**4. Kinematic imaging of the craniocervical junction**

The complex nature of the structure and function of the craniocervical junction makes it especially vulnerable to injury and deformation. Forces acting upon the head and cervical spine as occurs in head/neck trauma, may occur in complex patterns [40]. Accordingly, it is important to ensure that complex injuries are properly evaluated and are not overlooked as complex injury scenarios are plausible when trauma occurs to the craniocervical junction [41].
