D reconstruction was judged as joint injury grade 1 in 56 cases,grade 2 in 20 cases,grade 3 in 6 cases,and grade 4 in 4 cases.There were 52 cases of joint injury in grade 1,22 cases in grade 2,8 cases in grade 3,and 4 cases in grade 4 by arthroscopy.There was no significant difference between the two methods(P>0.05).The accuracy and sensitivity of multi-slice spiral CT in the diagnosis of degenerative knee injury in elderly patients were 95.35%.ROC curve showed that the area under the diagnosis curve of degenerative knee injury in elderly patients with multi-slice spiral CT was 0.834(95%CI:0.782~0.966).Conclusion:The application of multi-slice spiral CT 3D reconstruction in the diagnosis of elderly knee degenerative injury can clearly show the characteristics of the lesions,which has high diagnostic value,and can be used as an important examination method for elderly knee degenerative injury.
