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.
The MRI machine itself contains a large magnet. Hydrogen atoms (i.e., protons) in the brain rotate themselves to a particular orientation with respect to the magnet. The MRI machine records the radio frequencies emitted by the hydrogen atoms. MRI scanning results in high-resolution structural images of the brain.
