A myelogram uses X-rays (fluoroscopy) and a special dye called contrast material to make pictures of bones
and nerves of the spine (spinal canal).
The spinal canal contains the spinal
cord and nerve roots surrounded by a fluid-filled space called the subarachnoid
space. For a myelogram, the dye (which contains iodine) is put
into the subarachnoid space. X-ray pictures are taken as the dye moves into
different areas of the subarachnoid space.
A myelogram can be used to find:
A blockage in the spinal canal that may be
caused by a tumor or by a spinal disc that has ruptured
Inflammation of the membrane (arachnoid membrane) that
covers the brain and spinal cord.
Problems of the blood supply to
the spinal cord.
Problems of the spinal cord and the nerves that
branch off from the spinal cord.
