From all the available radiodiagnostic procedures for diagnosing spinal disorders (conventional tomography, myelography, CT), high-resolution, thin-slice computer tomography presents the highest radiation exposure as represented by the somatic dose index. It allows, however, the retrospective computer reformatting of axial slices into secondary slices of any projection desired. To obtain this extra information with conventional tomography would require further exposures in the desired projections and/or thinner slices. But there is a great amount of important diagnostic information that plays a decisive role in the choice of the form of therapy and the preoperative planning of surgical which cannot be obtained by conventional radiological procedures.
在所有用于诊断脊柱疾病的放射诊断程序中(传统体层摄影、脊髓造影、CT),高分辨率薄层计算机断层扫描的体部剂量指数所代表的辐射暴露最高。然而,它允许将轴向切片进行回顾性计算机重新格式化,以生成任何所需投影的二次切片。要通过传统体层摄影获得这些额外信息,就需要在所需投影方向和/或更薄的切片上进行进一步的曝光。但是,有大量重要的诊断信息在治疗方式的选择和手术的术前规划中起着决定性作用,而这些信息是传统放射学程序无法获得的。
