Shoulder MRI Scan: Purposes, Procedure, and Risks

From athletes to normal individuals, an injured or painful shoulder can be a major setback. Whether you have a big sports event coming up, or you just need to be able to handle your groceries without flinching, you would need a perfectly mobile shoulder. So, if you’re experiencing persistent discomfort, it may be time to get an MRI of the shoulder.

MRI is one of the most efficacious and futuristic scanning procedures in modern medical setups. The American Academy of Neurology confirms that it is even better than CT scans when diagnosing strokes. It is a non-surgical method of examining the body with clarity and precision. It is suitable to diagnose complications in any part of the human body. However, a shoulder MRI scan specifically highlights the internal structure of the shoulder region.

This blog details the purpose, procedure, and risks involved with a shoulder MRI.

Introducing Shoulder MRI Scans: How do they work?

An MRI machine uses powerful magnetic and radio waves to produce high-definition and vivid images of the internal body. Typically, an MRI scan that specially targets the shoulder helps the doctors view the soft tissues, ligaments, tendons, bones, blood vessels, and even nerves in the area. Later, medical experts view these fine images on the computer screen to identify any flaws or deviations.

An MRI scan proceeds as the magnetic field momentarily aligns your body’s hydrogen atoms. Then, the radio waves cause these aligned particles to emit energy signals, which the machine records as images.

When is an MRI Scan Suggested?

Mostly, doctors recommend MRI scans to understand unidentified symptoms across the patient’s shoulder. For instance, unexplained stress, pain, or a recent injury. Consequently, it helps healthcare experts trace the root cause of the symptoms, identify abnormalities, and plan a treatment accordingly.

Luckily, MRI is a safer alternative when compared to X-rays and CT scans. This is because it does not use any harmful radiation. Hence, it is a preferred choice for sensitive patients, infants, and pregnant women. These scans are exceptionally helpful in early diagnosis and careful treatment of health issues. Therefore, they equally benefit healthcare professionals and patients.

What can a shoulder MRI scan diagnose?

Since MRI scans are very meticulous, they can pinpoint the most minor changes in the body. Therefore, shoulder scans are beneficial in diagnosing the following issues:

• Bone fractures
• Ligament or cuff tears
• Shoulder joint dislocation
• Injuries due to pressure or fall
• Swelling or inflammation
• Unidentified pain or muscular tension
• Infections
• Cartilage tears
• Tumors
• Serious joint disorders like arthritis or osteoporosis
• Problems with movement
• Tracking recovery progress post-surgery or physiotherapy

How to prepare for a shoulder MRI scan?

Usually, you need no special preparation for an MRI scan because of its quick and simple nature. Despite that, there are some guidelines you need to follow prior to the scan such as comfortable, loose-fit clothing and no metal accessories. Also, if you are claustrophobic, you can inform the radiologist beforehand. They may provide you with antistress medicines or sedatives to avoid any inconvenience during the procedure.

Moreover, you are sometimes advised to observe fasting 6 to 8 hours before a scheduled shoulder MRI. Importantly, if you have had any metallic implants like stents or pacemakers, let the professionals know earlier. Metal components are not permitted in the room containing the MRI scanner due to the use of powerful magnets.

Risks of a shoulder MRI scan

Generally, MRIs are safer than other imaging tests. However, some risks are still associated with the procedure. For example:

Claustrophobia

The most common concern in MRI scans is the confined, tunnel-like space in which the patient lies. Majorly, this is a big drawback for people who feel anxious and claustrophobic in closed spaces. Gladly, today there are options for ‘open MRI scanners’ for such patients. If this is a concern for you, talk to your healthcare provider beforehand.

Metal Implants

Since MRIs use strong magnets, people with certain metal implants (such as pacemakers, joint replacements, or metal plates) may not be eligible for the scan. Always inform the technician about any metal in your body. Special procedures are used for patients with implants.

Contrast Dye Reactions

Though rare, some people may have an allergic reaction to the contrast dye used during the MRI. Symptoms can include itching, rash, or dizziness. If you have a known allergy to gadolinium, let your doctor know. Furthermore, mothers who undergo MRI scans cannot breastfeed their children for up to 48 hours.

How is a shoulder MRI performed?

Normally, the process of MRI of the shoulder is uncomplicated and fast-paced. Here is a step-by-step guideline of the entire process:

• Preparation: Firstly, you may need to change into a gown and remove additional accessories.
• Check-In: Secondly, you’ll be asked about any metal implants or allergies, as well as your health history.
• Positioning: Then, the technician will help you lie down on a padded table and position your shoulder for clear imaging.
• Contrast Dye (if needed): Sometimes, a dye is injected into your shoulder to enhance the images. It may sting briefly.
• The Scan: Later, you’ll be moved into the MRI machine, which looks like a large tube. You’ll need to stay still while the machine takes pictures. Commonly, the process lasts for 20-60 minutes.
• Afterward: You can go back to normal activities immediately. If you had contrast dye, drink some water to flush it out. That’s it! The MRI is quick, safe, and non-invasive.

Closing remarks – Safe and Effective Shoulder Imaging

A shoulder MRI can be a game-changer in diagnosing and treating shoulder injuries, helping doctors pinpoint issues like rotator cuff tears, arthritis, or labral injuries. While the procedure is generally safe and non-invasive, it’s important to be aware of potential risks, such as claustrophobia or allergic reactions to contrast dyes. Regardless, understanding the purpose and process of a shoulder MRI can help alleviate any fears and ensure you’re well-prepared.

If you’re experiencing persistent shoulder pain, don’t ignore it—talk to your doctor and go for professional medical imaging services. Early diagnosis and the right treatment plan can help you get back to lifting groceries—and your favorite hobbies—in no time.
