Some researchers have tried to apply artificial intelligence in CT image analysis to differentiate COVID-19 from other viral pneumonia patients. With clinical symptoms, laboratory testing results, and contact or travel history, the artificial intelligence system can help doctors identify patients with risk of progressing to a more severe disease state at the time of admission, for timely, precise, and effective treatment decisions. Hence, precise lesion labelling, segmentation, and quantification analysis of COVID-19 lesions is the future of artificial intelligence.
