What is CT Myelography?
Computerised Tomography (CT) Myelography or Myelogram is an imaging procedure in which the rotating beams of X-rays are used after injection of a contrast material to create a real time image of the spinal cord, spinal nerve roots, and the spinal meninges (coverings of the spinal cord) to detect their abnormalities.
Why is CT Myelography done?
- • To assess the structure of the spinal column, spinal nerve roots, and spinal lining or meninges • To diagnose any suspected infections and inflammations of the spinal column • To detect any tumors (abnormal growth) of the spinal column • To detect the lesions or other damage to the spinal column due to trauma • To diagnose herniated discs (discs that bulge and press on nerves and/or the spinal cord) and spinal stenosis (narrowing of the spinal canal) • To diagnose the presence of cysts (benign capsules that may be filled with fluid or solid matter) • To assess any disc abnormalities in patients who cannot undergo MRI
Preparation for CT Myelography
- Pregnant women should inform their doctor (and x-ray technician) as the radiations may affect the fetus. If needed, precautions can be taken to lower the radiation exposure to the fetus.
- Depending on the area to be imaged, you may be asked to wear a hospital gown at the time of the scan.
