| 中文摘要: |
| 随着CT扫描人次数的持续上升,CT对公众累积辐射剂量的贡献率超过60%。CT扫描中,越靠近人体表面的辐射剂量越高。CT成像新技术的开发和扫描参数的选择,都对表浅辐射敏感器官(如眼晶状体、甲状腺、乳腺)的受照剂量产生影响。如何有效降低表浅辐射敏感器官的辐射剂量是当前研究的热点之一。本文旨在总结表浅敏感器官辐射剂量的影响因素以及剂量降低策略,为临床实践和剂量优化研究提供参考。 |
| 英文摘要: |
| As the number of CT scans continues to rise, the contribution rate of CT to the cumulative radiation dose to the public has exceeded 60%. During CT scanning, a shorter distance to the surface of the human body result in a higher radiation dose. Both the development of new CT imaging techniques and the selection of scanning parameters influence the dosage to superficial radiosensitive organs (e.g., eye lens, thyroid, and mammary glands). Effectively reducing the radiation dose to superficial radiosensitive organs has emerged as a hot research topic. This review aims to summarize the factors influencing the radiation dose to superficial radiosensitive organs and the dose reduction strategies, thus providing a reference for clinical practice and research on dose optimization. |
