CT检查场所新型冠状病毒肺炎防控及辐射安全的研究进展

Infection control status of novel coronavirus pneumonia and radiation safety at CT workplace

CT是辅助诊断新型冠状病毒肺炎的重要影像学工具,因此既需要严格把控CT检查场所及设备的消毒防护及生物安全等卫生管理措施,避免该部位成为潜在的传染源,还需要在保证图像质量及诊断效能的前提下减少CT扫描剂量,较大幅度降低患者受到的辐射危害。根据国内外有关CT场所和设备的新型冠状病毒污染状况的监测研究结果以及CT低剂量扫描诊断新型冠状病毒肺炎的应用现状、应急医院放射卫生防护管理现状,从生物安全的角度提出CT检查场所感染控制及放射卫生防护管理建议,筑牢新冠疫情防控防线。

CT is an important imaging tool for the diagnosis of novel coronavirus pneumonia(COVID-19),therefore,it′s necessary to strictly control the disinfection of CT workplace and equipment and biosafety to avoid the place from becoming a potential infection source and to reduce the risk of infection of patients and radiological staff.It is also necessary to reduce the CT scan dose to minimize the radiation hazards on patients under the premise of ensuring the CT image quality and diagnostic efficiency.Based on the survey that novel coronavirus residues after disinfection at some CT workplace in domestic and overseas and the application of low-dose CT scan in diagnosis of COVID-19,as well as the current situation of radiological protection management in emergency hospital,this paper summarizes and proposes suggestions on infection control and radiological protection for CT workplace to strengthen the defense line of COVID-19 prevention and control.
