Исследование лучевых осложнений после облучения легких у крыс с помощью облучателя с визуальным контролем SmART+ (Precision, Северный Бранфорд, Коннектикут, США) является пилотным для разработки модели радиационно-индуцированной легочной токсичности на животных.</p><sec><title>Цель работы</title><p>Цель работы: определение дозы и объема облучения мишени в легких у крыс, при которых характерно развитие лучевого пневмонита.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследовании были определены 4 группы крыс линий Wag и Wistar, отличающиеся возрастом (10–16,5 мес.) и весом (350–850 г). Облучение мишени в легком проводилось с предварительным дозиметрическим планированием в статическом или ротационном режимах, различными дозами (от 10 до 30 Гр), объемами мишени в легком (0,045–1,24 см3) и локализацией (левое или правое легкое, верх или низ легкого). Дозиметрическое планирование обеспечивает оптимальное лучевое воздействие на мишень и контроль дозовых нагрузок на органы риска. Развитие лучевых повреждений наблюдалось на КТ сканированиях в течение 16 нед.</p></sec><sec><title>Результаты</title><p>Результаты. Для получения плотности легких крыс (в единицах Хаунсфилда) было проведено КТ сканирование здоровых животных, выполнена обработка снимков, определены среднее значение и стандартное отклонение плотности. Значения плотности легких крыс (в единицах Хаунсфилда) составили – 519,6 ± 46,2 (контрольные значения). Выполнено сравнение экспериментальных данных для облученных животных и контрольных значений. В результате анализа установлена зависимость объема мишени, подведенной дозы и выживаемости животных после облучения. Показано, что параметр «среднее значение плотности легкого (в единицах Хаунсфилда)» может использоваться для количественного анализа изменений в легком после облучения.</p></sec><sec><title>Выводы</title><p>Выводы. Определены доза и объем облучения мишени в легких у крыс, при которых характерно развитие лучевого пневмонита. При дозе облучения 16 Гр и объеме облученного легкого не менее 0,5 см3  (8%) характерно появление участка снижения пневматизации в зоне облучения.</p></sec></abstract><trans-abstract xml:lang="en"><p>The clinical application of the results of the experimental radiotherapy on animals is currently not widely used. The research of radiation injuries after irradiation target in rat lungs using the image-guided platform SmART+ (Precision, North Branford, Conn., USA) is a pilot study for the establishment of an animal model of radiation-induced pulmonary toxicity.</p><sec><title>Aim</title><p>Aim: To define the typical doses and target volumes in rat lung to o serve radiation pneumonitis.</p></sec><sec><title>Material and methods</title><p>Material and methods. Four groups of Wistar and Wag rats, distinguishing by age (10–16,5 months) and weight (350-850 g.), were studied. Dosimetric treatment plans were calculated prior to irradiation, using arc or static methods, doses (10–30 Gy), target lung volumes (0,045–1,24 cm3), localization (right or left, top or bottom). Dosimetric planning provides optimal radiation exposure to the target and controls organ at risk doses. Computer tomography (CT) scans were performed for 16 weeks to observe radiation pneumonitis</p></sec><sec><title>Results</title><p>Results. To obtain the rat lung density in Hounsfield units (HU), healthy animals were scanned, CT images were processed, and the mean and standard deviation were calculated. Lung density values of rats (control values) are 519.6 ± 46.2 (HU). Comparison of experimental data on irradiated animals and control values was carried out. As a result, the relationship of the target volume, the delivered dose and the survival rate of animals after irradiation was established. It was shown that the “mean value of lung density” could be used for quantitative analysis of lung injuries after irradiation.</p></sec><sec><title>Conclusion</title><p>Conclusion. Typical doses and target volumes in rat lungs to observe radiation pneumonitis were obtained. Decreasing aeration of lung tissue was derived at delivered dose 16 Gy and irradiated target volume in lung at least 0.5 cm3 (8%).</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>лучевой пневмонит</kwd><kwd>облучение легких крыс</kwd><kwd>КТ сканирование</kwd><kwd>плотность легкого в единицах Хаунсфильда</kwd></kwd-group><kwd-group xml:lang="en"><kwd>radiation pneumonitis</kwd><kwd>rat lung irradiation</kwd><kwd>CT scan</kwd><kwd>lung density in Hounsfield units</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">Vinod S.
