Dynamic MRI and Quantitative MR CSF Flow Studies in Craniovertebral Junction Anomalies

In this study, subjects will have a dynamic cervical magnetic resonance imaging (MRI) of the craniovertebral junction (CVJ) coupled with CSF flow studies. The studies will assess changes in CSF flow velocities that are associated with with changing position of the neck at the CVJ and aqueduct of Sylvius. Eligible patients include those with Chiari 1 malformations and similar malformations to the CVJ. This malformation lead to inherent instability in this region and symptoms such as headaches, dizziness, neck pain and other neurological problems. This study will determine if there is any correlation of these MRI findings to clinical outcome.
