An arthrogram is a test using X-rays to obtain a series of pictures of a joint after a contrast material (such as a dye, water, air, or a combination of these) has been injected into the joint.
It is often used in conjunction with MRI, especially if looking fro:
assessment of the integrity of the rotator cuff
assessment of shoulder instability
for diagnosis of glenoid labrum tear
for diagnosis of adhesive capsulitis
Shoulder Arthrograms are now offered at CMRI-CT!
