Arthrography is a type of X-Ray examination that uses a contrast
agent to image an anatomical joint, such as the knee, shoulder, elbow or
wrist.
An MRI arthrogram is an imaging procedure that
demonstrates the structures of the joint, including cartilage, ligaments
and bursa (the fluid-filled joint capsule) allowing the radiologist to
assess the anatomy and function of the joint. An MRI arthrogram is needed when a
problem with the joint cartilage is suspected.
The procedure is also used to help diagnose persistent,
unexplained joint pain or discomfort.
