В данной работе МРТ использовалась в комплексе с традиционными подходами — овоскопией, анатомическим вскрытием и рентгенографией — для комплексного анализа эмбриогенеза уток. В исследование было включено 60 эмбрионов, за развитием которых осуществлялось ежедневное наблюдение с 1-го по 27-й день инкубации. Такой дизайн обеспечил возможность документирования ключевых этапов морфогенеза и сопоставления данных, полученных различными методами визуализации. МРТ позволила с высокой точностью визуализировать сосудистую систему, внутренние органы и формирование скелета, что было особенно информативно на поздних стадиях инкубации. Установлено, что к 22-му дню желточный мешок начинает втягиваться в брюшную полость, а к 27-му дню эмбрион достигает полного формирования и инициирует проклёв скорлупы. Сравнительный анализ подтвердил преимущества МРТ перед традиционными методами в аспекте непрерывного и достоверного мониторинга динамики органогенеза без нарушения целостности яйца. Особое значение имеет возможность раннего выявления морфологических изменений и потенциальных патологий, что открывает перспективы применения метода в фундаментальных исследованиях эмбриологии и в практике птицеводства. Полученные результаты указывают на то, что внедрение МРТ в систему контроля инкубации может способствовать повышению выживаемости эмбрионов, оптимизации технологических режимов и улучшению показателей воспроизводства. Таким образом, МРТ представляет собой эффективный инструмент как для научных исследований, так и для прикладных задач птицеводческой отрасли.</p></abstract><trans-abstract xml:lang="en"><p>Magnetic resonance imaging (MRI) has proven to be a highly effective non-invasive tool for the study of avian embryogenesis, enabling detailed visualization of internal structures without compromising egg integrity. In this study, MRI was combined with conventional approaches, including candling, anatomical dissection, and radiography, to provide a comprehensive evaluation of duck embryonic development. A total of 60 embryos were monitored daily from day 1 to day 27 of incubation, allowing the identification of key stages of growth and structural differentiation. MRI provided high-resolution three-dimensional images of the vascular system, internal organs, and skeletal structures, with particular sensitivity at later developmental stages. Notably, by day 22, the yolk sac began to retract into the abdominal cavity, and by day 27 the embryo reached complete formation and initiated shell pipping. Comparative analysis demonstrated that each method contributed unique information: ovoscopy allowed rapid assessment of embryo viability, radiography provided clear images of skeletal ossification, while MRI offered superior visualization of soft tissues and dynamic processes in real time. The strong concordance between MRI data and anatomical dissection confirmed the reliability of this technique for continuous, non-destructive monitoring of embryogenesis. The findings highlight the applicability of MRI not only as a fundamental research tool but also as a promising method for optimizing incubation protocols and improving poultry breeding practices. The ability to track organogenesis and morphological changes in vivo provides new opportunities for early detection of developmental abnormalities, assessment of environmental influences, and refinement of incubation management strategies.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>визуализация</kwd><kwd>эмбрион</kwd><kwd>утка</kwd><kwd>развитие</kwd><kwd>рентгенография</kwd><kwd>МРТ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>visualization</kwd><kwd>embryo</kwd><kwd>duck</kwd><kwd>development</kwd><kwd>radiography</kwd><kwd>MRI</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">Тодороски К., Ежкова А.М., Ежков В.О., Волков Р.А.
