| 中文摘要: |
| 近年来,我国放射诊断检查特别是CT检查的频次迅猛增加,已经成为国民人均辐射剂量的最大人工辐射来源,并有可能超过天然辐射源的贡献。临床诊疗活动中,患者和受检者短时间内可能进行多项目、多频次的放射诊断成像,所接受的累积辐射剂量较高,甚至一天检查的剂量贡献超过50或100 mSv,从而对其健康产生潜在风险。因此,有必要对放射诊断辐射剂量信息进行统计分析与控制管理,以尽可能降低过高剂量及其辐射危险的发生概率。本文对放射诊断辐射风险的国际认识、我国放射诊断设备和检查频次、放射诊断辐射剂量及其管理现状进行阐述,并就辐射剂量的管理提出应对策略,为进一步推进临床实践中的辐射防护提供参考。 |
| 英文摘要: |
| In recent years, the diagnostic radiology, especially CT scanning, has a rapidly increased frequency in our country, becoming the largest artificial radiation source to the average individual doses to the population. In clinical diagnosis and treatment activities, the examined patients and individuals may undergo multiple procedures and multiple frequencies of medical imaging in a short period of time and receive high cumulative radiation doses even exceeding 50 or 100 mSv in a single day, posing a potential risk to their health. Therefore, it is necessary to carry out statistical analysis and management of diagnostic radiation dose information to minimize the probability of excessive dose and associated radiation risk. In this paper, the international cognition of radiation risks in diagnostic radiology, diagnostic equipment and medical imaging frequency, radiation dose and its management status are described. Four countermeasures for radiation dose management are put forward to provide reference for further improving radiation protection in clinical practice. |
