Abstract

This review article discusses technical aspects of computed tomography (CT) imaging of the spine. Patient positioning, and its influence on image quality and movement artefact, is discussed. Particular emphasis is placed on the choice of scan parameters and their relation to image quality and radiation burden to the patient. Strategies to reduce radiation burden and artefact from metal implants are outlined. Data acquisition, processing, image display and steps to reduce artefact are reviewed. CT imaging of the spine is put into context with other imaging modalities for specific clinical indications or problems. This review aims to review underlying principles for image acquisition and to provide a rough guide for clinical problems without being prescriptive. Individual practice will always vary and reflect differences in local experience, technical provisions and clinical requirements.

摘要

这篇综述文章讨论了脊柱计算机断层扫描（CT）成像的技术方面。探讨了患者体位及其对图像质量和运动伪影的影响。特别强调了扫描参数的选择及其与图像质量和患者辐射负担的关系。概述了减少金属植入物辐射负担和伪影的策略。回顾了数据采集、处理、图像显示以及减少伪影的步骤。针对特定临床指征或问题，将脊柱CT成像与其他成像方式进行了对比。本综述旨在回顾图像采集的基本原则，并为临床问题提供一个大致的指导，而非给出具体的规定。个人实践总会有所不同，反映出当地经验、技术条件和临床需求的差异。
