Changes of CT findings in a 2019 novel coronavirus (2019-nCoV) pneumonia patient

The gold standard for diagnosis of 2019 novel coronavirus (2019-nCoV) infection is the new coronavirus nucleic acid in swabs, sputum, secretions from the lower respiratory tract or blood. However, due to the quite low sensitivity, short of supply and a relatively long period of new coronavirus nucleic acid kits, suspected cases with false-negative results remain a severe problem. Besides, a long incubation period (3–7 days, up to 14 days) and superior transmission capacity of new viruses contribute to the fast spread of 2019-nCoV. Under the circumstances, computed tomography imaging is not only useful for the detection, location of lesions but also helpful in the evaluation of the dynamic changes of patients with 2019-nCoV.
