Discography is a medical procedure that involves injecting a dye into the jellylike center of a spinal disc to help diagnose back problems.
During discography, a doctor looks at the amount of pressure needed to inject the dye into the disc, whether it causes pain that is the same as your regular pain, how much dye is used, and how the dye appears on X-ray after it is inside the disc.
Most people have changes to their spinal discs as they age, but these changes usually do not cause any symptoms.
Discography has been largely replaced by simpler and more effective methods for basic testing. It is sometimes still used in hard-to-diagnose cases or before surgery. Discography may increase the risk of having disc problems.1 Most experts no longer recommend it.2 If your doctor recommends discography, experts recommend getting a second opinion before having this test.
