The spinal canal holds the spinal cord, spinal nerve roots, and the subarachnoid space.
During the test, a dye is put into the subarachnoid space with a thin needle. The dye moves through the space so the nerve roots and spinal cord can be seen more clearly. Pictures may be taken before and after the dye is used. To get more information from the test, a CT scan is often done after the X-rays, while the dye is still in your body.Good luck big sexy!
