An arthrogram is a series of images, often X-rays, of a joint after injection of a contrast medium. The injection is normally done under a local anesthetic.
The radiologist performs the study utilizing fluoroscopy or ultrasound to guide the placement of the needle into the joint and then injects the contrast. A physician or technologist obtains a series of X-rays, or alternatively computerized tomography (CT) scans or Magnetic resonance imaging (MRI) scans. The joint can be imaged from many angles in fluoroscopy, or on a slice by slice basis in CT and MRI scans. The physician assesses the images produced.
The shoulder, hip, knee, ankle and wrist are the joints most commonly evaluated by Arthrogram procedures.
