What Is Discography?
Discography — also called a provocative discogram — is a diagnostic procedure used to determine whether a specific intervertebral disc is the source of your chronic back pain. Unlike MRI, which shows the structural appearance of your discs, discography tests how each disc actually behaves when pressurized, revealing whether it reproduces the exact pain you experience in daily life.
This distinction is critical because MRI findings often do not correlate with symptoms. Many people have disc abnormalities on MRI — bulges, herniations, degeneration — that cause no pain at all. Conversely, a disc that looks relatively normal on MRI may be the actual pain generator. Discography bridges this gap by identifying which disc is causing your pain, guiding treatment decisions with much greater precision.
Discography is not a treatment — it is a diagnostic tool. The results help Dr. Qureshi and your care team determine whether interventional procedures, surgical options like fusion, or continued conservative management is the most appropriate path forward.
When Is Discography Recommended?
Discography is typically recommended when three conditions are met:
You have chronic back pain lasting 3–6 months or longer that has not responded adequately to conservative treatments including physical therapy, medications, and injection-based therapies.
MRI shows disc abnormalities at multiple levels and it is unclear which disc (or discs) is responsible for your symptoms. This is common — many patients have degeneration or bulging at two, three, or even four levels, but only one or two may actually be causing pain.
A treatment decision depends on identifying the exact pain source. This is most relevant when spinal fusion surgery is being considered. Surgeons need to know precisely which levels to fuse, and discography provides this information with a level of certainty that MRI alone cannot.
Discography is not a first-line test. It is reserved for patients with persistent pain where the diagnosis remains uncertain despite thorough imaging and clinical evaluation.
How Discography Is Performed
Before the Procedure
You will receive specific instructions about medications, eating, and transportation. You should not take pain medication on the morning of the procedure — your natural pain response needs to be intact for the test to be accurate. Antibiotics are typically administered before the procedure to minimize infection risk.
During the Procedure
Discography is performed under fluoroscopic (live X-ray) guidance with local anesthesia and light sedation. You remain awake enough to communicate your pain response — this is essential because your feedback is the entire point of the test.
Dr. Qureshi inserts a thin needle into each disc being tested, one at a time. A small amount of contrast dye is injected under controlled pressure. As each disc is pressurized, you are asked two key questions: does this reproduce your typical pain, and where do you feel it?
A "positive" disc is one where pressurization reproduces your concordant pain — the same type, location, and quality of pain you experience day to day. A "negative" disc is one where pressurization causes only pressure sensation or a different type of pain. At least one negative (control) disc is tested to validate the results.
After injection, the contrast dye also reveals the internal structure of the disc on fluoroscopy and subsequent CT imaging, showing annular tears, fissures, or disruption patterns that may not be visible on MRI.
After the Procedure
You will likely experience increased back pain for 2–5 days following discography, which is normal and expected. This temporary flare is managed with ice, rest, and prescribed pain medication. You should arrange for someone to drive you home. Most patients return to normal activities within 3–5 days.
A post-discography CT scan is often performed within a few hours to provide detailed images of the disc structure combined with the contrast dye.
Understanding Your Results
Discography results are classified for each disc tested:
Concordant positive: Pressurization exactly reproduces your typical pain. This disc is very likely a significant pain generator and a potential treatment target.
Discordant positive: Pressurization causes pain, but it is different from your typical symptoms in location, quality, or intensity. This disc is less likely to be the primary source.
Negative: Pressurization causes only pressure sensation without significant pain. This disc is unlikely to be contributing to your symptoms.
Dr. Qureshi will review your results in detail and discuss what they mean for your treatment plan. If a positive disc is identified, treatment options may include targeted epidural steroid injections, intradiscal procedures, radiofrequency ablation of the disc, or surgical referral for fusion or disc replacement depending on the clinical picture.
