This outpatient procedure is a diagnostic examination of the spine. A special x-ray-sensitive contrast dye is injected to illuminate the spine, allowing identification of problems of the spine, spinal cord and nerve roots.
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.
