Where is the contrast medium injected for myelography?
This test is also called a myelogram.Inject contrast dye into the spine before the program. The contrast agent appears on the X-ray screen, allowing radiologists to see the spinal cord, subarachnoid space, and other nearby structures more clearly than with standard spine X-rays.
Where is Dye Injection Myelography?
The dye (contrast) used for myelography appears white on X-rays and allows doctors to see the spinal cord, exiting nerves, and root canals in detail. The doctor inserts a hollow needle through your skin into the spinal canal.Dye is injected into the space around the spinal cord and nerve roots (figure 1).
How much contrast is injected for myelography?
Iodine-containing contrast media, usually about 10 ml, which is then injected into the fluid surrounding the spinal cord. If you have lower back problems, when injecting contrast, the table may be tilted slightly so that your feet are slightly lower than your head to allow the contrast to flow down your lower back.
What is the route of administration of contrast agents in myelography?
Myelography needs Plain radiographs of the spine after intrathecal instillation of iodinated contrast at the posterior C1-C2 level of the spinal cord by lumbar puncture or cervical puncture. Use only water-soluble non-ionic contrast media.
Where is the needle for a lumbar puncture placed during myelography?
A lumbar puncture is done by inserting a hollow needle The subarachnoid space in the lumbar region of the spine (lower back). The subarachnoid space is the tube in the spine that carries cerebrospinal fluid (CSF) between the brain and spinal cord.

Can myelography cause paralysis?
In rare cases, inflammation of the spinal cord, weakness, numbness, paralysis, or loss of control of the bowel or bladder may occur. Also in rare cases, the dye may cause a blockage of the spinal canal. If this happens, surgery is usually required.
What is the difference between a CT scan and a myelogram?
Myelography involves injecting an opaque dye (a dye that absorbs X-rays) into the sac around the nerve root to light up the nerve root. CT scans then show how the bone affects the nerve roots.

How is CT myelography performed?
In the first part of the CT myelography, Injecting contrast into your spinal canal under X-ray guidance. Contrast media is used to illuminate your spinal canal, spinal cord, and nerve roots during imaging. After the injection, an X-ray will be taken using a fluoroscopy machine.
Is surgery considered for myelography?
Because this is an invasive procedure that requires injection of contrast through a spinal needle, there are some risks, including: Spinal fluid infection (meningitis).
Are there alternatives to myelography?
NMR Provides the same information as a myelogram without injecting a contrast agent. CT myelography has certain advantages, including details of bony structures.
