Functional cervical MRI within the scope of XXXX : presentation of a new motion device for the cervical spine.

PURPOSE: Frequently following a @entity7125 of the cervical spine, @entity1 suffer from persistent @entity158 symptoms. The MRI will in some of these cases show changes consistent with disk pathology or @entity612 , although in most instances the imaging studies will offer no adequate explanation for the described symptoms. The goal of our research was to develop and test a new MRI compatible device that will allow functional imaging of the cervical spine. METHODS: A total of 30 @entity1 with @entity7125 were evaluated during the first 6 weeks following trauma with the functional MRI. The examination was carried out with a T2-weighted turbo spin-echo sequence utilizing a new apparatus consisting of an inflatable air bag contained in a Plexiglas housing. Thanks to a valve placed outside of the examination room, it was possible to individually regulate the amount of air used to fill the pillow, thereby obtaining a full range of motion between flexion and extension. RESULTS: In 25 cases no pathology was found during this examination. Two @entity1 presented with scarring of the alar ligaments, indicative of a traumatic lesion. In two other instances the images in reclination revealed a bulging disk, while in one case a widening of the disk space was found as a sign for a rupture of the anterior longitudinal ligament. CONCLUSION: Our study was able to demonstrate the applicability of the new functional testing device, which permits a standardized, continuous and dynamic evaluation of the cervical spine in a closed MRI.
