Точная идентификация и анализ легочных узелков с помощью компьютерной томографии имеют решающее значение для диагностики рака легких и выявления генетических изменений, таких как мутации рецептора эпидермального фактора роста (еpidermal growth factor receptor, EGFR). Хотя традиционная радиомика стала основой медицинской визуализации, ее прогностическая ценность для определения статуса мутации EGFR остается ограниченной, что требует инновационных подходов для повышения надежности диагностики. Цель: повысить точность прогнозирования статуса мутации EGFR в легочных узелках путем внедрения и интеграции новых текстурных радиомических признаков в традиционный радиомический анализ. Материал и методы. Разработаны три новых радиомических признака: адаптивный контраст текстуры (Adaptive Texture Contrast, ATC), направленная однородность текстуры (Directional Texture Uniformity, DTU) и совместная встречаемость переходов текстуры (Co-occurrence of Texture Transitions, CTT). Они предназначены для выявления сложных текстурных паттернов, связанных с мутациями EGFR. С использованием этих признаков применяется классификационная модель для различения легочных узелков с мутацией EGFR от узелков дикого типа. Результаты. Включение ATC, DTU и CTT в набор радиомических признаков повысило точность классификации на 4%. Метод отбора признаков «минимум избыточности, максимум релевантности» (Minimum Redundancy Maximum Relevance, MRMR) дополнительно подтвердил значимость данных признаков, определив их основной вклад в прогностическую эффективность модели. Заключение. Результаты исследования указывают на потенциал передового анализа текстур в улучшении диагностических возможностей радиомики для классификации легочных узелков. Полученные данные обеспечивают более точное прогнозирование мутаций EGFR, способствуют развитию персонализированной медицины и таргетных стратегий лечения рака легких, подчеркивая важность постоянных инноваций в инженерии признаков.</p></abstract><trans-abstract xml:lang="en"><p>Background. Accurate identification and analysis of lung nodules via computed tomography are pivotal for lung cancer diagnosis and the detection of genetic alterations, such as epidermal growth factor receptor (EGFR) mutations. While conventional radiomics has become a cornerstone of medical imaging, its predictive power for determining EGFR mutation status remains limited, necessitating innovative approaches to improve diagnostic reliability. Objective: to enhance the accuracy of EGFR mutation status prediction in lung nodules by introducing and integrating novel texture-based radiomics features into conventional radiomics analysis. Material and methods. Three novel radiomic features were developed: Adaptive Texture Contrast (ATC), Directional Texture Uniformity (DTU), and Co-occurrence of Texture Transitions (CTT). They were designed to capture complex texture patterns associated with EGFR mutations. Integrating these features, a classification model was employed to differentiate EGFR mutant from wild-type lung nodules. Results. The incorporation of ATC, DTU, and CTT into the radiomics feature set improved the classification accuracy by 4%. The Minimum Redundancy Maximum Relevance (MRMR) feature selection method further validated the significance of these features, ranking them as the top contributors to the model’s predictive performance. Conclusion. The findings underscore the potential of advanced texture analysis in improving the diagnostic capabilities of radiomics for lung nodule classification. By enabling more accurate predictions of EGFR mutations, the study supports the advancement of personalized medicine and targeted treatment strategies in lung cancer, highlighting the importance of continuous innovation in feature engineering.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>классификация легочных узелков</kwd><kwd>мутация EGFR</kwd><kwd>радиомика</kwd><kwd>анализ текстур</kwd><kwd>разработка признаков</kwd><kwd>вычислительная диагностика</kwd><kwd>персонализированная медицина</kwd><kwd>машинное обучение</kwd><kwd>отбор признаков MRMR</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lung nodule classification</kwd><kwd>EGFR mutation</kwd><kwd>radiomics</kwd><kwd>texture analysis</kwd><kwd>feature engineering</kwd><kwd>computational diagnostics</kwd><kwd>personalized medicine</kwd><kwd>machine learning</kwd><kwd>MRMR feature selection</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при поддержке гранта Российского научного фонда (РНФ) № 24-25-00204 (https://rscf.ru/project/24-25-00204)</funding-statement><funding-statement xml:lang="en">This research was funded by Russian Science Foundation (RSF), grant No. 24-25-00204 (https:// rscf.ru/en/project/24-25-00204)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Shariaty F, Pavlov VA, Zavyalov SV, et al.
