Pneumonia after neocoronavirus infection has relative specificity in CT imaging, and the early manifestations are mainly small patchy shadows in the lungs and ground-glass-like lesions, mainly distributed in the outer bands of the lungs. With the progression of the disease, the scope of the patients’ ground-glass and patchy shadows can gradually expand, and some patients even have large solid lesions, entering the state of respiratory distress and respiratory failure. Early CT as the diagnosis of new crown pneumonia has specificity and plays a very important role in clinical diagnosis, even in the case of negative nucleic acid test, the specific performance of lung CT can help clinical diagnosis of new crown pneumonia patients. Experienced radiologists, including clinicians, can determine the likelihood of a patient having a new crown pneumonia based on CT. Source: Dr. Yurai
