| Abstract: | Abstract Whiplash injury of the cervical spine is a frequent issue in medical expertises and causes enormous consequential costs for
motor insurance companies. Some authors accuse posttraumatic changes of alar ligaments to be causative of consequential disturbances,
although biomechanical experiments achieve contradictory results and neuropsychiatric studies do not support this thesis.
MRI provides excellent visualization of alar ligaments. However, signal alterations of alar ligaments must be differentiated
from common normal variants. Functional MRI provides no diagnostic yield.
