Shoulder pain is a common complaint for the active Colorado population. Symptoms often occur from trauma or damage from overuse. The shoulder is a very complex joint, and understanding the cause of pain is critical for proper treatment. While an X-ray is useful for seeing broken bones, a shoulder MRI provides a detailed look at the joint and soft tissues between the bones.
MRI stands for magnetic resonance imaging, an imaging technology that uses magnets and radio waves to produce detailed 3D imaging of the shoulder and joint. These signals are then converted to images for the radiologists to interpret. MRI is commonly performed to distinguish normal tissues from injured or pathologic tissues.
An MRI can be used:
Your doctor may recommend a shoulder MRI to evaluate subtle injuries to the labrum, which provides cushioning between the bones of the shoulder, the ligaments, or fibrous bands that hold the joints together, or the tendons, which connect the bones to muscles — providing a detailed map to use for future therapy or surgery. Shoulder MRIs are helpful in examining:
Rotator cuff injuries
Ligament injuries
Tendon injuries
Labral tears or injuries
Tissue swelling or tears
Injury after trauma
The shoulder is a complex joint referred to as a "ball and socket," which allows for great rotation. The shoulder's strength comes from the muscles that make up the shoulder and allow movement in all directions. Approximately twenty muscles comprise and support the shoulder joint. Some of these muscles make up the cuff around the joint known as the rotator cuff.
MRI is useful to diagnose whether an acute (sudden) or long-standing (chronic) labrum tear or a rotator cuff tear may be the cause of pain or loss of function. An MRI can also provide details on the severity of the tear, such as whether it is partial or complete. Sometimes an MRI only shows swelling of these soft tissue structures and not a tear. MRI images are helpful for a physical therapist or orthopedic surgeon because they provide a detailed map to use for future physical therapy or surgery.
Arthritis is usually best evaluated with X-rays. If the degree of shoulder pain or dysfunction does not agree with the x-ray findings, an MRI may be useful.
The MRI imaging may take 25 to 35 minutes, depending on whether special imaging sequences are needed. The complexity of shoulder or joint imaging may affect the time required to perform the imaging scan.
