Brief Summary
In interstitial lung disease (ILD), the extent of ILD on chest computed tomography (CT) is recognized as an important prognostic factor. Automated tools are now available to quantify ILD, but there is a lack of data on the reproducibility of this measurement and therefore its accuracy. Therefore, the purpose of this study is to evaluate the variability of automated ILD quantification on chest CT. Reproducibility will be assessed by repeating chest CT scans and using different tools to measure the extent of disease.
