上肩盂唇前后(SLAP)撕裂:基于3TMR肩关节成像的诊断,三维TSE序列与传统2D序列的比较

引用

国际医学放射学杂志 2013年第2期 200-200页

作者： J.Y. Jung W.H. jee M.Y. Park S.Y. Lee Y.S. kim 郭凌飞 Department of Radiology Seoul St. Mary’s Hospital College of Medicine The Catholic University of Korea 505 Banpo-dong Seocho-gu Seoul 137-701 South Korea

目的本研究旨在探讨应用3D-TSE-SPACE(samp-lingperfectionwithapplication-optimisedcontrastsusingdiffer-entflipangleevolution)肩关节MR成像对上肩盂唇前后(SLAP)病变的诊断并与3.0TMR2DTSE序列对该病的诊断进行比较。材料与方法肩关节MR成像包括2DTSE序列与3DTSE-SPACE序列,由2名观察者回顾性分析87例接受肩关节成像病人的SLAP病变的存在及病变类型。使用McNemar’s检验对敏感性及特异性进行比较,Cohen’skappa法对观察者内部的一致性进行检验并分析受试者操作特征曲线。结果 2DTSE序列的平均敏感度、特异度、精确度分别为90%、85%、86%,3DTSE-SPACE序列为81%、86%、85%,两者之间差异没有统计学意义。2DTSE序列成像与3DTSE-SPACE的观察者内部的一致性均稳定(κ=0.76、0.68),2DTSE序列成像与3DTSE-SPACE在ROC曲线下的面积分别为0.92和0.90,差异没有统计学意义。结论 3DTSE-SPACE序列的MR肩关节成像对SLAP病变诊断具有较稳定的一致性并且具有较高的准确性。要点①MR关节成像被认为是肩关节成像的决定性方法。②多种不同的MR序列可以对SLAP病变进行检查。③与2DTSE序列相比,SLAP病变3DTSE-SPACE成像具有大致相同的精确性。④但是在3DTSE-SPACE成像中会出现更多的假阴性结果。⑤在使用3DTSE-SPACE成像代替2DTSE序列扫描之前,在技术上还需要进一步的提高。
