新型冠状病毒肺炎胸部CT影像学特点分析

Analysis of CT imaging features of COVID-19 chest

目的:探讨新型冠状病毒肺炎(NCP)的胸部CT影像表现特点,评价其诊断价值,为临床诊断及治疗提供客观依据。方法:选取2020年1月23日—2020年2月20日我院8例新型冠状病毒肺炎确诊患者作为研究对象,分析其胸部影像CT特点。结果:8例均有磨玻璃状阴影,实变3例,斑片状阴影1例,空气支气管征3例,网格征4例,血管增粗征3例,胸膜增厚及支气管壁增厚各1例。单肺受累5例,双肺受累3例。未见肺门、纵膈淋巴结肿大及胸腔积液。结论:新型冠状病毒肺炎患者的胸部CT影像学表现相对具有特征性,对于及时指导临床诊断及治疗具有重要意义。

Objective To explore the characteristics of chest CT images of COVID-19(NCP),evaluate its diagnostic value,and provide objective basis for clinical diagnosis and treatment.Methods From January 23,2020 to February 20,2020,8 patients diagnosed by COVID-19 in our hospital were selected as the subjects,and the CT features of chest images were analyzed.Results All the 8 cases had ground glass shadow,3 cases of consolidation,1 case of patchy shadow,3 cases of air bronchus sign,4 cases of grid sign,3 cases of vascular thickening sign,1 case of pleura thickening and 1 case of bronchial wall thickening.There were 5 cases of single lung involvement and 3 cases of bilateral lung involvement.No hilar,mediastinal lymph node enlargement and pleural effusions were found.Conclusion The chest CT imaging findings of COVID-19 patients are relatively characteristic,which is of great significance for guiding clinical diagnosis and treatment in time.
