Overview

What is Discography?

Discography, also known as discogram, is a diagnostic procedure used primarily to determine the source of back pain. This technique helps to identify which disc might be causing pain by stimulating the disc with an injection and then using imaging techniques to view the disc’s response. This is particularly useful in cases where other imaging tests, such as MRI or CT scans, have not conclusively pinpointed the pain source.

Where on the Body is Discography Done?

Discography is most commonly performed on the intervertebral discs of the spine, particularly in the lumbar (lower back) and cervical (neck) regions. These are areas prone to degenerative disc issues and other disc abnormalities that might cause pain.

How does Discography Work with other Treatments?

Discography is typically used when the pain management plan is not clear because the exact source of pain is unknown. It is a diagnostic rather than therapeutic procedure, so it often precedes other treatments:

Surgical Planning: Discography can confirm whether a disc is problematic before surgical interventions such as a discectomy or spinal fusion are performed.
Targeted Therapy: Knowing which disc is problematic allows for more accurately targeted treatments, such as steroid injections or nerve blocks, aimed specifically at the affected area.
Treatment Efficacy Evaluation: After other treatments are administered, discography might be used to assess their effectiveness, particularly in complex cases with mixed results.
