Sonography was performed in 41 patients with symptoms referable to the rotator cuff. Sonography was performed immediately after MR imaging, so that the information obtained by MR imaging could be applied to sonographic diagnosis. Twenty patients were diagnosed from T2-weighted images as having complete tears of the rotator cuff. Sonography showed full-thickness anechoic areas in 12 of the 20 patients, heterogeneous hyperechoic areas in seven, and no abnormal findings in the other one. Thirteen patients were diagnosed as having incomplete tears with MR imaging. Sonography showed heterogeneous hyperechoic areas in 12, but no abnormal findings in one of the 13. Hyperechoic areas in the rotator cuff were shown in four of eight patients who had been diagnosed from T2-weighted images as not having tears. We consider full-thickness anechoic areas to be specific findings of complete tears, although some patients with rotator cuff tears did not show this finding.
对41例有肩袖相关症状的患者进行了超声检查。超声检查在磁共振成像（MR成像）后立即进行，以便将MR成像获得的信息应用于超声诊断。20例患者经T2加权图像诊断为肩袖完全撕裂。超声检查显示，20例患者中有12例出现全层无回声区，7例出现不均匀高回声区，另1例未发现异常。13例患者经MR成像诊断为不完全撕裂。超声检查显示，13例中有12例出现不均匀高回声区，但有1例未发现异常。8例经T2加权图像诊断为无撕裂的患者中，有4例肩袖出现高回声区。我们认为全层无回声区是完全撕裂的特异性表现，尽管一些肩袖撕裂患者未出现此表现。
