环枢椎冠状CT扫描方法及临床应用价值
Direct Coronal Computed Tomographyof Atlas and Axis Spine
-
摘要: 环枢椎冠状CT扫描因其受到人体结构及设备的制约,技术难度较大,故很少有单位开展此项检查。我院影像科与北医三院脊柱外科协作,为了临床的需要,解决环枢椎外伤及术前术后的诊断问题,我们对环枢椎的直接冠状CT扫描进行了尝试。结果令人满意,达到了临床的诊断要求。Abstract: 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.
