X-ray - joint; Arthrography; Arthrogram
How the test is performed
The test is done in a hospital radiology department or in the health care provider's office. The x-ray technologist will help you position the joint to be x-rayed on the table. Once in place, pictures are taken. The joint may be moved into other positions for more images.
How to prepare for the test
Tell the health care provider if you are pregnant. Remove all jewelry before the x-ray.
How the test will feel
The x-ray is painless. It may be uncomfortable to move the joint into different positions.
Why the test is performed
The x-ray is used to detect fractures, tumors, or degenerative conditions of the joint.
What abnormal results mean
The x-ray may show:
- Bone tumors
- Degenerative bone conditions
- Osteomyelitis (inflammation of the bone caused by an infection)
The test may also be performed to find out more about the following conditions:
- Acute gouty arthritis (gout)
- Adult-Onset Still's disease

What the risks are
There is low radiation exposure. X-ray machines are set to provide the smallest amount of radiation exposure needed to produce the image. Most experts feel that the risk is low compared with the benefits. Pregnant women and children are more sensitive to the risks of the x-ray.
