快速的技术发展，以及越来越多的应用程序取代了不太准确或更具侵入性的诊断测试，导致人体CT成像自1975年推出以来在医疗实践中的应用急剧增加。我们在这里的目的是讨论与CT中使用的电离辐射相关的小风险的医学依据，并为具体的实践决策提供观点，从而最大限度地提高患者的总体效益。此外，我们回顾了现有的剂量管理和优化技术。
Rapid technical developments, and an expanding list of applications that have supplanted less accurate or more invasive diagnostic tests, have led to a dramatic increase in the use of body CT imaging in medical practice since its introduction in 1975. Our purpose here is to discuss medical justification of the small risk associated with the ionizing radiation used in CT and to provide perspectives on practice-specific decisions that can maximize overall patient benefit. In addition, we review available dose management and optimization technique.
