Discography in addition is labeled as discogram is presently used to establish whether the disk is the cause of pain in patients with primarily axial back or neck pain. The doctor injects a dye into a specific disc to reveal damage on an X-ray image.
A doctor may choose discography for patients with persistent pain when other imaging methods have failed to precisely locate the source of pain. A discogram is most commonly done prior to a lumbar fusion surgery. Discography should be completed only if sufficient attempts at moderate therapy and noninvasive diagnostic tests, such as MRI, have failed to expose the etiology of back pain.
The lumbar discography is usually an outpatient procedure. It is likely to take about three hours total, while the procedure itself takes about 30 to 60 minutes, depending on the number of discs planned for testing.
