When is an MRI of the shoulder used?

An MRI scan of the shoulder is recommended when other methods such as X-ray or ultrasound have not given a clear result, or when more detailed information about the structures inside the shoulder joint is needed. Common reasons for an MRI include ongoing shoulder pain, restricted movement, suspected tendon tears (for example in the rotator cuff), injuries following an accident, or unexplained swelling. It can also help find the cause of long-term problems that have not improved with treatment.

For sports injuries, after a fall, or when a tear in the labrum is suspected, which is a cartilage structure around the edge of the shoulder socket, an MRI scan provides important information. Inflammation, bursitis, and changes to the shoulder muscles can also be clearly identified.

What can an MRI of the shoulder show?

Because of its high image quality, even small changes can be seen on an MRI. These include tendon tears, inflammation, tears in the labrum, cartilage damage, and changes in the area of the shoulder girdle. Bursitis and fluid build-up also become visible. Bone fractures that cannot be seen on standard X-rays can be shown as well.

Sometimes a contrast agent is used during the MRI scan. It is injected into a vein and helps certain structures stand out more clearly. Whether this is necessary is decided by the doctor depending on what they are looking for.

How does the scan work?

Before the scan begins, all metal objects must be removed, as MRI uses strong magnetic fields. During the procedure, the affected shoulder rests in a special holder to keep it as still as possible. The machine makes loud knocking and humming sounds. Earplugs or headphones help to reduce the noise. The MRI does not cause pain. However, it may feel slightly uncomfortable for people who experience claustrophobia, as the scan takes place inside a narrow tube. In such cases, there are ways to make the experience more comfortable, or an open MRI scanner can be chosen.

What should you be aware of after an MRI of the shoulder?

After the scan, daily activities can usually be continued as normal. If a contrast agent was used, it is important to drink plenty of fluids to help the body remove it more quickly. The images are reviewed by a radiologist. The report is then sent to the treating doctor, who will discuss the results with you.

What does the MRI result mean?

The MRI images give very precise clues about the possible causes of symptoms. Common findings include tendon tears, inflammation, tears in the labrum, or signs of arthritis in the shoulder joint. The exact meaning always depends on the individual images and the symptoms present. Not every unusual finding automatically requires treatment. Sometimes age-related changes are visible that do not cause any symptoms at all.

Whether and how treatment is needed is decided after a conversation with a specialist. The treatment always depends on the diagnosis and the symptoms. This may include physiotherapy, medication, or in rare cases surgery.

How does it compare to other examinations?

Compared to X-ray or ultrasound, MRI provides particularly good images of soft tissues such as tendons, muscles, and cartilage. While X-ray is mainly used to identify bone fractures, MRI can also reveal small tears, inflammation, or fluid build-up. Ultrasound is useful for an initial assessment but is not as detailed as MRI.

Connections with other structures

The shoulder joint is a complex arrangement of bones, muscles, tendons, capsules, and ligaments. An MRI scan can show all of these structures in detail.

MRI of the shoulder joint is an important tool for finding the cause of shoulder problems and making it possible to treat them effectively.
