Arthrogram

An arthrogram is an imaging study used to assess your joint problem. Contrast fluid is injected into the joint being studied. Then, X-ray, computed tomography (CT), or magnetic resonance imaging (MRI) is used to create images.

How do I get ready for an arthrogram? 

• Arrange for someone to drive you home.

• Wear loose-fitting clothing.

What happens during the arthrogram?

• X-rays of your joint are taken first.

• The skin around the joint is cleaned and then covered with drapes.

• The area around your joint is usually numbed with a local anesthetic.

• The area around your joint is numbed.

• The radiologist inserts a needle into the joint, using fluoroscopic or ultrasound guidance. A sample of joint fluid may be removed. 

• Contrast fluid is injected into your joint to improve the images.

• X-rays are again taken.

• The doctor will move your joint. You will also be asked to exercise your joint.

• Additional X-rays may be taken after you exercise.

• If you need a CT or MRI test, it will follow the X-rays.

What happens after an arthrogram? 

• Drink extra water or other clear fluids for 24 hours.

• Vigorous exercise is not recommended for 24 hours after the arthrogram.

• You may have swelling and discomfort in the involved joint after the procedure. You may apply ice to the joint or use an over-the-counter pain reliever.

What are the risks of arthrogram?

• This procedure uses medical X-ray radiation. The amount of X-ray exposure is felt to be low and safe.

• There is a small risk of pain, bleeding, or infection at the injection site.
