【摘要】 目的明确肩关节造影 MR 对肩关节前方盂唇病变的诊断价值,并比较中立位肩关节造影 MR 和外展外旋(abduction and external rotation,ABER)造影 MR 的价值。方法回顾性分析经证实的44例肩关节造影 MR 资料,以肩关节镜检查结果为金标准,对比中立位肩关节造影 MR 和ABER 造影 MR 对肩关节前方盂唇病变的诊断价值。结果中立位肩关节造影 MR 对前方盂唇的诊断敏感度为79.3%(23/29),特异度为100%(15/15),准确度为86.4%(38/44);ABER 造影 MR 的敏感度为93.1%(27/29),特异度为100%(15/15),准确度为95.5%(42/44)。ABER 造影 MR 显著提高了前方盂唇病变的诊断敏感度(P=0.037)。结论 ABER 造影 MR 可以提高肩关节前方盂唇病变的诊断敏感度。更多还原

【Abstract】 Objective To determine the diagnostic value of shoulder MR arthrography in revealing the injuries of anterior glenoid labrum,and to compare MR arthrography with arm in neutral position with MR arthrography with arm in abduction and external rotation(ABER)position.Methods MR arthrography of the shoulder,including additional oblique axial sequences with the patient in the ABER position,was performed in 44 patients.The injuries of anterior glenoid labrum of these patients were retrospectively evaluated.The result was compared with that of arthroscopy.Results For displaying the abnormalities of anterior glenoid labrum,the sensitivity,specificity,and accuracy of axial MR images with arm in neutral position were 79.3%(23/29),100%(15/15),and 86.4%(38/44),respectively.While the results of ABER position oblique axial images were 93.1%(27/29),100%(15/15),and 95.5%(42/44), respectively.The difference of sensitivity between axial and ABER-position scans was statistically significant (P<0.05).Conclusion MR arthrography with shoulder in the ABER position is more sensitive than conventional axial scanning in diagnosing the injuries of anterior glenoid labrum.更多还原
