MRI of the shoulder. Axial T1-weighted view. Image 11

1, Pectoralis major muscle. 2, Biceps tendon (long head). 3, Deltoid muscle (anterior). 4, Humeral head. 5, Glenoid. 6, Teres minor muscle. 7, Deltoid muscle. 8, Infraspinatus muscle. 9, Subscapularis muscle. 10, Coracobrachialis muscle. 11, Pectoralis minor muscle.

Axial view can give us information about the following:

1-Anterior and posterior labrum.

2-Head of the humerus with bicipital groove containing biceps muscle tendon long head.

3-Subscapularis muscle present between scapula and the chest wall with its tendon inserting into lesser tuberosity(best view for subscapularis).

4-Infraspinatus muscle is seen lateral to the humerus with its tendon inserted into greater tuberosity.

5- Supra spinatus could not be seen usually by axial view.

6-Laterally to infra spinatus, there is deltoid muscle.
