Inside the Spine: Exploring Myelograms for Comprehensive Diagnosis

Myelogram: A Comprehensive Guide to Spinal Cord Assessment and RisksHave you ever experienced back or spine problems? If so, you may be familiar with a myelogram.

This diagnostic procedure allows healthcare professionals to assess the condition of your spinal cord and the subarachnoid space surrounding it. In this article, we will explore the purpose of a myelogram and discuss the potential risks associated with it.

By the end, you will have a comprehensive understanding of this procedure and be better equipped to make informed decisions about your healthcare.

Purpose of a myelogram

Spinal Cord Assessment:

A myelogram is primarily used to assess the spinal cord and detect any abnormalities in its structure or function. It can help diagnose a range of conditions, including herniated discs, spinal cord tumors, infection, inflammation, spinal stenosis, ankylosing spondylitis, bone spurs, arthritic discs, cysts, spinal nerve root injury, and arachnoiditis.

Subarachnoid Space Assessment:

By injecting contrast dye into the subarachnoid space, healthcare professionals can visualize this area more clearly on X-rays or computed tomography (CT) scans. This allows them to identify any abnormalities that may be causing pain or discomfort in your back or spine.

Diagnostic Tool:

A myelogram is often recommended when other imaging tests, such as magnetic resonance imaging (MRI) or CT scans, are inconclusive or unable to provide sufficient information. It can provide valuable insights into the underlying cause of your symptoms and help guide your healthcare providers in developing an appropriate treatment plan.

How is a Myelogram Performed? A myelogram typically involves the following steps:



Before the procedure, you will be asked to remove any jewelry or clothing that may interfere with the X-rays. You may also need to fast for a few hours prior to the test, depending on your specific instructions.

It is essential to inform your healthcare provider about any allergies or medical conditions you have, as well as any medications you are taking. 2.

Injection of Contrast Dye:

Once you are properly prepared, a contrast dye will be injected into your subarachnoid space. This dye helps highlight the spinal cord and nerves during imaging.

You may feel a warm sensation or mild discomfort as the dye is being injected. 3.


After the dye is injected, you will be positioned on an X-ray table. X-rays or CT scans will be taken at various angles to obtain clear images of your spine.

It is essential to remain still during this process to ensure accurate results. 4.

Post-procedure Care:

After the procedure, you may be required to lie flat for a certain period to prevent complications. You will also be monitored for any immediate side effects or adverse reactions to the contrast dye.

Risks of a myelogram

Allergic Reactions:

One of the most significant risks associated with a myelogram is an allergic reaction to the contrast dye. While rare, it is essential to inform your healthcare provider if you have a known allergy to iodine or contrast agents.

Signs of an allergic reaction may include hives, itching, difficulty breathing, or swelling of the face, lips, tongue, or throat. If you experience any of these symptoms, seek immediate medical attention.


In some cases, a myelogram may trigger a seizure, particularly in individuals with a history of epilepsy or seizures. Your healthcare provider will evaluate your medical history and discuss the risks and benefits of the procedure with you before proceeding.

Cerebrospinal Fluid (CSF) Leak:

A CSF leak is a potential complication of a myelogram. If the needle used to inject the contrast dye punctures the dura, the protective covering of the spinal cord, it may lead to leakage of cerebrospinal fluid.

This can cause headaches, numbness, or even infection. Rest and hydration are usually recommended to help the body heal and restore proper CSF levels.


Some individuals may experience headaches following a myelogram. These headaches are typically mild and resolve on their own within a few days.

However, if the headaches persist or worsen, it is crucial to inform your healthcare provider. Infection:

As with any invasive procedure, there is a slight risk of infection.

Your healthcare provider will take precautions to minimize this risk, such as using sterile equipment and maintaining proper hygiene during the procedure. If you experience increasing pain, redness, swelling, or fever after the myelogram, it could be a sign of infection and should be promptly addressed by a medical professional.

Other Potential Risks:

While uncommon, other potential risks of a myelogram include numbness, lower back pain, bleeding, or complications specific to your medical condition. It is crucial to discuss these risks with your healthcare provider beforehand to ensure you are fully informed.


In this article, we have explored the purpose of a myelogram and discussed the potential risks associated with this procedure. A myelogram is a valuable diagnostic tool for assessing the spinal cord and subarachnoid space in individuals with back or spine problems.

While there are risks involved, healthcare providers take necessary precautions to minimize them. By understanding the purpose and risks of a myelogram, you can make informed decisions and actively participate in your healthcare journey.

Remember to consult with your healthcare provider for personalized advice and guidance.

Preparing for a Myelogram

Preparing for a myelogram is an essential step to ensure the success and safety of the procedure. Proper preparation can help minimize risks associated with infections, allergic reactions, and other complications.

In this section, we will delve into the various aspects of preparing for a myelogram, including medications, clothing, dietary restrictions, and other important considerations. Antibiotics and Infection Prevention:

Your healthcare provider may prescribe antibiotics before the myelogram to reduce the risk of infection.

This is particularly important if you have a history of spinal infections, are immunocompromised, or have undergone spinal surgery in the past. Make sure to follow the prescribed dosage and complete the entire course of antibiotics, even if you feel better before the myelogram.

Seizure Precautions:

If you have a seizure disorder or epilepsy, it is crucial to inform your healthcare provider beforehand. They may adjust your medications or provide additional seizures precautions during the procedure to minimize the risk of seizure activity.

Allergy Assessment:

Before the myelogram, your healthcare provider will assess your risk of allergic reactions to the contrast dye used during the procedure. If you have had a previous allergic reaction to iodine or contrast agents, it is important to inform your healthcare provider.

They will take necessary precautions or recommend alternative imaging methods if appropriate. Pregnancy Considerations:

If you suspect or know that you are pregnant, it is crucial to inform your healthcare provider before scheduling a myelogram.

While the procedure itself does not pose a direct risk to the fetus, certain medications and the use of X-rays can potentially harm the developing baby. In some cases, the procedure may need to be postponed or alternative imaging methods may be considered.

Anticoagulant Therapy:

If you are taking anticoagulant therapy, such as warfarin or aspirin, it is important to inform your healthcare provider. They may advise you to temporarily discontinue or adjust the dosage of these medications to reduce the risk of bleeding complications during the myelogram.

It is essential to follow your healthcare provider’s instructions carefully and inform them of any changes in your medication routine. Clothing Recommendations:
