This arthrogram of the shoulder shows a rotator cuff tear.

An arthrogram is an x-ray of the joints. A contrast media is used to more clearly visualize the joint.

Preparing for an Arthrogram

If the examination is scheduled for the morning, you may drink or eat clear liquids 2-3 hours before the scheduled time of the test. You should also take your regular medication at that time. If the exam is scheduled in the afternoon, you may eat a full breakfast and then have clear liquids two hours before the scheduled time of the test, and take your regular medications.
