CT features and dynamic changes of novel coronavirus pneumonia

Objective To correctly understand the CT features of the novel coronavirus pneumonia(NCP) is of great clinical signifi.cance for the diagnosis and evaluation of curative effect.Methods A total of 91 NCP patients in The Second People''s Hospital of Fuy.ang with positive diagnosis by CDC nucleic acid detection in Anhui province or Fuyang city were collected from January to February2020. The chest CT manifestations of all cases were analyzed retrospectively.Results The early manifestations of NCP were mainlynodular and patchy ground glass shadow located in the subpleural area (including the interlobular pleura) of single or bilateral lung,with diffuse fine grid shadows, "air bronchogram", "small vascular enlargement" and "halo sign"; In the advanced stage, the lesions in.creased with partial consolidation, and developed along the subpleural and bronchial blood vessel bundle to the direction of the hilarlung. The diffuse consolidation shadow in bilateral lung could be seen in severe cases. In a few cases, there were lymph node enlarge.ment in hilum and mediastinal, and a small amount of pleural effusion. There were only a few ground glass shadow and fibrous cordshadow in the absorption of lung lesions during the dissipation period.Conclusion The CT manifestations of NCP have certain charac. teristics, which can make a more accurate diagnosis combined with patient epidemiology history, clinical manifestations, typical imag.ing manifestations and sample nucleic acid detection. CT is one of the important means to evaluate the scope of lesions and clinical cu.rative effect for NCP.
