Magnetic Resonance Imaging (MRI) is a safe and painless diagnostic test that uses radio waves and magnetic fields to create detailed images of your body’s internal structures. It’s a noninvasive way for doctors to diagnose a variety of health conditions.
When it comes to shoulder problems, an MRI can help diagnose soft tissue damage, joint issues, and other conditions affecting the shoulder.
So, how long does an MRI take for a shoulder? This article will give you a comprehensive overview of what to expect and the factors that can affect the duration of your scan.
How long does a shoulder MRI typically take?
The MRI scan itself usually takes between 15 and 45 minutes. Keep in mind that the total time you’ll spend at the imaging center will be longer than that.
The exact duration of your shoulder MRI will depend on a few things, including whether or not the radiologist uses contrast dye.
Contrast agents are sometimes used in MRIs to help the radiologist get a better view of certain tissues. This can be especially helpful in diagnosing problems within the shoulder joint.
If your MRI requires contrast dye, that will add about 30 minutes to the time required for the scan. All in all, with contrast dye, the procedure could take up to 90 minutes.
Factors Affecting Shoulder MRI Scan Time
The length of your shoulder MRI can be affected by a few different variables.
Specific anatomy and condition
The complexity of your shoulder joint, and the specific area being examined, can affect the scan time. If the technicians are focusing on a small area, it may take less time than if they’re imaging the entire joint.
Also, if your doctor suspects multiple or complex issues, the scan may take longer.
Need for additional scans or sequences
The use of specialized imaging to visualize specific tissues or problems will add to the overall scan time. And if you move during the scan, the images may be blurred and need to be retaken, further lengthening the procedure.
Technology and equipment
Newer MRI machines with advanced software are often able to produce images more quickly. And some facilities use artificial intelligence (AI) to improve image quality and reduce the overall scan time.
Preparing for Your Shoulder MRI
To make sure your shoulder MRI goes smoothly, there are a few things you’ll need to do before the scan.
Pre-Scan Instructions
It’s important to follow the pre-MRI instructions to a T to make sure the scan is both safe and effective. Here are a few things you’ll need to do:
- Take off any jewelry, hearing aids, or other metal items you might be wearing.
- Let the imaging center know if you have any metal implants or devices in your body.
- Wear comfortable, loose clothes that don’t have any metal fasteners.
Communication with the Imaging Team
Be sure to talk with the imaging team about any concerns you might have. This includes:
- Claustrophobia. If you’re worried about being in an enclosed space, let the team know so they can discuss options for sedation with you.
- Your medical history and any medications you’re taking. Bring a list of your current medications and let the technologist know about any other relevant health information.
What to Expect During the Shoulder MRI
During your MRI, you’ll lie on a table that slides into a large, tube-shaped magnet. It’s very important that you remain still throughout the scan, as any movement can blur the images. The technician will likely give you specific instructions on how to position your arm and shoulder.
The MRI machine makes a lot of noise during the scan. You’ll likely hear loud thumping or knocking sounds. Most facilities provide earplugs or headphones to help reduce the noise.
Wrapping Up
A shoulder MRI usually takes between 15 and 90 minutes, but several factors can affect the total time, including whether contrast dye is used and how easily your anatomy can be visualized.
For the smoothest, most successful MRI experience, it’s important to be prepared for the exam and to communicate clearly with the medical team.
An MRI is a safe and valuable diagnostic tool, and with the proper preparation, it can provide your doctor with the information needed to develop the right treatment plan for you.
