Accuracy of MRI, MR Arthrography , and Ultrasound in the Diagnosis of Rotator Cuff Tears: A Meta-Analysis MRI 、 MR 关节造影、超声诊断肩袖撕裂的准确性: Meta 分析? OBJECTIVE. ? The purpose of this study was pare the diagnostic accuracy of MRI,MR arthrography , and ultrasound for the diagnosis of rotator cuff tears through a meta- analysis of the studies in the literature. 目的:通过学****文献进行一个 meta 分析,来比较 MRI 、 MR 关节造影和超声在诊断肩袖撕裂的准确性。? MATERIALS AND METHODS. ? Articles reporting the sensitivities and specificities of MRI, MR arthrography , or ultrasound for the diagnosis of rotator cuff tears were identified. Surgical(open and arthroscopic) reference standard was an inclusion criterion. Summary statistics were generated using pooled data. Scatterplots of the data sets were plotted on a graph of sensitivity versus (1 – specificity). Receiver operating characteristic (ROC) curves were generated. 材料与方法:文献报道, MRI 、 MR 关节造影和超声在诊断肩袖撕裂的敏感性和特异性是确定的。外科手术(切开和关节镜)的证明标准是一种收入标准,通过对汇总数据的总结形成统计数字、数据设置的散点绘图,在一张敏感性对( 1-特异性)的图上进行标绘,就形成 Receiver operating characteristic ( ROC )曲线。? RESULTS. ? Sixty-five articles met the inclusion criteria for this meta-analysis. In diagnosing a full-thickness tear or a partial-thickness rotator cuff tear , MR arthrography is more sensitive and specific than either MRI or ultrasound (p < ). There are no significant differences in either sensitivity or specificity between MRI and ultrasound in the diagnosis of partial- or full-thickness rotator cuff tears (p > ). 结果: 65篇文章符合这个 meta 分析的收入标准。在诊断一个完全或部分的肩袖撕裂时, MR 关节造影比 MRI 或超声更敏感和专业( p< )。在诊断完全或部分肩袖撕裂时, MRI 和超声在敏感性和特异性方面没有显著区别( p> )。? Summary ROC curves for MR arthrography,MRI , and ultrasound for all tears show the area under the ROC curve is greatest for MR arthrography (), followed by ultrasound () and then MRI (); however,parisons of these curves show no significant differences between MRI and ultrasound (p > ).
