What is a Myelogram?

A myelogram is a diagnostic imaging test usually performed by a radiologist. It uses contrast dye, X-rays, or computed tomography (CT) to check the spinal canal for problems. Problems can arise in the spinal cord, nerve roots, and other tissues. This form of test is also referred to as myelography.

Before the procedure, contrast dye is injected into the spinal column. Upon the X-ray screen, the contrast dye allows the radiologist a better view of the spinal cord, the subarachnoid space, and the surrounding areas than standard X-rays of the spine.

The radiologist will also need to use a CT scan when doing a myelogram. A CT, or CAT, scan is an imaging test that uses X-rays and a computer to create detailed images of the body. A CT scan produces detailed images of the spinal canal. CT scans reveal more detail than standard X-rays.

How do you perform a myelogram?

It possesses certain advantages over a CT scan or MRI, which cannot be performed with regular imaging non-invasive techniques. This is particularly effective regarding the abnormal bony structures, discs, and soft tissues within and around the bony canal free of the intruding structures, hence the spinal canal where these structures disturb the spine.

So when the radiologist injects contrast dye, some of the injected dye will swim through the cavity surrounding your spinal cord. In this case, the contours of the nerves and spinal cord located in the region of the patient s spine will be portrayed on the X-ray or CT images as a shadow. Thus, the medical provider gains access to information that is not obtained with a standard X-ray.

How do I prepare for a myelogram?

Your doctor will provide you with specific pre-procedure instructions. Meanwhile, follow these general guidelines:

• Do not eat or drink anything 6 hours before the exam. You may take medications with a small amount of water.
• Outpatients, please arrive 60 minutes before the scheduled exam time.
• The technologist will confirm your identification and the exam you are requesting.
• You can explain any aspect of the proposed plan to the radiologist and verbally accept consent.
• Bring any X-rays, CT scans, or MRI scans of your spine or brain.

What are the possible side effects of a myelogram?

10% of patients may experience side effects from a myelogram. Common side effects that should resolve in less than a day or so include

• Headaches.
• Nausea with vomiting.

Also, make sure to contact your doctor immediately if you have persistent headaches or any concerning symptoms, such as

• Fever
• Stiffness of the neck
• Numbness of your legs.

How long does it take to recover from a myelogram?

Typically this process lasts sixty minutes or so. After tests conducted for myelography, you are probably going to be in a sitting or reclining position for a day or two. Resting lowers the chance of developing a cerebral spinal fluid leak. Once you're feeling well, you can usually resume normal activities immediately, but be sure to mention any persistent headaches or fever, stiff neck, or numbness in the legs, among other concerning symptoms, to your doctor.

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

• Try to keep your upper body elevated about your lower body. When possible, try to remain on your back as much as possible.
• Take plenty of water and avoid drinking alcohol.
• Headaches can be effectively treated with acetaminophen and caffeine beverages since these symptoms resolve independently.
• No bending or vigorous exercise should be performed for 24 hours

How soon can I expect the results of my myelogram?

Your physician will discuss the results of your test when they receive a report from your radiologist. This is usually done within a few days. Then, they will contact you to discuss your results and what to do next.

When should I contact my doctor?

After your myelogram, if you have any of the following, you should contact your doctor immediately

• A temperature higher than 101 degrees Fahrenheit (38.3 degrees Celsius).
• Dizziness, fainting.
• Paresthesia of your legs.
• Discharge or pain at the injection site
• Neck stiff
• Recurring headaches
• Being unable to urinate.
