CT磨玻璃影像改变对新型冠状病毒肺炎不同阶段的诊断意义

Diagnostic Value of CT Ground Glass Image Changes on COVID-19 of Different Stages

分析CT磨玻璃影像改变对新型冠状病毒肺炎不同阶段的诊断意义。选取386例因呼吸道症状或发热就诊且接受胸部CT检查的患者为样本,实施CT检查,对比GGO影像特点于症状出现3 d内以及3 d之后的临床价值。新冠肺炎病患CT、GGO密度/部分实性改变、沿支气管束分布、同时合并小叶间隔厚度增加的GGO特点对各个阶段新冠肺炎的诊断有重要价值。

The research analyzes the diagnostic significance of CT ground glass image changes on COVID-19 of different stages.386 patients who see doctors because of respiratory symptoms or fever,and receive chest CT examination are selected as the research sample.CT examination is implemented.Clinical values of GGO image characteristics on symptom appearance within 3 d and after 3 d are compared.GGO characteristics,such as CT,GGO density/part real changes,distribution along the bronchial bundle and the combination with interlobular septal thickness,have important value on COVID-19 diagnosis of all stages.
