Intermediate consecutive axial scans nicely demonstrating the pectoralis major tendon both at its enthesis and at its musculotendinous junction. |

Comments
Although axial T1 weighted images are also adequate, intermediate (PD) axial scans through the proximal humerus, starting at the level of the glenohumeral joint and progressing to the upper one-third of the arm, depict the anatomy of the pectoralis major tendon optimally.
In many cases, the shoulder coil can be used, by simply sliding it down the arm from its usual position for shoulder exams. If not possible, a flexible coil, or the torso coil may be used.
Increase the FOV to 16-18 cm. to encompass the musculotendinous junction.
To the axial PD scans, add axial T2 fat-saturated images to evaluate signal changes / edema.
