CT of the Extremities
What is a computed tomography (CT) scan?
A computed tomography (CT) scan is a noninvasive exam that, compared with a standard X-ray, provides enhanced clarity and detail.
Why has my physician ordered this exam?
Usually, physicians call for this kind of CT to help assess the presence and extent of fracture or trauma. Your physician may also use this exam plus arthrogram to evaluate injury to a joint or joints.
Although IV iodinated contrast media is not usually necessary for this procedure, your physician may call for it to help monitor postsurgical changes and check for infection.
