摘要 维持CT扫描过程中的放射剂量在一个合理的低范围,从而减少致癌因素,是目前最重要和最具挑战性的课题。本文重点介绍了最新有效降低放射剂量的技术,以及讨论日常临床应用中有效低放射剂量的管理策略。 To keep radiation dose as low as reasonably low remains the most important and challenging strategy for the potential risk of cancer induction from CT scan. This paper reviews the latest techniques to effectively reduce the radiation dose and discuss the low dose management strategy for routine clinical applications.
