What is an Arthrogram?

An arthrogram is an x-ray examination of the joint using fluoroscopy and an injection of a contrast material allowing the radiologist to assess the anatomy and function of the joint. Fluoroscopy uses radiation and an image intensifier that converts x-rays into a video image.

Common Joints Arthrograms are used for:

• Shoulder
• Wrist
• Hip
• Knee
• Ankle

How to prepare for the procedure:

No prep is needed. Please inform your physician of any medication you are taking and if you have any allergies, especially to contrast materials. You will be asked to change out of some of your clothes and put on a gown. Do not wear jewelry to your exam. Women should inform their physician or radiographer if you maybe or are pregnant.

How is the procedure performed?

The patient is positioned on the x-ray table, usually lying on your back. The radiologist (physician who performs the arthrogram procedure) will then asked you a few questions to make sure you have no allergies to the material that will be injected in your shoulder and you are comfortable with the procedure. The skin (on the body part to be injected) is cleaned with an antiseptic and the radiologist will locate the joint space. A local anesthetic is injected into the area. The radiologist will then proceed to inject the contrast material into the joint space. The radiologist will then remove the needle and ask the patient to move their joint as they take x-rays.

MRI or Cat Scan Arthrograms:

Many Arthrograms are combined with an MRI and sometimes with a CT Scan. You can refer to the website under MRI and CT for additional information on what to expect in these modalities.

What will I experience during and after the procedure?

Initially, you will feel a slight prick and burning sensation as the anesthesia is injected. After that you may feel fullness in the joint and it may be uncomfortable. You may apply ice over the joint to reduce swelling if it occurs. The discomfort may last up to 2 days. If the discomfort lasts longer than 2 days, please contact your doctor.

Who interprets the results and how do I get them?

The radiologist is specifically trained to perform your exam and also interpret your exam. The radiologist will review your images and send a signed report the physician who requested your exam, who will then share the results with you.
