Post CT Arthrogram

CT Arthrography allows joint structures to be viewed in ways which traditional CT scanning would not be able to capture. CT Arthrogram provides high quality images of a joint by utilizing a CT unit and a contrast fluid. The fluid outlines internal joint structures, such as cartilage and ligaments. The term “Arthrogram” refers to the injection, while the CT study is conducted immediately following the injection.

Who Needs This Procedure?

CT Arthrography is a good alternative to patients who would have contradictions with an MRI scanner. These contradictions, such as permanent metal implants in the body, would complicate an MRI scan.

Preparing For The Procedure:

If you have any removable metal objects, such as eyeglasses, jewelry, dentures or hair accessories, remove them before the CT scan. These objects may affect the CT images. Removable hearing aids and dental work should also be removed before the test. Women should inform their physician if there is a chance they may be pregnant.

During The Procedure:

The patient will lie flat on an exam table. You will be administered an arthrographic injection to the joint in question. A technologist will position the patient as needed. The patient will be asked to hold still for optimal imaging. The exam table will then slide into the open machine, and the imaging begins. Once the CT scan is complete, the technologist will then slide the patient out of the CT unit.

What Will I Experience?

Unlike MRI, CT scanning causes minimal noise that is only heard during scanning. The injection causes little to no pain, though you may feel pressure at the site. CT scanning causes no discomfort, and is a very quick procedure, often taking just seconds once the patient is positioned. The scan utilizes a special form of X-ray technology, however, radiation dosage to the body is very small.

The Benefits:

Arthrography is beneficial in that it allows imaging of joint tearing and abnormalities. CT scanning is a non-invasive method of diagnosis for symptomatic patients with issues that require a view inside the body. It is a short, painless procedure and emits very low amounts of radiation.
