Abstract
THE PURPOSE OF THIS STUDY was to assess the accuracy of three magnetic resonance imaging (MRI) techniques (standard sagittal, oblique sagittal reformatted, and direct oblique) in the morphometric evaluation of the clinically relevant vertical dimension of the cervical intervertebral foramina (IVFs). This was done by means of a blinded comparison of vernier caliper measurements made directly from 11 cadaveric cervical IVFs versus measurements made from MRI scans of the same IVFs. The facilities used were the gross anatomy laboratory and MRI scanning facilities of a chiropractic college. The intraobserver reliability, interobserver reliability, and accuracy of the measurements of three observers were calculated for the imaging modalities. Only three of the 11 IVFs could be adequately evaluated using the standard sagittal MRI protocol. Measurements made from the other two MRI techniques showed high reliability and accuracy. The direct oblique MRI protocol developed for this study required fewer steps than the oblique sagittal reformatted technique, used a T1-weighted scan that produced very clear images, and still allowed the cervical IVFs to be viewed in an anterior-inferior oblique plane. It was concluded that direct oblique imaging is superior to standard sagittal (parasagittal) and oblique sagittal reformatted MRI in the morphometric evaluation of the cervical IVFs. The results of this work should aid clinicians and researchers in their understanding of the strengths and weaknesses of MRI in the evaluation of the cervical IVFs, thus helping to more accurately evaluate patients with pain arising from foraminal stenosis in the cervical region.
