Abstract

Technologic advances in CT have generated a dramatic increase in the number of CT studies, with a resultant increase in the radiation dose related to CT scanning. Such increase in radiation dose is becoming a concern for the radiology community, especially with increasing public awareness of the dose burden related to examinations. To cope with the increase in CT-related radiation exposure, it is becoming necessary to optimize CT imaging protocols and apply radiation dose reduction techniques to ensure the best imaging with the lowest radiation dose.

摘要

CT 技术的进步使得 CT 研究数量大幅增加，与之相关的 CT 扫描辐射剂量也随之增加。这种辐射剂量的增加引起了放射学界的关注，尤其是公众对检查相关辐射负担的认识不断提高。为了应对与 CT 相关的辐射暴露增加，有必要优化 CT 成像方案并应用辐射剂量降低技术，以确保以最低辐射剂量获得最佳成像效果。
