Shoulder

A shoulder MRI offers a detailed view of bones, muscles, and soft tissues, making it essential for diagnosing injuries and uncovering the cause of shoulder pain to support effective treatment.

Shoulder MRI Scan: Your Complete Guide

MRI, which stands for magnetic resonance imaging, is a medical scanning technique that provides detailed insights into your internal body structures and anatomy. This allows your referring physician to identify any issues or assess the causes of symptoms.

Given that the shoulder joint includes bones, soft tissues such as cartilage and ligaments, blood vessels, lymph nodes, and muscles, an MRI exam is crucial for detecting shoulder injuries, determining the causes of shoulder pain, and obtaining an accurate diagnosis to guide your treatment plan.

When to Get a Shoulder MRI

Your doctor might recommend a shoulder MRI to investigate the following concerns:

• Shoulder Pain: This could be a symptom of various medical conditions, including:

• Rotator cuff disorders or tears.
• Rotator cuff tendinopathy (chronic tendon damage from overuse).
• Degenerative joint disorders, such as labral tears or fraying.
• Soft tissue damage.
• Bone fractures.
• Bursitis (inflammation of the fluid-filled sacs that lubricate the shoulder joint).

• Shoulder Instability: MRI can examine glenoid labrum damage, which is the soft fibrous tissue rim that stabilizes the humeral head (ball of the joint) and provides shock absorption. This damage can result from dislocation or subluxation (partial dislocation).
• Stiffness or Reduced Mobility: This could indicate a frozen shoulder.
• Post-Surgical Outcomes: Assess the outcomes of shoulder surgery and any complications.
• Pain, Swelling, Bleeding: These symptoms could indicate an infection.
• Lumps and Bumps: Evaluate these to determine if they could be tumors.

How long does a shoulder MRI take?
A shoulder MRI typically takes 15 to 45 minutes to complete. In some cases, the procedure may be as quick as 15 minutes.

The exact duration can vary depending on several factors:

• The number of images needed for a detailed analysis
• Whether contrast dye is used, which can add an extra 15-30 minutes
• If sedation is required for patients who have difficulty staying still

Procedures that require sedation may take 15 to 30 minutes longer.

What a Shoulder MRI Scan Detects

A shoulder MRI scan can help detect a variety of issues and conditions related to the shoulder joint, including:

1. Rotator Cuff Disorders:Rotator cuff tears
2. Labral Tears:Damage to the glenoid labrum, the fibrous rim of cartilage that helps stabilize the shoulder joint
3. Degenerative Joint Disorders:Osteoarthritis or other wear-and-tear changes in the shoulder joint
4. Soft Tissue Damage:Sprains or strains of the muscles, tendons, or ligaments around the shoulder
5. Bone Abnormalities:Fractures or other injuries to the bones of the shoulder (humerus, clavicle, scapula)
6. Bursitis:Inflammation of the fluid-filled bursa sacs that lubricate the shoulder joint
7. Shoulder Instability:Damage to the structures that help stabilize the shoulder joint, leading to dislocations or subluxations
8. Frozen Shoulder:Stiffness and limited range of motion in the shoulder joint
9. Surgical Complications:Issues or abnormalities following previous shoulder surgery
10. Tumors:Growths or masses in the shoulder area, including primary or metastatic cancers

The detailed images provided by an MRI allow radiologists to thoroughly evaluate the bones, cartilage, tendons, ligaments, and other soft tissues that make up the complex shoulder joint. This information is crucial for diagnosing the underlying cause of shoulder pain, instability, or other symptoms.

Do I need a contrast injection for my shoulder MRI?

Whether you need a contrast injection for your shoulder MRI depends on the specific reason for the scan and what your doctor is trying to evaluate. Here are a few key points:

• A shoulder MRI without contrast is the standard, baseline procedure to obtain detailed images of the bones, soft tissues, and joints in the shoulder area.
• Contrast dye, usually gadolinium, may be injected intravenously during the MRI if more detailed imaging is needed. This can help highlight certain structures and abnormalities that may not be as visible without contrast.
• Contrast is sometimes used when evaluating for suspected tumors, infections, or complications from prior shoulder surgery.
• Adding the contrast injection can extend the total scan time by an additional 15-30 minutes.
• Patients with certain medical conditions or allergies may not be able to receive the contrast dye.

So in summary, your doctor will determine if a contrast injection is necessary based on your specific symptoms, medical history, and what they are trying to diagnose or evaluate with the shoulder MRI. The decision to use contrast or not is made on a case-by-case basis. Be sure to discuss this with your doctor and the radiology staff before your scheduled MRI appointment.

How to Position Yourself for a Shoulder MRI

Here are the key steps for positioning yourself for a shoulder MRI:

1. Removal of Metal ObjectsYou will be asked to remove any metal jewelry, watches, or clothing with metal fasteners before the scan.
2. Lying on the TableYou will lie down on a motorized table that will slide into the MRI machine.
3. Entering the MRI MachineThe table will slowly slide you into the tunnel-shaped MRI machine.
4. Remaining StillIt is crucial that you remain very still during the MRI, as any movement can blur the images.
5. Contrast Injection (if needed)If contrast dye is required, an IV line will be placed in your arm before the scan.

Does your whole body go in for an upper arm or shoulder MRI?

A shoulder MRI is usually conducted with your entire body inside a traditional MRI scanner, although your feet might remain outside the machine.

For those with claustrophobia, an open MRI scanner might be recommended, as it allows for a clearer view of the surrounding room. However, open scanners have a lower magnetic field strength compared to traditional machines, making them unsuitable for certain types of MR imaging.

Schedule your MRI Scan

A shoulder MRI is a valuable, non-invasive diagnostic tool that provides detailed images of the shoulder's anatomy, aiding in the diagnosis and treatment of conditions such as rotator cuff tears, soft tissue damage, bone fractures, and bursitis. Offering both traditional and open MRI scanners, patients can select the most comfortable option for their needs.

Opting for a private MRI scan can help you avoid long wait times often associated with public healthcare systems like the NHS, leading to a quicker diagnosis and the first step toward rehabilitation and returning to your normal life.
