Definition of Discography (discogram)
Medically reviewed by Dr. Otari Nergadze, Neurosurgeon | Updated: January 2026
Discography (discogram): an interventional diagnostic imaging test used to help identify the source of back pain and to guide the treatment of abnormal discs. Using X-ray guidance, contrast dye is injected into the center of one or more spinal discs, which can temporarily reproduce back pain symptoms and help diagnose if a particular disc is causing back pain. Discography may also be used before back surgery to identify discs that may need to be removed.
