Arthrography (Arthrogram)

An arthrogram is the examination of a joint using X-ray. The most common areas studied include the shoulder, knee, or hip. During the examination, the radiologist, a physician who specializes in medical diagnosis through X-ray, injects a special dye (contrast medium) into the joint space while watching with the X-ray machine. An X-ray technologist will assist in the exam.

Procedure: What you can expect During the Arthrogram?

The technologist will bring you to the exam room. The procedure will be explained to you and you will be asked to sign a consent form.

You will lie on your back on the X-ray exam table. The area around your joint will be washed with antiseptic soap and covered with a sterile drape or towel.  The radiologist will use a small needle to numb (anesthetize) the area being examined.

A special needle is then inserted into the joint space and the x-ray dye is administered. This dye will coat the structures of the joint making them visible under X-ray

The radiologist will remove the needle. Then he will ask you to hold various positions while X-ray films are taken.

Afterwards

Your joint may feel tight or slightly painful after the exam. This is normal and should not be cause for concern. Moving or exercising the joint will help this feeling to pass. If you experience prolonged pain following the exam you should contact your doctor.

Depending on your doctor...

• A CT scan or MRI may follow your arthrogram
• Your doctor may leave other instructions for you to follow relative to your health history

The radiologist will study your test and provide your doctor with a detailed report. Your physician will then discuss the results with you.
