Resumen
Background: A pneumonia associated with the coronavirus disease 2019 (COVID-19) recently emerged in
China. It was recognized as a global health hazard.
Methods: 234 inpatients with COVID-19 were included. Detailed clinical data, chest HRCT basic
performances and certain signs were recorded Ground-glass opacity (GGO), consolidation, fibrosis and
air trapping were quantified. Both clinical types and CT stages were evaluated.
Results: Most patients (approximately 90%) were classified as common type and with epidemiologic
history. Fever and cough were main symptoms. Chest CT showed abnormal attenuation in bilateral
multiple lung lobes, distributed in the lower and/or periphery of the lungs (94.98%), with multiple
shapes. GGO and vascular enhancement sign were most frequent seen, followed by interlobular septal
thickening and air bronchus sign as well as consolidation, fibrosis and air trapping. There were significant
differences in most of CT signs between different stage groups. The SpO2 and OI were decreased in stage
IV, and the CT score of consolidation, fibrosis and air trapping was significantly lower in stage I (P<0.05).
A weak relevance was between the fibrosis score and the value of PaO2 and SpO2 (P< 0.05).
Conclusions: Clinical performances of patients with COVID-19, mostly with epidemiologic history and
typical symptoms, were critical valuable in the diagnosis of the COVID-19. While chest HRCT provided the
distribution, shape, attenuation and extent of lung lesions, as well as some typical CT signs of COVID-19
pneumonia.
