The effect of humeral rotation on the appearance of the rotator cuff tendon in oblique coronal magnetic resonance images was evaluated in 70 such images. Internal rotation produced overlap of the supraspinatus and infraspinatus tendons with soft-tissue interposition or apparent discontinuity of the tendon in 22 cases, including 14 of 15 shoulders positioned in the first 30 degrees between extreme internal and external rotation. Imaging in internal rotation makes assessment of the tendon difficult and should be avoided.
在70幅此类斜冠状面磁共振图像中评估了肱骨旋转对肩袖肌腱在图像中外观的影响。内旋导致22例冈上肌和冈下肌腱重叠，伴有软组织插入或肌腱明显中断，其中15个肩部中有14个处于极度内旋和外旋之间的前30度位置。内旋成像会使肌腱评估变得困难，应予以避免。
