Arthrography is a type of imaging test used to look at a joint, such as the shoulder, knee or hip. It may be done if standard X-rays don't show the needed details of the joint structure and function.
In arthrography, a long, thin needle is used to put contrast dye right into the joint and a series of X-rays is taken with the joint in various positions. X-rays use small amounts of radiation to get pictures of the inside of the body. Sometimes air is used as the contrast substance when regular contrast can't be used.
An arthrogram may also use fluoroscopy, CT or MRI instead of X-rays to get better pictures of the joint.
While arthrography is most commonly used to examine the knee and shoulder joints, it may also be used to look at other joints, such as the wrist, ankle, hip or elbow.
