螺旋CT三维重建在膝关节退行性骨关节病中的诊断价值分析

Diagnostic Value of Spiral CT Three-Dimensional Reconstruction in Knee Degenerative Osteoarthrosis

目的探究螺旋CT三维重建技术在膝关节退行性骨关节病诊断中的价值。方法回顾性分析2018年5月至2019年5月期间到我院进行治疗58例膝关节退行性骨关节病患者相关影像学资料,患者接受X线与螺旋CT检查,其后采用关节镜予以确定与治疗。分析X线与螺旋CT三维重建技术诊断膝关节退行性骨关节病影像学表现,比较两种方式对关节病变情况、关节病变分型情况、关节病变分型诊断价值。结果 X线与螺旋CT均可观察到关节病变;螺旋CT三维重建诊断患者关节积液、滑膜改变、软骨改变、半月板变性、游离体等关节病变检出率显著高于X线(P<0.05);X线、螺旋CT三维重建技术与关节镜诊断关节病变分型差异没有统计学意义(P>0.05);以关节镜分级结果作为金标准,螺旋CT三维重建技术对关节病变分型诊断灵敏度、特异度以及准确度均优于X线诊断。结论膝关节退行性骨关节病应用螺旋CT三维重建技术诊断价值较高,可为患者提供有效影像学依据。

Objective To explore diagnostic value of spiral CT three-dimensional reconstruction in knee degenerative osteoarthrosis(OA).Methods A retrospective analysis was performed on related imaging data of 58 patients with knee degenerative OA who were treated in the hospital from May 2018 to May 2019.Patients underwent X-ray and spiral CT examination.Thenarthroscopy was conduct forconfirming and treatment.The imaging findings of X-ray and spiral CT three-dimensional reconstruction technique for diagnosis of knee degenerative OA were analyzed.The diagnostic value of the two method for joint lesions,joint lesion typing and joint lesion grading was compared.Results Joint lesions could be observed by both X-ray and spiral CT.The detection rates of spiral CT three-dimensional reconstruction for joint effusion,synovial changes,cartilage changes,meniscus degeneration and episome were significantly higher than those of of X-ray(P<0.05).There was no significant difference between X-ray,spiral CT threedimensional reconstruction technique and arthroscopy for diagnosis of joint lesions typing(P>0.05).Taking arthroscopic grading results as golden standard,diagnostic sensitivity,specificity,and accuracy of spiral CT three-dimensional reconstruction technique for joint lesion typing are superior to those of X-ray.Conclusion The diagnostic value of spiral CT three-dimensional reconstruction technique is relatively higher for knee degenerative OA,which can provide effective imaging basis for patients.
