Discogram: What You Need To Know
Discogram Overview and Purpose
A discogram is a diagnostic test that examines the spinal discs, which are gel-like cushions located between the bones in the spine. The purpose of a discogram is to identify painful discs to assist in planning treatment or surgery. It is utilized when other tests have not been successful in locating the source of pain.
During the procedure, dye is injected into the spinal discs, followed by the capture of X-rays or CT scans. The dye highlights damaged areas on these images, allowing for the identification of the disc(s) causing back pain, thereby aiding in the guidance of future treatments.
Risks and Preparation for a Discogram
A discogram is a diagnostic procedure that assists in identifying if a specific spinal disc is the source of pain. This procedure, like others, carries potential risks and requires preparation.
The most common risks include:
- Infection
- Bleeding
- Severe worsening of pain
- Nerve damage
Allergic reactions to the dye used during the procedure are rare. Discitis, an infrequent but serious complication, involves inflammation of the intervertebral disc space.
Adequate preparation is necessary before undergoing a discogram. It is important to be aware of medications being taken and any allergies. Certain medications, such as blood thinners and NSAIDs (Non-Steroidal Anti-Inflammatory Drugs), may need to be paused several days before the test. It is also important for no food or drink to be consumed for at least six hours prior to the procedure.
Arrangements for transportation after the test should be considered, as driving is usually not recommended due to temporary physical discomforts that may be experienced.
This overview provides information on the discogram, highlighting the importance of understanding the procedure's risks and necessary preparations.

Procedure and Interpretation of Discogram Images
A discogram is a diagnostic procedure that employs X-ray and a special dye to examine the intervertebral discs of the spine. The process involves the insertion of a needle into the suspected disc, followed by the injection of the dye, and then the capture of images, known as discograms.
- The procedure begins with local anesthesia.
- The patient lies down on an examining table.
- A doctor utilizes fluoroscopy, which are real-time X-rays, to guide a thin needle through the skin and muscle tissues.
- Upon reaching the correct location, contrast dye is injected into the disc.
Following the injection, several X-ray pictures, or discograms, are taken from different angles. These images illustrate how the dye disperses within each disk.
Interpreting Discogram Images involves analyzing the distribution of the dye, which can indicate conditions such as tears or ruptures in the discs.
- The leakage of dye from a damaged disk suggests potential damage to its outer layer, known as the annulus fibrosus.
- Conversely, if the dye remains contained, it is indicative of discs that likely do not have significant injuries.
- Additionally, the pain experienced during the injection might correlate with the source of discomfort.
Post-Discography Care and Reading Results
A discography is an imaging test of the spinal discs used to identify damaged or painful discs. Soreness may occur after the procedure.
- Rest is recommended for 24 hours following the procedure, along with increased fluid intake to aid in recovery.
- Pain management may include over-the-counter pain relievers. Heat or ice packs can also be applied to the injection site to soothe discomfort.
- It is important to monitor the condition closely, particularly at the injection site. Symptoms such as severe pain, fever, redness, swelling, or discharge from the injection area could indicate an infection.
Interpreting discography results involves distinguishing between normal and abnormal findings.
- A normal result is indicated by the dye remaining within the disc borders. An abnormal result, where the dye extends outside the disc borders, suggests damage to the disc which may be the source of pain symptoms.
The results are typically discussed during a follow-up appointment, where a treatment plan may be outlined based on the findings.
Discogram's Role in Back Pain Treatment and Controversies
A discogram is a diagnostic test used to identify painful discs in the spine, which are often implicated in back pain. The procedure involves the injection of dye into the spinal disc to enhance visibility on an X-ray.
The utility and safety of discograms are subjects of controversy within the medical community. Critics argue that the procedure might exacerbate damage to already compromised discs.
Research on the effectiveness of discograms for diagnosing the causes of back pain yields mixed results. While some studies find them to be beneficial, others do not support their use.
Risks associated with this procedure include:
- Infection
- Nerve damage
- The potential worsening of pre-existing pain.
Considering these factors is important in the context of treatment planning for back pain.
