MRI Shoulder: A Simple Guide to Your Scan

A Quick Note

Whether it's to reach for that high shelf or simply enjoying a good night's sleep, shoulder pain, clicking and lack of strength can make life very difficult. Your doctor may order an MRI (Magnetic Resonance Imaging) of the Shoulder if he or she wants to examine the inside of your shoulder, which includes your muscles, tendons and ligaments. It is used for in-depth analysis of the “soft tissues” that cannot be seen in X-rays.

What is an MRI Shoulder?

An MRI is an imaging test that creates strong magnetic fields and radio waves (no radiation) to generate high-resolution images and details of your shoulder joint.An MRI is the best imaging modality to evaluate the rotator cuff, tendons, ligaments and cartilage, while x-rays are useful for evaluating bones. It provides your doctor with some sort of "map" of your shoulder's internal functioning.

What is the point of the doctor ordering this scan?

In the event of a doctor suspecting:

· Rotator Cuff Tears: One of the most common reasons for shoulder pain, especially if you’ve had an injury.

· Labral Tears: Usually associated with shoulder instability and/or the "clicking" sensation.

· Tendinitis or Bursitis: Chronic inflammation that hasn't responded to physical therapy or rest.

· Frozen Shoulder: To check for thickening of the shoulder capsule.

· Persistent Pain/Weakness: If you have symptoms that can't be clearly identified by your doctor, based on physical examination.

How is the scan done?

· Preparation: There is no fasting required. However, all the metal objects (watches, jewelry, belts, etc.) will need to be removed as the MRI machine has a very powerful magnetic field. Some metal objects (such as a pacemaker or some surgical clips) will have to be reported before the scan as this may be dangerous for staff.

· The procedure: You will be on a table that will be placed in a long tube called an MRI scanner. It’s important to stay very still while the images are being taken.

· Noise: The machine is making a loud knocking or tapping noise when working – not a problem. Staff will supply ear plugs or headphones to aid with noise.

· Time: We typically can get all the pictures that you need in 30 minutes to 45 minutes.

Is MRI Shoulder Painful Test?

No, the test is non-painful. Many will just sit back and close their eyes and there will also be the ones who are just a little bit cramped in the tube.
