The aim of this study: to assess the ability of different software products to automated volumetric quantification of lung emphysema and see whether the results can be interconvertible.Materials and methods. This study is based on the results of recognition and analysis of computer tomograms using three different software products.Results: all the programs we used have high sensitivity and specificity in recognition of lung emphysema. However, there are a number of errors that prevent accurate image analysis.Conclusions. The interconvertibility of the results of the automated volumetric quantification of lung emphysema at this stage is not reliably determined and depends on the choice of software products used for analysis.
