В исследование вошло 40 пациентов, которые были разделены на 2 группы по 20 человек в зависимости от применяемого протокола исследования: стандартный протокол “120 кВ” или модифицированный протокол “100 кВ”. Все исследования были выполнены с внутривенным введением контрастного препарата. Обрабатывали следующие данные томограмм: шум, окружность брюшной полости, отношение контраст/шум, данные контрастного усиления органов. Томограммы реконструировали стандартным и итеративным алгоритмами реконструкции. Качественную оценку изображений проводили по 2 параметрам – оценка изображения в целом и визуализация образования по 3-балльной шкале.Результаты. Лучевая нагрузка снизилась на 31,5% при применении модифицированного протокола. Уровень шума не различался при применении стандартной реконструкции, однако выраженно снижался при применении итеративной реконструкции. Отношение контраст/шум оказалось выше в группе “100 кВ” и последовательно возрастало с повышением уровней итеративной реконструкции. Оценки визуализации образований были значимо выше в группе “100 кВ”.Заключение. Применение протоколов сканирования с пониженной лучевой нагрузкой оправданно, оно позволяет серьезно снизить дозу облучения пациента, улучшить визуализацию образований печени и поджелудочной железы (в первую очередь гиперваскулярных). Применение алгоритмов итеративной реконструкции позволяет добиться значимого улучшения качества изображения и снижения шума.</p></abstract><trans-abstract xml:lang="en"><p>Aims: to evaluate the possibilities of low-dose MDCT protocols in visualization of liver and pancreatic tumors.Materials and methods. 40 patients were enrolled in study and divided into 2 groups. Two scanning protocols were used, differing by the voltage on the X-ray tube-standard 120 kV, and the modified 100 kV. All studies were performed with intravenous administration of a contrast agent. The data – noise, a circumference of abdominal cavity, a relation “contrast-noise”, data of contrast strengthening of organs were evaluated. The tomograms were reconstructed using standard and iterative reconstruction algorithms. A qualitative assessment of the images was carried out according to 2 parameters – the evaluation of the whole image and the visualization of tumor on a 3-point scale.Results. Radiation exposure decreased by 31.5% using the modified protocol. The noise level did not differ with the use of standard reconstruction, but it decreased markedly using iterative reconstruction. The contrast-to-noise ratio turned out to be higher in the “100 kV” group and consistently increased with increasing levels of iterative reconstruction. Evaluations of the visualization of tumors were significantly higher in the “100 kV” group.Conclusion. The use of low-dose protocols is justified, it allows to seriously reduce the radiation exposure, improving visualization of the liver and pancreas tumors (primarily hypervascular). Application of iterative reconstruction algorithms allows achieving significant improvement in image quality and noise reduction.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>лучевая нагрузка</kwd><kwd>низкое напряжение</kwd><kwd>протокол пониженной лучевой нагрузки</kwd><kwd>радиация</kwd><kwd>гиперваскулярное образование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>radiation exposure</kwd><kwd>low voltage</kwd><kwd>low-dose protocol</kwd><kwd>radiation</kwd><kwd>hypervascular tumor</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">Тюрин И.Е.
