CT Arthography

CT arthrography is an imaging technique used to study the internal structure of joints, including the cartilage, ligaments, joint lining and the structures around the joint, including the tendons, muscles and bones.

To determine the severity of and course of treatment for joint injuries caused by trauma, infection, overuse or arthritis.

A contrast agent is injected into the joint to coat the structures and provide the radiologist with detailed cross-sectional images of the injured or affected joint.

You may be asked to remove some clothing and put on a gown. A radiologist or technician will meet you in the X-ray room and explain the procedure. Your skin will be cleaned with an antiseptic solution and a small needle will be placed into the joint using X-ray or ultrasound guidance. Iodine contrast fluid is then injected into the joint. You may feel some pressure and fullness in the joint but it should not be painful. You will then be taken into the exam room where a scan of the joint will be performed. You should allow up to one hour for the whole procedure to be completed and for you to be dressed and ready to leave. The images will be reviewed and reported to your referring physician.

You may experience some swelling and discomfort of the injected joint for one to two hours after the injection. This should quickly resolve. If pain persists beyond 24 hours please consult your doctor.

Report to your radiologist or technician any known allergies or if you are or could be pregnant.
