摘要
目的回顾性分析新型冠状病毒肺炎(Coronavirus Disease 2019,COVID-19)患者CT扫描的临床应用和CT低剂量扫描的辐射控制优势。方法记录并分析98例就诊于发热门诊和急诊内科CT扫描阳性患者的信息,分析其年龄分布,多次检查次数以及重复检查间隔时间;分析比较不同CT扫描参数控制下的辐射剂量,并揭示低剂量CT扫描保护效应。结果 COVID-19流行的近期,进行CT扫描的发热患者,年轻化占比偏多,多次重复CT扫描常见且其时间间隔短。COVID-19临床诊断病例患者CT低剂量扫描(Low Dose Sn100 kV),比较两种参数的常规胸部CT平扫(Thorax 110 kV,Thorax 100 kV),其辐射剂量明显偏低,且具显著性差异(P<0.001)。结论 CT扫描技术是COVID-19流行期间快速、高效辅助诊断和评估治疗的检查技术,更是COVID-19临床诊断病例的黄金标准。CT低剂量扫描技术可显著性降低患者的受辐射剂量,在COVID-19肆虐的特殊时期,应用于COVID-19患者检查的远期有利效应不容忽视,一定程度保护年轻育龄患者以及需频繁复查的患者。
Objective To analyze the CT images of coronavirus disease 2019(COVID-19)patients and the radiation control advantages in low dose CT scanning.Methods The age distribution,the times of multiple examinations and the interval of repeated imaging on 98 patients’CT scanning information in fever clinic and emergency department were recorded and analyzed.The radiation dose under different CT scanning parameters was compared,and the protective effect of low dose CT scanning was revealed.Results The proportion of fever patients who undergone CT scan was younger in the near future that COVID-19 was popular.Repeated CT scan was common and the time interval was so short.Low dose CT scan(Low dose Sn100 kV)of COVID-19 patients was significantly lower than that of conventional chest CT scan(Thorax 110 kV,Thorax 100 kV),and the results had significant difference(P<0.001).Conclusion CT scanning technology is a rapid and efficient examination technology for the diagnosis and treatment of COVID-19 during the epidemic period,and it is also the gold standard for the clinical diagnosis of COVID-19.CT low-dose scanning technology can significantly reduce the radiation dose of patients.In the special period of COVID-19,the long-term beneficial effect applied to COVID-19 patients cannot be ignored using low-dose CT scanning to protect young patients of childbearing age and patients who need repeated examinations.
