After effects of myelography. Ordinary X-ray image of the human spine taken two years after the subject had undergone myelography examination, showing residual oily contrast material (myodil) in the spinal canal (white areas). Myelography is used to examine the neural tissue within the spine through the introduction of a radio-opaque contrast medium (iodized water or oil-based) into the sub-arachnoid space at lumbar puncture. The present material of choice is water-based, due to the frequency of complications from arachnoiditis associated with iodized oil such as myodil. Myelography confined to the lumbar spine is termed radiculography.
