| 目的探讨新型冠状病毒肺炎( Corona Virus Disease 2019，COVID-19)的 CT影像表现及其诊断价值。方法回顾性分析 2020年 1—2月就诊于阜阳市第二人民医院 113例经 CDC实验室核酸确诊的 COVID-19 CT检查的病变表现形式、分布特点及病变程度。结果 COVID-19病人的 CT检查最主要影像表现:早期两肺外周带( 92.9%)多发磨玻璃样影(占 84.9%)，其内血管增粗(占 79.6%)；进展期，短期内病灶范围增大，密度增高，部分出现实变(占 84.4%)内见充气支气管征；重症期病变短期内进展迅速，病灶弥漫，部分呈“白肺”表现；吸收期，实变密度减低，病变范围缩小，部分可，见纤维索条(占 86.7%)。结论新型冠状病毒肺炎 CT表现具有特异性，不同时期的 CT表现，结合病人流行病学史、临床表现、典型影像学征象和病原学检查能够更为精准地诊断。 |

| Objective To investigate the CT imaging manifestations and its diagnostic value of Corona Virus Disease 2019(COVID -19).Methods The pathological manifestation，distribution characteristics and severity of the lesions in 113 patients who were di- agnosed as COVID-19 by CDC laboratory nucleic acid in the Second People’s Hospital of Fuyang City from January to February 2020 were analyzed retrospectively.Results The common CT findings in patients with COVID-19 infection were concluded.In ear- ly state，there were multiple ground glass opacities(accounting for 84.9%)in lung peripheral area(92.9%)and thickening inter- nal pulmonary vessels(accounting for 79.6%).In advanced stage，the scope of the lesion expanded and the density increased in a short period of time.Meanwhile，consolidation(84.4%)and inflatable bronchitis appeared in some lesions.In severe stage，the infec- tion proceeded rapidly.There were diffuse infiltration and white lung in some CT imaging.The density of the lesion decreased andthe lesion area was reduced in absorption period.Fiber chords(86.7%)were visible in some cases.Conclusion CT finding of CO- VID-19 have some specific characteristics.The diagnosis of COVID-19 could be more accurate by combining with the epidemiologi- cal history，clinical manifestations，typical imaging signs and pathogenic examination. |
