To investigate the success of different quantitative lung assessment (QLA) methods on high-resolution CT (HRCT) to assess the severity of Sjogren's syndrome (SjS) related interstitial lung disease (ILD). ⋯ The QLA methods are a promising alternative to the Goh score in the objective evaluation of SjS-related ILD. The QLA methods are capable of distinguishing extensive (which is responsible for poor prognosis in SjS patients) from limited ILD.

To analyse the high-resolution computed tomography (HRCT) early imaging features and the changing trend of coronavirus disease 2019 (COVID-19) pneumonia. ⋯ The typical early CT features of COVID-19 pneumonia are ground-glass opacity, and located peripheral or subpleural location, and with supply pulmonary artery dilation. Reticulation was evident after the 2nd week and persisted in half of patients evaluated in 4 weeks after the onset. Long-term follow-up is required to determine whether the reticulation represents irreversible fibrosis.
