Discogram
Discogram Testing for Back Pain Evaluation
A Discogram is an advanced diagnostic procedure used to identify whether a spinal disc is the true source of back pain. By injecting contrast dye into specific discs, physicians can clearly evaluate which disc is causing discomfort. At iMsk & Spine Group, this test helps us create a precise and personalized treatment plan based on accurate findings.
What Is a Discogram?
A Discogram, also known as discography, is a minimally invasive diagnostic test in which contrast dye is injected into one or more spinal discs while imaging is performed. If the injection reproduces a patient’s typical pain, the disc is likely to be involved in the condition. This information helps determine the right course of treatment moving forward.
Why It Helps
Discograms are especially useful when traditional imaging—such as MRI or X-ray—does not provide clear answers about the origin of pain. Understanding exactly which disc is problematic helps guide decisions about interventional or surgical options and supports more targeted care.
Conditions It Helps Diagnose
Discograms are commonly used in patients with:
- Chronic back pain
- Suspected disc degeneration
- Disc herniation
- Pain that has not responded to conservative treatments
- Diagnostic uncertainty even after MRI
How the Procedure Works
Discograms are performed under imaging guidance for safety and accuracy.
A typical procedure includes:
- Local anesthesia
- Imaging guidance (fluoroscopy or CT)
- Injection of contrast dye into the disc
- Pain response assessment
- Post-procedure imaging
You may feel temporary discomfort during the injection, which helps identify which disc is painful.
Discogram FAQ
Does a Discogram hurt?
You may feel pressure or discomfort during injection because the goal is to reproduce your typical pain.
Is a Discogram a treatment or a test?
It is a diagnostic test, not a treatment, used to determine the exact source of pain.
How long does the test take?
Most Discograms take 30–60 minutes depending on the number of discs examined.
What happens after the test?
Imaging results and your pain response are reviewed to guide your treatment plan.
Can this help avoid unnecessary procedures?
Yes—Discograms are often used to confirm whether more advanced intervention is necessary.
