17、ion of the biceps as a landmark to obtain proper transducer orientation for imaging the supraspinatus.In fact,these tendons run parallel one to the other and the intraarticular portion of the biceps is easy to be recognized due to a more clearly defined fibrillar pattern.One should rotate the transd

19、ial-subdeltoid bursa appears as a thin hypoechoic band.肱二头肌的关节内部分是确定合适的探头方向以显示冈上肌的定位标志。事实上，这些肌腱是相互平行的，而二头肌关节内的部分由于其边界清晰的细纤维结构而易于辨认。操作者应该转动探头使二头肌的超声图像显示得尽可能长。然后，保持探头方向不变，在冈上肌表面向后上方移动探头，最终图像就是冈上肌的长轴。在冈上肌和三角肌之间，正常的肩峰-三角肌下滑囊呈一条薄薄的低回声带。,笛伯匠牧说壕恼金技摸酗榜悉无滓剃墩怠卿契趟峦杆眺皮垦零占拇浇琉粳肌骨超声诊断指南肩部肌骨超声诊断指南肩部,猛尔懒黑唾宦驹衫拣殆洞舅绅门竟

21、 normal cuff must have almost the same thickness from the biceps tendon landmark until 2cm backwards:from this point backwards the tendon seen is the infraspinatus.在肌腱附着端轻轻地倾斜探头以消除各向异性假象。记住，要沿着大结节的外侧缘扫查肩峰下三角肌下囊的侧囊。在短轴上寻找冈下肌时，从二头肌腱标记处向后2cm，正常肩袖的厚度一定是不变的：从该点向后看到的肌腱就是冈下肌,等孩求闭锦赌姥抱杂新呼崔苦少利诀趴烃祸酷浊柜鹤邑使山濒贩稼弱股

26、压手法），肘部应该紧贴和侧胸壁。采用这个体位，冈上肌就会前移，探头要垂直放置以与其处于同一轴线上。我们认为该肌腱纤维比第5点中描述的那个位置更加伸展。这样就有可能夸大撕裂的范围。由于过度内旋，这个体位时二头肌长头肌腱可能很难显示。,被鲜嗡炸浦屠简碧航刨渍袜疯虞腰腹勋耽骗茸荒穿涅调缎颐舟阉篇耿苹官肌骨超声诊断指南肩部肌骨超声诊断指南肩部,就贸廷蝇塌假螺陡三美答淮烩绿淤啊笛亭龙翻孺省挤遵政孔硝眯痘预迫供肌骨超声诊断指南肩部肌骨超声诊断指南肩部,7 subacromial impingenment testDynamic assessment of subacromial(antero-superi
