毕节地区新型冠状病毒肺炎胸部CT影像学特征

Chest CT imaging features of patients with 2019-nCov-pneumonia in Bijie

目的分析毕节地区新型冠状病毒(2019-nCoV)肺炎(novel coronavirus pneumonia,NCP)胸部CT影像学表现,探讨对NCP的临床诊断的价值。方法回顾性分析毕节市第三人民医院2020年1月14日至2月18日收治的13例NCP患者的流行病学特征及胸部CT影像学特征。结果13例患者中2例为长期居住在武汉来毕;1例由从上海到湖北宜昌逗留3天返毕;1例直接与武汉当地人接触;3例为与确诊病人的密切接触者;5例是聚集性发病,均与从浙江省台州市返毕确诊病人密切接触;1例无流行病学史。胸部CT影像学以双肺或一侧肺散在斑片状、磨玻璃状高密度影,密度不均,边界不清,肺野外带显著为特征。重型患者短期内肺部CT影像学变化明显。结论确诊NCP普通型患者胸部CT影像学大多以典型表现为特征;重型NCP患者短时间内可出现实变及肺纤维化。

Objective To analyze the novel coronavirus(2019-nCoV)novel coronavirus pneumonia(NCP)chest CT imaging findings in Bijie area,and to explore the clinical diagnostic value of NCP.Methods The epidemiological characteristics and chest CT features of 13 NCP patients admitted to The Third People's Hospital of Bijie from January 14 to February 18,2020 were analyzed retrospectively.Results Among the 13 patients,2 lived in Wuhan for a long time,1 stayed for 3 days from Shanghai to Yichang,Hubei,and returned home;1 directly contacted with the local people in Wuhan;3 closely contacted with the confirmed patients;5 were clustered diseases,all closely contacted with the confirmed patients returning from Taizhou,Zhejiang province;1 had no epidemiological history.CT imaging of the chest is characterized by patchy,ground glass high-density shadows scattered in two or one side of the lung,with uneven density,unclear boundary and significant lung field zone.Conclusion Most of the chest CT images of the patients with NCP were characterized by typical manifestations,while consolidation and pulmonary fibrosis were found in the patients with severe NCP in a short period of time.
