=== Dynamic imaging === Dynamic components can be added to many common imaging techniques to see how structure and function change in different positions. For example, a cervical MRI can be take in a neutral position, and compared to images taken of the neck in flexion and extension. This can aid in the diagnosis of [[Chiari malformation]], [[Cerebellar tonsillar herniation]], [[Craniocervical instability]], and positional cord compression due to [[Cervical spinal stenosis]]. A cervical CT scan can be taken of the neck in neutral as compared to left and right positions to aid in the diagnosis of [[Atlantoaxial instability]]. Other types of imaging seek to observe the dynamic flow of fluid in the nervous system. For example, a [[cine MRI]] is used to observe [[cerebrospinal fluid]] flow, which can be obstructed in some conditions, such as [[Chiari malformation|Chiari]].
