The outbreak of coronavirus disease 2019 (COVID-19) is a huge threat to global public health because it develops rapidly. There is no specific treatment so far. Chest imaging examination is an important auxiliary examination method in diagnosis of COVID-19. To further standardize the imaging examination and diagnosis of COVID-19, Hunan Society of Radiology together with Imaging Technology Professional Committee of Hunan Medical Association reach an expert consensus document on imaging examination, diagnosis, and control and prevention of nosocomial infection for COVID-19. This document summarizes the epidemiological characteristics, clinical features, imaging examination procedure, imaging findings, CT staging, the value of imaging examination, and the methods for control and prevention of nosocomial infection for COVID-19 during imaging examination. Furthermore, it extends the clinical characteristics and imaging manifestations of COVID-19 in children.
自新型冠状病毒疫情暴发以来，该病毒传播迅速、传染性强且尚无特异性治疗方法，对全球公共卫生形成了巨大威胁。胸部影像学检查是新型冠状病毒肺炎(coronavirus disease 2019，COVID-19)诊疗过程中的重要诊断方法。为进一步规范COVID-19的影像学检查与诊断工作，湖南省医学会放射学专业委员会和湖南省医学会影像技术专业委员会联合制定了湖南省COVID-19影像学检查、诊断及医院内感染预防与控制专家共识。本共识阐述了COVID-19的流行病学特征、临床特征、影像学检查流程、影像学表现和CT分期、影像学检查的价值，以及影像学检查医院内感染预防与控制方法，同时总结了儿童COVID-19的临床特点和影像学表现。.
