MRI Arthrography

An MRI arthrography is an MRI examination in which a contrast agent is previously injected into a joint: knee, shoulder, ankle, etc. The contrast fluid ensures that the images of the MRI scan are clearer and provide more detailed information. Because we need to inject the contrast fluid at the exact location, we do perform the injection on an examination table using X-rays (fluoroscopy).

What about pregnancy?

X-rays can be harmful to the unborn child. If you are pregnant or could be, discuss with your doctor whether the examination can be postponed or should be replaced by another examination. Always report this to the medical imager before the examination.

Course

Before the examination

An arthrography is done by appointment only.

The examination is only carried out on the basis of a medical prescription.

Please note that the investigation may start later than planned due to unforeseen circumstances.

To register, please go directly to the Radiology / Medical Imaging desk with your identity card and medical prescription. You should take with you images and/or access codes from relevant previous studies that were conducted elsewhere.

If you are allergic to gadolinium-containing contrast agents, please inform the reception staff at the counter, doctor, or nurse in advance. In this case, you will receive specific preparation that starts 24 hours before the examination.

During the examination

The examination starts on the X-ray table (fluoroscopy).

You will lie on an examination table. The medical imager ensures that you are in the correct position for the injection, usually on your back. An arthrography of the wrist or elbow can be done while sitting or lying on the stomach, and an arthrography of the ankle can be performed on the back or on the side.

The radiologist will gently puncture the joint with a fine needle and inject the contrast fluid into the joint (intra-articular).

After the injection, a medical imager will accompany you to the waiting room of the MRI department. The final imaging of the joint is done in the MRI scanner.

The complete examination (preliminary injection and subsequent MRI scan) can take up to 30 minutes.

After the examination

After the examination, you may experience a tense and/or unstable feeling in the punctured joint for several hours. This will gradually improve, after which you can resume your daily activities.

The radiologist will make a report of all the imaging findings of the examination.

When the examination is completed, you will receive a code/link with which the images and the report can be viewed by yourself and the requesting doctor. You will then discuss the results of the examination afterward with the requesting doctor or another specialist on the basis of this radiological report.
