An Arthrogram is an x-ray study of the joints, usually performed in the shoulder, knees, etc. This exam is mainly done to see if you have tears or rips in the various connective tissues that help make up a well working joint.

The radiologist will start the procedure by cleaning the skin over the joint in order to prepare a sterile field for the exam. He will then use local anaesthetic to numb the skin over the joint. Then a small needle is inserted into the joint using a fluoroscope to guide the procedure. A small amount of contrast is then injected into the joint, and a series of films, using both fluoroscopy and plain x-rays , will be taken of the joint. The radiologist then reviews the films taken and makes the decision whether or not additional images or CT scan are needed. Other than the restrictions that your physician has advised, you will not need to take any additional safety precautions other than to be extra careful in moving the joint studied.

No special preparation required. Since some joint discomfort may occur, bring a friend or relative who can drive you home.
