Answer

Answer

Myelography is useful in elucidating nerve root pathology, particularly in patients with previous lumbar spinal surgery or with a metal fixation device in place. CT myelography provides the accurate visual definition to elucidate neural compression or arachnoiditis when patients have undergone several spinal operations and when surgery is being considered for the treatment of foraminal and spinal canal stenosis.
