CT Arthrogram

CT Arthrogram of the shoulder

A CT arthrogram is a diagnostic study of the joint structures within the body by injection of x-ray contrast (dye).

As the dye disperses, the radiologist documents whether the dye is contained or is leaking, which indicates the stability and integrity of the joint and reveals cartilage tears and other injuries. An arthrogram is sometimes performed as a sole diagnostic test. If the site and nature of the injury are clearly apparent, the diagnostic process may stop here.

In other cases, arthrography can be the first phase of a diagnostic process that also includes CT or MRI scans. At the time of the procedure, your provider will allow you the chance to ask any questions you may have. You will be asked to sign a consent for treatment.


What to Expect

What is a CT Arthrogram used for?

Your doctor may order a CT Arthrogram if they suspect damage to your joints, such as a tear in the ligaments or muscles.

Are there any serious risks?

Typically, no. Some patients may experience a reaction to the contrast dye, but these occasions are rare. Please contact our offices if you suspect or have had a reaction to contrast dye in the past.
