Limitation
There were several limitations in this study. First, none of the
patients underwent
a lung
biopsy or autopsy, because of the comparatively better outcomes of the
patients in this study. Therefore, the HRCT findings of the lung could
not be verified
by histopathology.
Finally, this was a study with initial HRCT images during
hospitalization, mainly demonstrated the
early pulmonary
lesions in patients with COVID- further longitudinal research was
needed to focus on the long-term follow-up, to provide dynamic HRCT
evaluation for pulmonary lesions and to obtain the data of long-term
pulmonary function changes.
