Conditions + Treatments. MRI Arthrogram. An MRI arthrogram is an imaging procedure that obtains pictures of your child's joint after a contrast material has been injected into it, allowing the radiologist to see the soft tissue structure of your child's joint. An MRI arthrogram is a two-part procedure: 1  A special type of x-ray technology, called fluoroscopy, is used to take pictures of the joint during the first part of this procedure. 2  After the fluoroscopy, your child will receive an MRI to obtain additional images of the joint.
MRI stands for magnetic resonance imaging; it basically uses powerful magnets and radio waves to create detailed images of the interior of your body. It can be done with or without contrast. Contrast is a type of dye that is injected intravenously either right before, or during the procedure. Certain abnormalities, such as tumors, will absorb the dye and show up very clearly on the MRI with contrast. Your doctor will determine whether you need an MRI with contrast or without, and may order both tests. An MRI scan is different than a regular x-ray or a CT scan, which both use ionizing radiation to create images. MRI scans generally produce clearer images with much more detail than an x-ray or CT scan.
