Arthrography assesses bony joints such as; the hip, shoulder, ankle or knee. Any excess joint fluid might be withdrawn with a needle before contrast media is injected. After the contrast is injected, the patient might be asked to move the joint around to evenly distribute the contrast within the joint.
Injecting contrast media and/or air into a joint space enables the radiologist to assess the cartilage, ligaments, tendons and other structures. Once the contrast has been introduced into the joint more detailed images are acquired using fluoroscopy, CT or MRI.
Patients will be instructed to cease any blood thinners, and arrange transportation to and from the appointment.
