A CT arthrogram is a two-part procedure performed to aid in the diagnosis of subtle abnormalities in the joints of the extremities, including the shoulder, elbow, wrist, hip, knee and ankle.
If you have an active infection and are taking antibiotics, the medication course must be complete prior to the procedure, to ensure that no infection remains.
Wear comfortable clothes without metal fasteners, including zippers, buttons and snaps.
Arrive 15 minutes early to complete registration.
Bring with you: – Your appointment form – Your insurance card and a valid photo ID
Please let us know about any of the following: – Pregnancy, known or possible – Allergies to medications, iodine or x-ray contrast
Please let us know if you have an insulin pump or glucose monitor. Our imaging machines may cause your device to malfunction, so it will need to be removed during your exam.
How long will my exam take?
A CT arthrogram typically takes about an hour: 30 minutes for the injection and 30-45 minutes for the CT scan.
What happens during my exam?
During the first part of a CT arthrogram, contrast is injected into the joint space under x-ray guidance. The contrast material serves to illuminate the joint space during imaging.
The second part of a CT arthrogram is to capture images of the joint.
What happens after my exam?
Your images will be interpreted by one of our board-certified radiologists. The findings will be sent to your healthcare provider who will then contact you to discuss the results.
