MRI Arthrogram – July 2019
by Michael Wang, MD
MRI Arthrogram is a special type of MRI that involves the use of contrast or dye to better visualize the small structures of the joints.
Let’s first talk about what contrast is.
Definition: “The state of being strikingly different from something else in juxtaposition or close association.”
In the example below, the top rectangle has high contrast.
The bottom rectangle has poor contrast.
In the MRI images of the wrist below, the right-hand image has high contrast.
The left-hand image has poor contrast.
The ligament tear is much easier to see on the MRI with high contrast.
What do we use MRI arthrogram for?
We use contrast to help identify labral tears in the shoulder and hip, rotator cuff tears in the shoulder, ligament tears in the elbow, wrist and ankle and much more.
For many of these indications MRI arthrogram is the most accurate examination.
How is an MRI arthrogram performed?
Our radiologist will inject the joint with contrast or dye before the MRI examination using a needle. The patient will be then we escorted to the MRI suite for examination.
