Radiomics explained 71.1% of the variability in FVC compared with 51.4% by Scadding staging alone.Conclusions Radiomic HRCT measures objectively differentiate disease abnormalities, associate with lung function and identify trends in Scadding stage, showing promise as quantitative biomarkers for pulmonary sarcoidosis.Radiomic measures identify pulmonary parenchymal abnormalities in sarcoidosis and are highly associated with lung function, suggesting that radiomics could enhance visual reads and result in improved patient profiling, disease staging and monitoring. http://bit.ly/2HMLaKm ER -
