Which procedure uses X-ray imaging of the spinal cord after injecting contrast into the subarachnoid space?

• A. Myelography
• B. Myelogram
• C. Myography
• D. Electromyography

Answer: (A)

This is myelography. It is the radiographic examination of the spinal canal where contrast is injected into the subarachnoid space to outline the spinal cord and nerve roots on X-ray images. The resulting film or series is called a myelogram. The other tests involve electrical activity of muscles or nerves (myography, electromyography) and do not use intrathecal contrast or X-ray imaging, so they don’t fit the description.
