摘　　要：目的:探讨新型冠状病毒肺炎(COVID-19)患者胸部CT表现及其动态变化规律。方法:收集经病毒核酸检测确诊的5例COVID-19患者完整胸部CT资料,所有患者住院期间持续随访胸部CT,每次胸部CT间隔2~7 d不等。重点分析每次CT图像上病灶的位置、数目、分布、形态、密度与随时间变化的特点。结果:5例患者中男性3例,女性2例,年龄3~60岁。首次CT检查:1例(1/5)阴性,1例(1/5)仅左肺上叶单发,3例(3/5)双肺多发。病变位于肺外带3例(3/5),肺外带及中央1例(1/5)。磨玻璃影2例(2/5),磨玻璃影与网格状影1例(1/5),磨玻璃与斑片状实变影1例(1/5),伴随血管增粗4例(4/5),支气管充气征1例(1/5)。动态变化(病变演变)过程中磨玻璃影逐渐减少,实变影先增多后减少,纤维索条逐渐增多。入院第6~9天病变不同程度进展,形态多样。10~14 d后病变逐渐吸收。结论:COVID-19患者CT表现有一定的特征,动态变化有一定规律,掌握这些特点及规律对该病早诊断、早隔离、早治疗及疗效评价具有重要价值。Objective:To investigate the CT findings and dynamic changes of patients with corona virus disease 2019(COVID-19).Methods:The complete chest CT data of 5 patients with COVID-19 confirmed by viral nucleic acid test were retrospectively analyzed.All patients were followed up with chest CT during hospitalization,with interval of 2-7 days for each chest CT.The characteristics of the location,number,distribution,morphology,density and time variation of the lesions on each CT image were analyzed.Results:There were 3 males and 2 females aged from 3 to 60 years old.The first CT examination showed that 1 case(1/5)was negative,1 case(1/5)had single lesion in the left superior lobe,and 3 cases(3/5)had multiple lesions in double lungs.The lesions were located in the extraneous zone of the lung in 3 cases(3/5),and the extraneous zone and central zone of the lung in 1 case(1/5).There were 2 cases of ground glass shadow(2/5),1 case of ground glass shadow and mesh shadow(1/5),1 case of ground glass shadow and patchy consolidation shadow(1/5),4 cases of blood vessel thickening(4/5),and 1 case of bronchial inflation sign(1/5).In the process of dynamic changes(pathological changes),the ground glass shadow decreased gradually,the consolidation shadow increased first and then decreased,and the fiber cords increased gradually.On the 6th to 9th day of admission,the lesions progressed to different degrees and varied in morphology.The lesions were gradually absorbed after 10-14 days.Conclusion:The CT manifestations of the COVID-19 have certain characteristics,and the dynamic changes were regular.These characteristics and rules are important for early diagnosis,early isolation,early treatment and efficacy evaluation.
