Discography is a diagnostic test that uses live X-ray guidance to help pinpoint whether a specific spinal disc is the source of your back or neck pain, so your physician can plan the most appropriate next step in your care.
OVERVIEW
What discography is and how it works
Discography, also called provocation discography, is a diagnostic procedure used to help identify a painful intervertebral disc when imaging such as MRI shows changes at more than one level but cannot confirm which disc is actually generating your symptoms. It is a diagnostic test rather than a treatment, and it is most often considered when a targeted intervention or spine surgery is being planned.
During the test, a physician uses fluoroscopy (live X-ray) to guide a thin needle into the center of one or more discs. A small amount of sterile contrast dye is then injected to gently pressurize each disc. If injecting a disc reproduces your familiar, typical pain, that disc is considered a likely “concordant” pain generator; a disc that does not reproduce your usual pain when pressurized is less likely to be the source. The way the contrast spreads is also imaged, often followed by a CT scan, to show the internal structure of the disc and any tears in its wall.
Because the goal is to recreate and map your pain, discography can add functional information that a static MRI alone cannot provide. Our dual board-certified, fellowship-trained physicians in Gresham and Portland, Oregon use these findings to help confirm a diagnosis and inform decisions about further treatment or surgical planning.
CONDITIONS
What discography helps evaluate
Discography is used to investigate suspected disc-related pain in the lumbar (low back), thoracic (mid back), or cervical (neck) spine. It is typically considered after a thorough evaluation, when the specific painful disc still needs to be confirmed. The list below is representative, not exhaustive.

What to expect during discography
Before
You will review your current medications with our team, as blood thinners may need to be adjusted in advance. Let us know about any allergies, active infection, bleeding disorder, or the possibility of pregnancy. Because contrast dye is used, the procedure is performed in a sterile setting, and you should arrange for someone to drive you home.
During
You lie on a procedure table, and the skin is cleaned and numbed with local anesthetic. Using fluoroscopic guidance, the physician advances a thin needle into the targeted disc and injects contrast to pressurize it. You stay awake and communicate what you feel so the team can record whether each disc reproduces your typical pain. One or more discs may be tested, and a comparison disc that is believed to be healthy is often included.
Image guidance and duration
Discography relies on fluoroscopy for precise needle placement, and a CT scan is frequently performed afterward to examine the internal structure of the disc. The test itself commonly takes roughly 30 to 60 minutes, depending on how many disc levels are studied.
After
You will be monitored for a short period before going home. Because the test deliberately provokes the disc, it is normal to have increased back or neck soreness for a day or two; rest, activity modification, and ice are commonly recommended. Most people return to their usual activities within a day or two. Your physician will review the findings with you and discuss next steps, which may range from therapeutic injections to a procedure or a surgical consultation.

Related procedures and next steps
Discography is one of several diagnostic and interventional tools we offer. It is closely paired with percutaneous disc decompression and other disc procedures, and it complements our broader diagnostic services such as EMG and nerve conduction studies. Depending on what discography reveals, your physician may recommend spinal injections, another targeted procedure, or a surgical consultation.

Frequently asked questions
Will discography treat my pain?
No. Discography is a diagnostic test, not a treatment. Its purpose is to help identify whether a specific disc is causing your pain so your physician can recommend the most appropriate therapy or surgical plan. Any temporary soreness afterward comes from the test itself, not from a therapeutic effect.
Why do I need to be awake during the procedure?
Your feedback is the key part of the test. Because the goal is to reproduce your familiar pain, you need to be alert enough to tell the team whether pressurizing a particular disc recreates the pain you normally experience. You will still receive local numbing medication for comfort.
How is discography different from an MRI?
An MRI shows the structure and appearance of your discs, but it cannot always confirm which disc is actually generating your pain. Discography adds functional information by provoking each disc to see whether it reproduces your symptoms, which is especially useful when an MRI shows more than one abnormal-looking disc or when a lumbar fusion is being considered.
