摘　　要：新型冠状病毒感染(coronavirus disease 2019,COVID-19)是一种新发、突发以呼吸系统症状为主要表现的传染病。目前在全球范围内广泛流行,感染患者已高达数亿人,严重威胁了全球公共卫生的安全。该病以引起呼吸道症状为主,肺组织的损伤是患者主要的临床表现。胸部CT在呼吸系统疾病的诊疗中具有显著的优势。它不仅能在早期较金标准-实时逆转录聚合酶链反应检测更敏感地识别肺部感染,还可用于评估疾病的严重程度、监测疾病的进程、观察患者肺纤维化的转归等,进而指导临床的决策。所以,在疫情防控工作中,胸部CT具有重要的作用。笔者结合国内、外最新研究总结、归纳该病典型的CT影像特征、不同临床分型、不同时期及特殊人群的CT影像学的研究进展,探讨胸部CT在COVID-19诊疗工作中的价值。As a new emergent infectious disease,coronavirus disease 2019(COVID-19)is currently prevalent worldwide,infecting hundreds of millions of people,seriously threatening global public health security.The disease mainly causes respiratory symptoms,and lung injury is the main clinical manifestation of COVID-19 patients.Chest CT has unique advantages in displaying signs of lung diseases.It can not only identify early pulmonary infection more sensitively than the gold standard real-time reverse transcription polymerase chain reaction,but also evaluate the severity of the disease,monitor the disease process,and guide clinical decision-making.It can also observe the prognosis of patients with pulmonary fibrosis.Therefore,chest CT has been playing a vital role in epidemic prevention and control.Combined with the latest research progress at home and abroad,this paper summarizes the main CT imaging characteristics of the disease,the progress of chest CT imaging research in different clinical types and different stages of the disease,and discusses the value of chest CT examination in COVID-19 pneumonia.
