| 摘 要： | 目的评价三维扰相脂肪抑制梯度回波序列(3D-WATSc)在膝关节软骨缺损性病变中的诊断价值。方法 41例患者50侧膝关节镜检查病例,将每侧膝关节软骨面分为5个区域,MRI检查采用3D-WATSc,按Recht标准分级诊断250个关节软骨面,并与膝关节镜分级诊断结果对照。3D-WATSc诊断价值的真实性指标为敏感度、特异度、准确度,一致性指标用Kappa值。结果 3D-WATSc诊断软骨病损的敏感度为96.4%,特异度为87.3%,准确度为92.4%,Kappa值为0.844。结论 3D-WATSc与关节镜对膝关节软骨病损的诊断结果之间一致性极佳,是目前诊断膝关节软骨病损的最佳扫描序列。

| Abstract: | Objective To evaluate diagnostic value of 3D WATSc sequence in articular cartilage injury of knee.Methods 41 patients with 50 knee joints were collected and 3D WATSC was used.Each side of cartilage was divided into five parts.250 articular cartilage according to Recha criteria were selected and compared with arthroscopic examination respectively.Sensitivity,specificity and accuracy of 3D-WATSc MRI sequences were evaluated.The criteria of correlation used the value of Kappa.Results The sensitivity,specificity,accuracy and Kappa value of the 3D WATSC was 96.4%,87.3%,92.4% and 0.844 respectively.Conclusion The 3D-WATSc MRI sequence is well consistent with the result of arthroscopy,which is the adequate sequence in detecting articular cartilage injury of the knee. |
