Direct Coronal Computed Tomographyof Atlas and Axis Spine

Purpose: To evaluate the usefulness of direct coronal CT technique in demonstrating upper cervical spine lesions and show the advantage superior to X-ray, conventional tomography, conventional CT and MRI examination. Materials and methods: Using Simens ARC CT machine and an removable head-supporting device and direct coronal CT technique. Results: Direct coronal CT provide superior demonstration of skeletal features of upper cervical spine and occipital bone with lower scanning numbers.It's a superior method which meet clinics by large matrix, excellent images and no reconstruction needed.Conclusion:Direct coronal CT is superior to conventional CT and can replace conventional tomography in accessing axis and atlas Spine. Orbital and lens radiation is negligible with direct coronal CT and conventional CT examination.
