Thirty-nine consecutive patients referred for shoulder arthrography underwent shoulder sonography to determine the ability of sonography to detect rotator cuff tears. Fifteen patients had arthrographically proven rotator cuff tears. Of these, 14 were detected by sonography, for a sensitivity of 93%. The three sonographic criteria indicative of rotator cuff tear were (1) discontinuity in the normal homogeneous echogenicity of the rotator cuff; (2) replacement of the normal homogeneous echogenicity by a central echogenic band; and (3) nonvisualization of the cuff. Twenty patients had normal sonographic examinations, 19 of which were normal by arthrography. Therefore, the predictive value of a negative sonogram was 95%. On the basis of these findings, sonography can provide a noninvasive means of screening patients with suspected rotator cuff tears.
39例因肩关节造影而转诊的患者接受了肩部超声检查，以确定超声检测肩袖撕裂的能力。15例患者经关节造影证实存在肩袖撕裂。其中，14例通过超声检测到，敏感性为93%。提示肩袖撕裂的三个超声标准为：（1）肩袖正常均匀回声的连续性中断；（2）正常均匀回声被中央回声带取代；（3）未显示出肩袖。20例患者超声检查正常，其中19例关节造影也正常。因此，超声检查阴性的预测价值为95%。基于这些发现，超声检查可为疑似肩袖撕裂的患者提供一种非侵入性的筛查方法。
