The introduction of spiral technology to computed tomography (CT) scanners in the late 1980s has revolutionised the field of CT. Spiral CT offers definite practical benefits over conventional scanners and has expanded the role of CT through the development of new scanning techniques. CT scanning now rivals magnetic resonance imaging in many areas of investigation, and for some situations is the clear investigation of choice. This review is aimed at those clinicians who have access to spiral scanning services but wish to have a greater understanding of the technique and its clinical applications. The concept of spiral CT, and the differences between spiral and conventional scanning are discussed. The various clinical applications of the technique are illustrated.
20世纪80年代末螺旋技术引入计算机断层扫描（CT）扫描仪，彻底改变了CT领域。螺旋CT相比传统扫描仪具有明确的实际优势，并通过开发新的扫描技术扩展了CT的作用。如今，CT扫描在许多检查领域可与磁共振成像相媲美，在某些情况下是明确的首选检查方法。本综述针对那些能够使用螺旋扫描服务，但希望更深入了解该技术及其临床应用的临床医生。文中讨论了螺旋CT的概念，以及螺旋扫描与传统扫描的区别，并举例说明了该技术的各种临床应用。
