Imaging Review of Subscapularis Tendon and Rotator Interval Pathology

Figure 4

Normal MR arthrogram: axial T1-weighed FS (a) and sagittal T1-weighted (b) MRI show an intact subscapularis tendon (long arrow in a and b), long head of the biceps tendon (short arrow in a and b), supraspinatus muscle (SSM), infraspinatus muscle (ISM), and teres minor (TM). Note. In addition, there are some extra-articular contrast material deposition anterior to the subscapularis tendon (arrowhead in a) and minor contrast deposition within the musculotendinous junction of the subscapularis (arrowhead in b).
