What is an Arthrogram?
An arthrogram is a type of x-ray examination that uses a contrast agent to image structures within a joint, such as the knee, shoulder, elbow, or wrist. An arthrogram demonstrates the structures within the joint, such as the cartilage and ligaments. The test may be ordered when a patient suffers an injury to a joint or if the joint feels stiff, painful or ”locked.” In some cases magnetic resonance imaging (MRI) or computed tomography (CT) are used in addition to arthrography.
How is the procedure performed?
A thin needle will be positioned within the joint by means of fluoroscope, and then inject the contrast into the joint.
The second stage of the exam involves imaging of the joint. You may be placed in either the MRI or CT scanner for a series of images. It is important to remain motionless so that small details within the joint can be captured. The imaging portion of the exam takes approximately 30 minutes.
Is the procedure painful?
During the injection of the contrast, you may feel some slight pressure or discomfort as the joint is distended. The sensation is temporary and will pass within a short time after the procedure. Some soreness may also be present at the injection site for up to 24 hours.
How should I prepare for the procedure? - Do not eat solid foods for three hours prior to the examination.
- If taking anticoagulants (Coumadin, Plavix, Ticlid), your healthcare provider may ask you to stop taking them five days prior to the exam and resume taking them the morning after the procedure. Contact your healthcare provider before stopping any medications.
- If you are on antibiotics for an infection, your medication must be completed before the procedure.
What should I do after the procedure?
You may resume regular activities immediately after the procedure. It is recommended that you limit strenuous or “stress-bearing” activities on the affected joint for 24 hours following the procedure.
