Discography, also called discogram, is a diagnostic procedure used to determine if back pain is caused by one or more discs. The procedure involves pressurizing discs with an injection of sterile liquid to induce pain in the affected discs. Discography helps the specialist plan a course of treatment.
In this minimally-invasive procedure a flexible instrument containing a tiny camera, called an epiduroscope, is used to diagnose the cause of pain in the lower spine and legs, likely from sciatica. During the procedure, the physician may also administer medication to treat the pain.
