MRI of the shoulder can be useful for evaluating several clinical scenarios involving shoulder pain, trauma, impingement, instability, or limited range of motion. It allows visualization of bones, articulating surfaces, tendons, ligaments, labrum, bursae and other soft tissues. Common findings on MRI of the shoulder include tendinopathy, full and partial thickness rotator cuff tears, bursitis, and labral tears.

2. MRI of the shoulder may be useful to evaluate specific
clinical scenarios, including, but not limited to:
1. Prolonged, refractory, or unexplained shoulder pain
2. Acute shoulder trauma
3. Impingement syndrome: subacromial, subcoracoid, internal
4. Glenohumeral instability: chronic, recurrent, subacute, acute
dislocation, and subluxation
5. Shoulder symptoms in the overhead or throwing athelete
6. Mechanical shoulder symptoms: catching, locking, napping,
crepitus
7. Limited or painful range of motion
8. Swelling, enlargement, mass, or atrophy
9. Patients for whom diagnostic or therapeutic arthroscopy is
planned
10. Patients with recurrent, residual, or new symptoms following
shoulder surgery

5. Items to be evaluated(anatomy and pathology).

77. Bursitis is inflammation of a bursa. When injury
or inflammation of a bursa around the shoulder
joint occurs, shoulder bursitis is present.
