Discography means imaging of the intervertebral discs by intradiscal contrast injections. Discography with a combined CT/discography allows a more detailed classification of annular disruption and degeneration. Combined with a pain response registration, discography can be of value in the diagnosis of chronic low back pain with signs of sciatica in cases where other x-ray modalities have failed to explain the source of pain. Among 20 discography examinations there was a correlation between radicular symptoms and annular disruption with contrast leakage to the epidural space, and disc protrusion on CT scanning. |
