Why get a CT/myelogram instead of MRI?

Non-Surgical Frequently Asked Questions
Plain CT scans do not provide spine surgeons with enough information to adequately plan for surgical procedures. The CT/myelogram provides information about the bony architecture of the spine and additional information about the spinal cord and nerve roots, and their location within the spinal canal. In patients with pressure on nerve roots from bone spurs, the CT scan/myelogram test can help define the exact location and severity of the nerve root compression.
