Neck bones and spinal cord. Coloured coronal computed tomography (CT) scan of the neck bones and spinal cord of a 43-year-old man. This scan uses a contrast medium to highlight the spinal cord and the nerves branching off it, in a technique known as myelography. The scan shows the normal anatomy of the cervical (neck) region of the spinal cord, the spinal nerve roots, and the anatomy of the cervical vertebrae (spinal bones).
