Выбрано 27 очагов, не отграниченных от сосудистых структур и плевры. С помощью линейной регрессионной модели было изучено влияние размеров очага, площади его соприкосновения с прилежащими структурами на вариабельность результатов.</p></sec><sec><title>Результаты</title><p>Результаты.

При некорректных результатах автоматического оконтуривания волюметрия очагов может быть проведена после ручной коррекции контуров с учетом допускаемой ошибки. При оценке динамики изменений коррекция контуров должна осуществляться одним и тем же человеком.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective.

Twenty-seven nodules uncircumscribed from the vascular structures and pleura were selected.

The linear regression model based on contact area and nodule size can correctly predict volumetry variability.</p></sec><sec><title>Conclusion</title><p>Conclusion. Even after manual segmentation volumetry remain suitable method for size assessment of lung nodules. Segmentation should be made with the same person because of significant difference of interobserver and intraobserver variabilities.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>волюметрия</kwd><kwd>морфометрия</kwd><kwd>компьютерная томография</kwd><kwd>очаги в лёгких</kwd><kwd>оценка ответа на лечение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>volumetry</kwd><kwd>morphometry</kwd><kwd>computed tomography</kwd><kwd>lung nodules</kwd><kwd>assessment of treatment response</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Therasse P., Arbuck S.G., Eisenhauer E.A., Wanders J., Kaplan R.S., Rubinstein L. et al.
