Evaluation of lung densitometric and volumetric changes in silicosis patients using three-dimensional software for multidetector CT and the relationship with profusion scores

•The first radiological parameter affected in silicosis is lung volume. •High opacity percentage shows high correlation with ILO classification. •Opacity score shows a moderate correlation with the ILO classification. •MDCT examination is an effective radiological modality to evaluate the severity of silicosis. Aim To evaluate the density and volume changes in the lungs of silicosis patients and their relationship with the disease severity...
