Typical features on chest X-Ray
Multiple small patchy shadows and interstitial changes in the lower zone of lungs are typical imaging features in common type patients. With the progression of the disease, it may manifest as a patchy distribution or multiple consolidations. In severe and critical type COVID-19 pneunomia, multifocal or diffuse consolidation can be seen in both lungs, showing as “white lung”. Chest X-ray is only suitable for primary hospitals without examination conditions and follow up of critically ill patients.
