以磨玻璃影为主要表现的肺部感染性病变影像学鉴别诊断

 

新型冠状病毒病（COVID-19）已成为全球突发公共卫生事件。计算机断层扫描（CT）对于COVID-19的诊断及鉴别诊断非常重要，了解COVID-19的影像学表现有利于提高诊断的正确率。COVID-19肺部影像学表现主要为磨玻璃影，基于此，本文对以磨玻璃影为主要表现的肺部感染性病变的影像学表现进行阐述，比较冠状病毒科与非冠状病毒科，以及其他病原体所致肺炎影像学的差异，以期帮助放射科及临床医生更好地进行临床诊断及鉴别诊断。

Differential diagnosis of lung infectious diseases shown as ground-glass opacity based on CT imaging

Coronavirus disease 2019 (COVID-19) has become a global public health emergency worldwide. Computerized tomography (CT) is very important for the diagnosis and differential diagnosis of COVID-19, understan-ding the imaging manifestation of COVID-19 will help to improve the accuracy of diagnosis. The main lung imaging manifestation of COVID-19 is ground-glass opacity, this paper describes the imaging manifestation of lung infectious diseases mainly shown as ground-glass opacity, imaging differences in pneumonia caused by coronaviridae, non-coronaviridae and other pathogens were compared, so as to help radiologists and clinicians make better clinical diagnosis and differential diagnosis.
