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

Novel coronavirus pneumonia (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, understanding 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 described the imaging manifestation of lung infectious mainly shown 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
