Myelography is a diagnostic procedure that is used to observe the spinal cord and nerves with the help of a contrast material. It is typically done to evaluate spinal cord stenosis, which is the narrowing of the spaces within your spine that can put pressure on the spinal cord or nerves. This procedure involves the use of a long, thin needle to inject a contrast material into the spinal canal, which acts as an X-ray dye. The dye then shows up on X-ray images, allowing your healthcare provider to identify any abnormalities or issues.
During myelography, a radiologist or a specially trained healthcare provider inserts a needle into your lower back. They then inject the contrast material into your spinal canal, which covers and outlines the spinal cord and nerve roots. This allows the healthcare provider to see any inflammation, tumors, herniated disks, or other conditions that may be causing your symptoms. The X-ray images taken during myelography can help determine the cause of symptoms such as pain, numbness, or weakness in certain parts of your body.
Myelography is a relatively safe procedure, but there are some risks involved. The most common side effect is a headache, which can occur after the procedure. This headache is typically caused by leakage of spinal fluid from the puncture site. It usually goes away within a few days, but if it persists or worsens, you should contact your healthcare provider. Other rare complications include infection, bleeding, or an allergic reaction to the contrast material.
In conclusion, myelography is a valuable diagnostic tool for evaluating spinal cord stenosis and other conditions affecting the spinal cord and nerves. It provides detailed images that can help your healthcare provider identify and diagnose the cause of your symptoms. If you’ve been experiencing pain, numbness, or weakness in certain parts of your body, myelography may be recommended to help determine the underlying cause. While there are some risks involved, the benefits of this procedure often outweigh the potential complications.
What is it used for
Myelography is a diagnostic imaging test that is used to detect inflammation, stenosis, or other abnormalities in the spinal cord and disks. It is also used to evaluate the cause of a persistent headache.
During the procedure, a contrast dye is injected into the spinal canal using a fine needle. This dye helps to highlight the spinal cord and disks so that they can be better visualized on X-ray or CT scan images. By identifying any abnormalities with this procedure, doctors can determine the need for further treatment or intervention.
Administrative spending is particularly problematic in United States hospitals, where it makes up about 25% of total hospital spending and accounts for hundreds of billions of dollars in healthcare spending annually, The Commonwealth Fund The percentage of total hospital spending devoted to administration is highest in for-profit hospitals, followed by nonprofit hospitals, teaching hospitals, and finally public hospitals. Outdated reimbursement and reporting methods are a big part of the administrative cost, says Salvo-Wendt. “Reimbursing in bundled payments instead of itemizing each service or component would produce instant savings of administrative costs.”
Myelography is particularly useful in cases where an MRI or CT scan cannot provide enough information, such as when a patient has metal implants or is claustrophobic. Additionally, it can help to identify conditions such as spinal stenosis, herniated disks, or tumors that may be causing symptoms such as pain or weakness.
Although myelography carries some risks, such as the potential for an allergic reaction to the contrast dye or the need for exposure to radiation, it is generally considered to be a safe and effective imaging tool. If you’ve been experiencing persistent headaches or have been recommended for myelography, talk to your doctor to determine if this procedure is right for you.
Why do I need myelography
Myelography is a diagnostic procedure that involves injecting a contrast dye into the spinal canal to visualize the spinal cord and nerves. It is usually done when an MRI or CT scan cannot provide sufficient information.
This procedure is necessary for a variety of reasons. One of the main reasons is to detect inflammation or infection in the spinal cord or surrounding tissues. Inflammation can be caused by conditions such as meningitis or multiple sclerosis.
Myelography can also help identify the causes of nerve root compression or stenosis, which can result in pain, weakness, and difficulty walking. This procedure allows doctors to see if there is any narrowing of the spinal canal or compression of the nerves.
If you have persistent and unexplained headache, myelography may be recommended to rule out the possibility of cerebrospinal fluid leak. This can occur due to a tear in the covering of the spinal cord or a defect in the bones that protect the spinal canal.
Myelography is particularly useful when examining the intervertebral disks in the spine. It can help determine if there are any ruptured or herniated disks that are pressing on the spinal cord or nerves.
The procedure involves inserting a thin needle into the spinal canal, usually in the lower back. The contrast dye is then injected, and X-ray images or CT scans are taken to visualize the flow of the dye. The radiation from these imaging techniques helps create detailed images of the spinal cord and nerves.
Overall, myelography is a valuable tool in diagnosing and evaluating conditions of the spinal cord and nerves. By providing clear images of the affected areas, it helps guide further treatment decisions and improves patient outcomes.
What happens during myelography
During myelography, a special type of X-ray called fluoroscopy is used to examine the spinal cord and the spaces around it. This procedure helps doctors diagnose conditions affecting the spine, such as herniated disks, spinal stenosis, or spinal cord compression.
The procedure begins with the patient lying on their stomach or side on an X-ray table. The skin over the lower back is cleaned and numbed with a local anesthetic. A thin needle is then inserted into the spinal canal. This needle is used to inject a contrast dye into the subarachnoid space, which surrounds the spinal cord and nerves.
Once the dye is injected, X-rays are taken in real-time to visualize the flow of the dye. This allows the doctor to see any abnormalities, such as compression or blockages, in the spinal cord or nerve roots. The patient may be asked to change positions or hold their breath to help get the best images.
Some patients may experience a mild headache after the procedure, which can be relieved with over-the-counter pain medications. It is important to stay well-hydrated after myelography to help flush the contrast dye out of the body.
What causes the headache?
The headache is a common side effect of myelography and is caused by a small amount of cerebrospinal fluid leaking from the puncture site. This fluid loss can lead to a drop in pressure around the brain, resulting in a headache.
Do I need to do anything to prepare for myelography?
Prior to the procedure, your doctor will provide instructions on any necessary preparations. This may include fasting for a certain period of time or temporarily stopping certain medications. It is important to follow these instructions to ensure a successful and safe myelography.

Following these preparation instructions will help ensure a successful and safe myelography procedure. If you have any questions or concerns, make sure to discuss them with your healthcare provider.
Are there any risks to the test
Myelography is generally a safe procedure, but there are some risks involved.
Inflammation
There is a risk of inflammation in the area where the needle was inserted. This can cause pain or discomfort. If you experience any unusual swelling, redness, or warmth at the injection site, you should contact your healthcare provider.
Disks and Spinal Cord Injury
In rare cases, myelography may cause injury to the spinal cord or the disks in the spine. This can result in neurological symptoms such as weakness, numbness, or paralysis. If you notice any of these symptoms after the test, you should seek immediate medical attention.
Radiation Exposure
Myelography involves the use of X-rays, which exposes you to a small amount of radiation. The risk of developing radiation-related side effects is low, but it increases with repeated exposure. If you are pregnant or suspect that you may be, you should discuss the risks and benefits of the procedure with your healthcare provider.
Other possible risks include headache, allergic reactions to the contrast dye, and the rare occurrence of infection. However, these risks are very low.
It is important to remember that the benefits of myelography usually outweigh the risks. If your healthcare provider determines that you need this test, it is because they believe it will provide valuable information to help diagnose or treat your condition.
If you have any concerns or questions about the risks associated with myelography, be sure to discuss them with your healthcare provider before the procedure.
What do the results mean
After you’ve undergone myelography, the results will provide valuable information about the condition of your spine. The procedure involves the use of a contrast dye and radiation to obtain detailed images of the spinal cord and its surrounding structures.
If your myelogram shows stenosis, it indicates that there is narrowing of the spinal canal, causing compression on the nerves. This can lead to symptoms such as pain, weakness, and numbness in the affected areas.
The images produced by myelography can also reveal any abnormalities or changes in the discs of your spine. It can detect herniated or bulging discs, which can put pressure on the spinal cord or nerve roots.
In addition, myelography can detect inflammation in the spinal cord or its coverings. This can be indicative of conditions such as meningitis or arachnoiditis. Inflammation can cause symptoms like headache, stiffness, and pain.
If abnormalities are found during your myelography, further tests or treatments may be necessary to determine the underlying causes. Your doctor will discuss these results with you and develop an appropriate plan of action to address your specific needs.
Is there anything else I need to know about myelography
Myelography is a diagnostic imaging test that can help detect spinal cord problems such as stenosis, inflammation, or disk herniation. It involves injecting a contrast dye into the spinal canal using a needle, which allows the radiologist to obtain detailed images of the spinal cord and surrounding structures.
During the procedure, you may experience a temporary headache due to the injection. This can usually be managed with over-the-counter pain relievers. If you experience severe or persistent headache, you should contact your healthcare provider.
It’s important to inform your healthcare provider about any allergies you have, especially to iodine or shellfish, as the contrast dye used in myelography may contain these substances. Additionally, let your healthcare provider know if you’ve had any previous reactions to contrast dye or if you’re pregnant, as myelography involves exposure to radiation.
After the procedure, you may be required to remain lying down for a period of time to allow the contrast dye to evenly disperse. Your healthcare provider will provide specific instructions on when you can resume normal activities.
While myelography can provide valuable information about the spinal cord, it may not be suitable for everyone. If you have certain medical conditions or are taking certain medications, your healthcare provider may recommend an alternative diagnostic test. It’s important to discuss any concerns or questions you have with your healthcare provider before undergoing myelography.
