  There is reversal of the normal cervical curvature at the vertebral body heights.  The intervertebral disk spaces are otherwise maintained.  There is no prevertebral soft tissue swelling.  The facets are aligned.  The tip of the clivus and occiput appear intact.  On the coronal reconstructed sequence, there is satisfactory alignment of C1 on C2, no evidence of a base of dens fracture.
