Abstract

As the use of chest CT examination during the COVID-19 outbreak is increased, patient radiation doses are become a concern. So, this survey was conducted to evaluate the patient radiation dose and estimated the cancer risk of chest CT examination during COVID-19 outbreak. From February 2020 to September 2021, 165 Chest CT examination were acquired. For all patients we have examined organ doses and the effective dose using ImpactDose software. The risk of exposure-induced death (REID) values was estimated by using models developed in the BEIR VII (Biological Effects of Ionizing Radiation VII)-Phase 2 report. Study population included 165 patients, 75 male and 90 female, with an average age of 51 years. The mean effective dose in females were greater than in the males (5.42 vs 4.43 mSv, p ˂ 0.0001). The mean REID values in patients undergoing chest CT examination with a 16-MDCT scanner were 232 per million male and 351.3 per million female. The risk of lung cancer was high for both male and female. According to our study, it is proposed that to use low-dose CT chest protocol, as a reliable tool in detecting COVID-19 pneumonia in daily practice, can reduce radiation dose and estimated cancer risk.

COVID-19暴发期间胸部CT检查相关的辐射剂量和暴露致死风险

随着新冠肺炎疫情期间胸部CT检查的使用增加，患者的辐射剂量成为人们关注的问题。因此，本调查旨在评估COVID-19暴发期间患者的辐射剂量，并评估胸部CT检查的癌症风险。2020年2月至2021年9月，165例胸部CT检查。对于所有患者，我们使用ImpactDose软件检查了器官剂量和有效剂量。使用BEIR VII(电离辐射生物效应VII)第2阶段报告中开发的模型估计了暴露诱发死亡(REID)值的风险。研究人群包括165例患者，其中男性75例，女性90例，平均年龄51岁。女性的平均有效剂量大于男性(5.42 vs 4.43 mSv, p小于0.0001)。接受16-MDCT胸部CT检查的患者的平均REID值为男性232 /百万，女性351.3 /百万。男性和女性患肺癌的风险都很高。根据我们的研究，建议在日常实践中使用低剂量CT胸部方案作为检测COVID-19肺炎的可靠工具，可以降低辐射剂量并估计癌症风险。

期刊介绍： Radioprotection publishes articles on all aspects of radiological protection, including non-ionising as well as ionising radiations. Fields of interest range from research, development and theory to operational matters, education and training. The very wide spectrum of its topics includes (theoretical and practical aspects): dosimetry, instrument development, specialized measuring techniques, epidemiology, biological effects (in vivo and in vitro) and risk and environmental impact assessments.
