Myelogram

CT Myelogram

Results

A myelogram uses a special dye (contrast material) and X-rays (fluoroscopy) to make pictures of the bones and the fluid-filled space (subarachnoid space) between the bones in your spine (spinal canal).

Myelogram

Normal:	The dye flows evenly through the spinal canal.
	The spinal cord is normal in size, position, and shape. The nerves leaving the spinal cord are normal.
	No narrowing or blockage of the spinal canal is seen.
Abnormal:	The flow of dye is blocked or diverted. This may be due to a ruptured (herniated) disc, spinal stenosis, a nerve injury, an abscess, or a tumor.
	Inflammation of the membrane (arachnoid membrane) that covers the spinal cord is seen.
	One or more nerves leaving the spinal cord are pinched.
