This article will address ongoing efforts to track cumulative dose estimates of patient radiation exposure that have the potential to transform radiation protection research.
There is no clear consensus on how to use this information clinically. A rational consideration of this question reveals that until the linear no-threshold model is supplanted, cumulative dose estimates are of little clinical relevance and never constitute a logical reason to avoid an imaging evaluation that is otherwise medically indicated.
本文将探讨正在进行的努力，以跟踪患者辐射暴露的累积剂量估计，这有可能改变辐射防护研究。
目前尚无明确共识如何将这些信息用于临床实践。对这个问题进行理性考虑后发现，在线性无阈模型被取代之前，累积剂量估计几乎没有临床意义，并且永远不会构成避免进行医学上有必要的影像学检查的合理理由。
