CT Myelography
Understanding CT Myelography
What is CT Myelography?
Computed Tomography (CT) Myelography is an imaging procedure to create a real-time image of the spinal cord, spinal nerve roots, and the spinal meninges to detect their abnormalities. During the test, contrast dye is injected into the spinal canal. Contrast dye is a substance that makes specific organs, blood vessels, and tissue shows up more clearly.
This test is needed in case of symptoms of spinal cord disorders like pain in the back, tingling sensation, weakness, and trouble walking.
This test is prescribed by the doctor to assess the structure of the spinal column, spinal nerve roots, and spinal lining, to diagnose any suspected infections and inflammations of the spinal column, and to detect any tumors (abnormal growth) of the spinal column.
CT exams generally use a small amount of radiation and are therefore considered relatively safer as compared to X-rays.
What is CT Myelography used for?
- • 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
