====== Myelography ======

Myelography is a type of radiographic examination that uses a contrast medium to detect pathology of the spinal cord, including the location of a spinal cord injury, cysts, and tumors. Historically the procedure involved the injection of a radiocontrast agent into the cervical or lumbar spine, followed by several X-ray projections. Today, myelography has largely been replaced by the use of MRI scans, although the technique is still sometimes used under certain circumstances – though now usually in conjunction with CT rather than X-ray projections.

Lutters et al.  commemorated the centenary of myelography, a neuroradiological [[procedure]] that, despite certain disadvantages, significantly contributed to the diagnosis and localization of [[spinal cord lesion]]s during the 20th century. From the start, the use of myelography was characterized by different views regarding the potential dangers associated with the prolonged exposure of a "foreign body" to the [[central nervous system]]. Such differences in attitude resulted in divergent myelography practices; its precise indications, technical performance, and adopted contrast material remaining subject to variability until the procedure were eventually replaced by [[MRI]] at the close of the 20th century

A myelogram may help to find the cause of pain not found by an MRI or CT.

Myelography has been largely replaced by the use of CT and MRI scans.
