Arthrogram
Arthrogram
An Arthrogram (/ɑːrθrəɡræm/; from Greek arthro- meaning joint, and -gram meaning record) 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 or radiographer may use imaging guidance to place the needle into the joint and to ensure that it is in the correct location.
Procedure
The procedure for an arthrogram involves the injection of a contrast medium into the joint. This is usually done using a fluoroscope to guide the needle into the joint. Once the contrast medium is in place, a series of images are taken using X-ray, CT, or MRI. The images can then be used to identify any abnormalities in the joint, such as tears, degeneration, or disease.
Uses
Arthrograms are used to diagnose conditions affecting the joints. These may include rheumatoid arthritis, osteoarthritis, and gout. They can also be used to assess the extent of injury to a joint following trauma, such as a fracture or dislocation.
Risks
As with any medical procedure, there are risks associated with an arthrogram. These may include infection, allergic reaction to the contrast medium, and damage to the joint or surrounding tissues. However, these risks are generally low and the procedure is considered safe for most patients.
