The accuracy of ultrasonography and arthrography in the prediction of lesions of the rotator cuff was evaluated and compared with the operative findings in a retrospective study of forty-nine patients (forty-nine shoulders). In the detection of full-thickness (stage-III) tears of the rotator cuff, ultrasonography had an over-all sensitivity of 74 per cent, a specificity of 95 per cent, an accuracy of 84 per cent, a predictive value of a positive test of 95 per cent, and a predictive value of a negative test of 75 per cent. In contrast, arthrography demonstrated a sensitivity of 93 per cent, a specificity of 95 per cent, an accuracy of 94 per cent, a predictive value of a positive test of 96 per cent, and a predictive value of a negative test of 91 per cent. Ultrasonography could not reliably differentiate between partial (stage-II) and full-thickness (stage-III) tears. Lesions of the long head of the biceps brachii tendon were recorded by ultrasonography for twenty-two patients (45 per cent) and by arthrography for eleven patients (22 per cent). The ultrasonographic finding of fluid in the sheath of this tendon is not a reliable sign of a lesion in the tendon.
在一项对49例患者（49个肩部）的回顾性研究中，对超声检查和关节造影在预测肩袖损伤方面的准确性进行了评估，并与手术结果进行了比较。在检测肩袖全层（III期）撕裂时，超声检查的总体敏感性为74%，特异性为95%，准确性为84%，阳性试验预测值为95%，阴性试验预测值为75%。相比之下，关节造影显示敏感性为93%，特异性为95%，准确性为94%，阳性试验预测值为96%，阴性试验预测值为91%。超声检查无法可靠地区分部分（II期）和全层（III期）撕裂。超声检查记录到22例患者（45%）肱二头肌长头肌腱损伤，关节造影记录到11例患者（22%）。该肌腱腱鞘内有液体的超声检查结果并非肌腱损伤的可靠征象。
