An x-ray of the spinal cord after injection of air or a radiopaque substance into the subarachnoid space.

A diagnostic method of examining the space around the spinal cord (for example, to detect prolapsed disks) using X-rays and a contrast medium injected by lumbar puncture.

Studies suggest arachnoiditis was present in approximately one percent of patients who had undergone myelography.
With the advent of surface coils and improved imaging techniques, the superiority of MRI over myelography and postmyelography Computed Tomography (CT) in the assessment of intramedullary tumours was established.
This edition has been updated with new advances in radiology; basic current concepts of neuropathology, neurosurgery, and neurology; updated protocols for computed tomography, magnetic resonance imaging, myelography, digital subtraction angiography, and sedation and anxiolysis; and new information on contrast media reactions.
The diagnostic criteria for distal-type CSA included: (1) the presence of cervical spondylosis; (2) the presence of weakness and atrophy in the intrinsic hand and/or finger extension muscles; (3) absence of gait disturbance; (4) absence of bladder or bowel dysfunction; and (5) the presence of a compressive lesion in the anterior horn of the spinal cord, in the nerve root at the intervertebral foramen, or in both sites as seen on the axial and sagittal images of magnetic resonance imaging or computed tomography myelography.
Myelography may be used to identify more accurately subtle changes within the spinal canal, although myelograms are more inherently challenging in avian species because of a narrow cerebromedullary cistern and the lack of contrast flow to the caudal regions of the spinal canal.
Most case reports have used CT and myelography for SEL diagnosis [14, 15].
CT myelography remains an alternative method when MRI is unavailable or cannot be used because of uncontrolled pain, patient size, implanted metallic objects, the inability to lay flat during the exam time, or severe claustrophobia.
CT myelography is used in patients who are intolerant of closed spaces or who cannot undergo MRI9.
