What is normal myelogram?
Myelography uses a real-time form of x-ray called fluoroscopy and an injection of contrast material to evaluate the spinal cord, nerve roots and spinal lining (meninges). It is particularly useful for assessing the spine following surgery and for assessing disc abnormalities in patients who cannot undergo MRI.
What is a myelogram used to diagnose?
A myelogram may be done to assess the spinal cord, subarachnoid space, or other structures for changes or abnormalities. It may be used when another type of exam, such as a standard X-ray, does not give clear answers about the cause of back or spine problems.
Can a myelogram detect MS?
This is then analysed in the laboratory to see if characteristic features of MS are present. A myelogram is an x-ray of the spinal cord taken after dye has been injected into it. Any obstructions to the flow of dye along the spinal cord may help diagnose other causes for the symptoms other than MS.
Will a myelogram show nerve damage?
A myelogram is able to show your spinal cord, spinal nerves, nerve roots, and bones in the spine by injecting contrast into your spinal fluid. As a result, it will also reveal whether anything is pressing against your spinal cord or nerves.
What is the difference between a CT scan and a myelogram?
A myelogram consists of injecting a radiographically opaque dye (dye that is picked up by x-ray) into the sac around the nerve roots, which in turn lights up the nerve roots. The CT scan follows and shows how the bone is affecting the nerve roots.
What is the most common clinical indication for a myelogram?
What are the generally accepted indications for a myelogram?
- In patients who require imaging as a result of a clinical diagnosis of nerve root, thecal sac or spinal cord compression from disc, tumour or spinal stenosis, where MRI is:
- In patients with clinical symptoms and signs of a CSF leak.
Why is a myelogram so painful?
How does it feel? You will feel a quick sting from a small needle that has medicine to numb the skin on your back. You will also feel some pressure as the long, thin spinal needle is put into your spinal canal. You may feel a quick, sharp pain down your buttock or leg when the needle is moved in your spine.
What is a a myelogram?
A myelogram is a diagnostic imaging test generally done by a radiologist. It uses a contrast dye and X-rays or computed tomography (CT) to look for problems in the spinal canal. Problems can develop in the spinal cord, nerve roots, and other tissues. This test is also called myelography. The contrast dye is injected…
What happens after a myelogram?
What happens after a myelogram? You need to sit or lay down for several hours after the procedure to reduce your risk of developing a CSF (cerebral spinal fluid) leak. Most patients are asked to lie down for two hours after the procedure.
How to prepare for a myelogram procedure?

What is the difference between myelography and a CT scan?
In such cases, myelography and/or a CT scan, in lieu of MRI, is performed to better define abnormalities. Myelography is most commonly used to detect abnormalities affecting the spinal cord, the spinal canal, the spinal nerve roots and the blood vessels that supply the spinal cord, including:
