CT image visual quantitative evaluation and clinical classification of coronavirus disease (COVID-19)

The authors of this study analysed COVID-19 patients from Zhuhai, China to compare the relationship between the imaging manifestations and clinical classification of the disease. Based on the sample of 78 patients falling into all 3 categories of the disease (mild, common, and critical), the authors concluded that CT was not suitable as an independent screening tool, but that CT visual quantitative analysis has high consistency and can reflect the clinical classification of COVID-19.
