Clinical application of HRCT in diagnosis and treatment of novel coronavirus pneumonia

Objective To explore the CT manifestations of(COVID-19)and to assess the diagnostic value of quantitative CT pulmonary function in the clinical classification of corona virus disease 2019.Methods Totally,31 COVID-19 patients confirmed by virus nucleic acid detection were collected.All patients had completed dynamic chest HRCT imaging data.The relation between the quantitative CT pulmonary function and clinical classification of corona virus disease 2019 were analyzed.Results All 31 patients underwent chest HRCT within 3 days after onset.The decectable rate of COVID-19 was 100%(31/31).About 5~7 days after onset,all the patients underwent the first time re-examination of HRCT,the lesion scope enlarged in 21 cases(21/31,67.74%)but reduced in 6 cases(6/31,19.35%),the lesion range remained the same like before in 4 cases(4/31,12.90%)and about 10~14 days after onset,all the patients underwent the second time re-examination of HRCT,the lesion scope reduced in 26 cases(26/31,83.87%)but enlarged in 3 cases(3/31,9.67%).There was a significant negative correlation between the quantitative CT pulmonary function and the clinical classification of COVID-19.Conclusion HRCT can clearly show imaging changes of the COVID-19 in time.The quantitative CT pulmonary function was correlated with the clinical classification of COVID-19,which is helpful to guiding early clinical diagnosis,early treatment,and providing evidence for evaluating the effect of clinical treatment of COVID-19.
