Double contrast shoulder arthrograms revealed rotator cuff abnormalities in 14 of 31 cases. Although both the single and double contrast methods provide a means of diagnosing complete tears of the cuff, or partial tears of its inferior surface, the double contrast study provides additional information regarding the width of the tear, the presence of degenerative changes in the cuff, and the condition of the articular cartilages.
双重对比肩关节造影显示，31例中有14例存在肩袖异常。虽然单对比和双重对比方法都提供了诊断肩袖完全撕裂或其下表面部分撕裂的手段，但双重对比研究提供了关于撕裂宽度、肩袖退变改变的存在以及关节软骨状况的额外信息。
