Are you looking for a quick and easy way to understand arthrograms? This medical imaging technique can diagnose joint and bone health issues, often involving the shoulder, elbow, wrist, and hip joints. However, many people may find the technical definition of this test confusing.
In our 2-minute guide to arthrograms, we’ll explain what this diagnostic imaging procedure involves in layman’s terms so that anyone interested in learning more can gain a better understanding of how it’s done. Let’s get started!
What is an Arthrogram?
An arthrogram is an imaging technique that involves both MRI and a series of X-rays after the injection of gadolinium, a contrast agent. The special injection enhances the visibility of the soft tissue structures of your joint, such as tendons, ligaments, muscles and cartilage.
With these images, your physician can diagnose conditions such as tears, inflammation, loose bodies, or fractures in the joint that otherwise may have gone undiagnosed.
The procedure is minimally invasive and usually causes no discomfort, making it a preferred option when your doctor needs to take a closer look to make an informed diagnosis.
Why Is an Arthrogram Done?
Arthrograms are typically ordered when there is a suspicion of injury or infection in a joint. The images produced by an arthrogram can help doctors determine if there is any damage to the tissues in and around the joint, as well as diagnose any inflammatory conditions such as arthritis.
In some cases, doctors may also order an arthrogram if they suspect that there may be loose parts within a joint, such as bone fragments or cartilage pieces.
How to Prepare for an Arthrogram
To ensure accurate results and optimal safety, it’s important to prepare in accordance with the instructions you will receive before the arthrogram. For example, you need to let your doctor know if you’re pregnant, have any metal implants, and whether you’re taking any medications, as it can all affect the examination.
You should also wear comfortable clothing and remove jewelry. If you suffer from anxiety, rest assured our compassionate staff will do everything they can to help you feel at ease. Many people find deep breathing exercises and relaxation techniques can reduce tension and worry. (Reading tip: Claustrophobic? Strategies to Deal with an MRI)
What Should I Expect During and After the Exam?
Depending on the type of arthrogram being performed, you may be positioned on a table or in an MRI machine with its cylinder-like opening.
Time to change
Once you have completed the preparation and changed into a hospital gown, the radiologist will inject the contrast dye. The contrast injection is normally done under a local anesthetic. After the dye has been injected, you will be asked to move the joint around to help distribute the dye and ensure that all areas of the joint are imaged. You will be monitored for a short time to ensure that you do not have any adverse reactions to the dye. (Reading tip: What is the Contrast in an MRI and Why Might I Need It?)
Waiting to finish
The length of the exam varies depending on the type of arthrogram being performed, the joint being examined, and the imaging technology used. Generally, an arthrogram can take anywhere from 15 minutes to one hour to complete.
Resuming activities
You may experience some discomfort or swelling in the joint for a few hours after the procedure, but this should go away on its own. You will be able to resume normal activities as soon as you feel comfortable. Once this process has been completed, your physician will review the images and schedule a time to discuss the findings.
Final Thoughts
An arthrogram is actually quite simple and straightforward—as long as you understand what it entails and what to expect during the procedure itself.
