Is there no solution to the back problem? Let's learn everything about the myelogram test!

Have you ever had back pain or pain that goes down your legs and you can't figure out what's causing it? You've probably seen a doctor and they've probably done tests like an X-ray, a CT scan, or an MRI. But what if they can't find anything clear? That's when a doctor might ask you to have a special test called a myelogram. Let's see what it is, how it's done, and what you need to know.

What is a Myelogram?

Simply put, a myelogram is a special test that takes detailed pictures of your spine. In this, a special liquid (contrast material) is used to clearly see problems with your spinal cord and the nerves and soft tissues around it. Think about it, a normal spine X-ray only shows the bones. Because it doesn't use this kind of special liquid. But in a myelogram, this liquid makes your spinal canal, spinal cord, and nerves look beautifully white on an X-ray or CT scan. This is like a technique called fluoroscopy. This means that your radiologist can see this liquid moving along your spine in real time.

You may have heard doctors call this a 'Cervical Myelogram' or a 'Lumbar Myelogram'. They are not different tests. They just mean which part of the spine they want to take pictures of. For example, if they want to look at the cervical section of your spine, it's called a cervical myelogram. If they want to look at the lumbar section of your spine, it's called a lumbar myelogram. Got it?

Why would a doctor order a myelogram?

If you have chronic back pain, your doctor will first order a CT scan or MRI to find the cause. However, if neither of those tests is clear, your doctor may recommend a myelogram to find out more.

There are several diseases that can be detected with this test. For example:

• Herniated / bulging disks: This is what we call a 'herniated disk'. This is when the soft tissue between the vertebrae bulges out and pinches the nerves.
• Arthritis in your spinal joints: This can cause swelling and pain in the joints.
• Spinal stenosis: This is when the space inside the spine narrows, causing the spinal cord or nerves to become compressed.
• Bone spurs / Osteophytes: The formation of small, spike-like growths on the bones.
• Spinal tumors.

Also, if you have recently had back surgery and have new, persistent pain or weakness, your doctor may order this myelogram test.

How does a myelogram work?

A myelogram can detect problems that a regular (CT) scan or (MRI) cannot. It is especially useful for clearly seeing if the bones, discs, and other tissues around the spinal canal are compressing the nerves or spinal cord.

When the radiologist injects a special liquid (contrast material) into your spine, the liquid travels through the space around your spinal cord. Your nerves and spinal cord appear as a silhouette on an X-ray or CT scan. This allows the doctor to find problems that a regular X-ray cannot.

How should I prepare for a myelogram?

Your doctor will give you a detailed list of things to do before your myelogram. However, in general, keep these things in mind:

• Talk to a trusted friend or family member to drive you home. (You may be given a sedative, so it's not a good idea to drive after the test.)
• Start drinking plenty of fluids (4-8 glasses) like water every two hours starting the day before the test.
• Stop eating six hours before the test. However, you can drink liquids such as water up to six hours before the test. Examples: water, unsweetened tea, clear soda, strong coffee, unsweetened fruit drinks, and soup broth.

If you have Diabetes Mellitus...

• Take your usual dose of insulin.
• When you come for your checkup, remind the doctor again that you have diabetes.

Usually, no lab tests are needed before a myelogram. However, if you have a history of blood disorders, a condition such as dehydration, or a long-term kidney disease such as Chronic Kidney Disease (CKD), your doctor may order blood tests.

What happens during a myelogram test?

You will not be put to sleep during a myelogram. However, you may be given some sedative medications to help you relax. A radiologist and technologist will be in the room with you the entire time.

During the test, they will do the following:

• You will be asked to lie down on an exam table (usually on your stomach or side).
• Your lower back area has been cleaned with antiseptic, and that's it.A numbing medicine (local anesthesia) is injected.
• Then, the contrast material is injected into the fluid-filled sac around your spinal cord. (You may feel a slight pressure or discomfort during this time.)
• The examination table is tilted back and forth slightly. This is to help the fluid flow properly through your spinal cord. The radiologist may also ask you to tilt or shake your head.
• Then, X-rays and CT scans of your spine are taken.

The whole process usually takes about an hour. There may be some discomfort or a slight headache.

What happens after a myelogram?

After the test , the doctors will monitor you for about an hour. They will then decide if you are ready to go home. They will give you written instructions about what to do after you go home. Your radiologist will send a detailed report to your primary care physician (PCP) or the doctor who referred you.

Are there any side effects of a myelogram?

About ten percent (10%) of people may experience side effects after a myelogram. Common side effects that resolve within a day or two include:

• Headaches.
• Nausea and vomiting.

However, if you have a headache that doesn't go away , or if you experience any of these dangerous symptoms , you should call your doctor immediately:

• Fever.
• Stiff neck.
• Tingling in your legs.

How long does it take to recover after a myelogram?

It usually takes about 24 hours. After a myelogram, you may need to sit or lie down for a few hours. Getting plenty of rest can help reduce the risk of a cerebral spinal fluid (CSF) leak. You can return to your normal activities after about a day. However, if your headache persists, or if you develop any other serious symptoms, such as fever, stiff neck, or numbness in your legs, you should definitely tell your doctor.

Here are some things you can do at home to help you recover:

• Try to keep your head higher than the rest of your body. Try to stay upright as long as possible.
• Drink plenty of fluids. Do not drink alcohol at all.
• For headaches, try something like acetaminophen and some caffeinated drinks (coffee, tea). These can sometimes help relieve the headache on their own.
• Do not lift any weights or engage in strenuous physical activity for 24 hours.

When will I know the results of the myelogram?

After you get the report from the radiologist, your primary care physician (PCP) or the doctor who referred you will review the test results. This usually takes a few days. They will then call you to explain the results and tell you what to do next.

When should I call the doctor after a myelogram?

After a myelogram, call your doctor immediately if any of the following occurs:

• Fever over 101 degrees Fahrenheit (38.3 Celsius).
• If you feel dizzy and feel like you might fall (fainting).
• If your legs are numb or you lose sensation (Tingling or numbness in your legs).
• If there is pain or discharge near the injection site.
• If the neck becomes stiff (Stiff neck).
• Headaches that won't go away.
• An inability to pee .

How painful is a myelogram?

The answer to this question varies from person to person. If the pain is unbearable, it's best not to come. However, you may experience some discomfort during the test, such as:

• It feels like a push when the special liquid (contrast material) is injected.
• As the needle is moved , a sharp, electric-like pain may suddenly appear along the buttock or leg .

Also, the contrast material can cause the following things:

• A warm or flushed feeling.
• A metallic taste in your mouth.
• Temporary nausea.

Your doctor and the team there will do everything they can to make you comfortable and get the test done quickly, so there's nothing to worry about.

Finally, what to remember (Take-Home Message)

Persistent back pain can take the fun out of your life and stop you from doing the things you love. When regular scans don't give you answers, it may be time to have a myelogram. This test can help your doctor figure out what's causing your discomfort and help you find a solution that works for you. So if a doctor suggests this test, talk it over, understand it, and go ahead with it. We hope you find relief from your problem soon!
