Myelography
Barrow Neurological Institute of St. Joseph's Hospital and Medical Center, Phoenix, Arizona
A myelogram is a radiograph that provides detailed information about the inside of the spinal cord. Myelography is used to evaluate a variety of conditions such as spinal tumors, herniated disks, vascular malformations (blood vessel abnormalities), and narrowing of the spinal cord related to degeneration, disease, or trauma to the spinal column.
Mild sedation or general anesthesia is used to keep patients comfortable while dye is injected into the sac around the spinal cord. The injection is completed within 15 minutes, and then spinal radiographs or CT scans are obtained. The dye outlines the shape of the spinal cord and is useful in evaluating areas where the spine is narrowed or compressed.

fluid leak from the subarachnoid to epidural space.
