В ФГБНУ “Российский научный центр хирургии им. акад. Б.В. Петровского” была выполнена МСКТ-аортография 95 пациентам (57 мужчин и 38 женщин, средний возраст составил 61,4 ± 15,6 года) с использованием протоколов двух- и трехзонного сканирования и выбором значения напряжения на рентгеновской трубке (80 и 100 kV) в зависимости от антропометрических характеристик пациента, а именно индекса массы тела (ИМТ). Были проведены сравнение параметров DLP (Dose Length Product, произведение дозы на длину) – поглощенная доза за все МСКТ-исследование с учетом протяженности области сканирования и количества повторных сканирований), эффективной дозы (Е), времени и протяженности сканирования, а также подсчет количества вводимого контрастного препарата между группами, обследованными с применением двух- и трехзонного протокола при напряжении на рентгеновской трубке 80 и 100 kV.Результаты. Анализ полученных данных показал, что значения DLP и E были статистически достоверно ниже при использовании протокола МСКТ-аортографии, состоящего из трех зон сканирования (при 80 kV p = 0,008, при 100 kV р &lt; 0,001). При этом отсутствовала достоверная разница протяженности области исследования в группах с одинаковым напряжением на рентгеновской трубке (р = 0,55), в группе с трехзонным протоколом время сканирования было достоверно ниже (р &lt; 0,001) и составляло 9,4 ± 0,5 с / 10,24 ± 0,9 с (80 kV / 100 kV), что позволило существенно снизить лучевую нагрузку (до 40%) и объем вводимого контрастного препарата (на 20%).Заключение. Использование трехзонного протокола МСКТ-аортографии с индивидуальным выбором напряжения на рентгеновской трубке оправданно и позволяет значительно снизить лучевую и йодную нагрузку в сравнении с двухзонным cканированием при сохранении высокого качества получаемых изображений.</p></abstract><trans-abstract xml:lang="en"><p>Objective. The comparison of protocols of computed tomography (CT) angiography of the aorta and their modification in conditions of radiation and iodine load reducing on the patient.Methods. In 95 patients (57 men, 38 women, mean age 61.4 ± 15.6 years) CT angiography of the aorta was performed using two- and three-zone scanning protocols with the voltage value on the X-ray tube (80 and 100kV) depending on the anthropometric measure namely body mass index (BMI). We compared dose length product parameters (DLP), effective dose (E), time and duration of scanning, as well as counting the amount of injected contrast agent (CM) between groups examined using a two-zone and three-zone protocols at an X-ray tube voltage of 80 and 100kV.Results. Analysis of the data obtained showed that the DLP and E values were statistically significantly lower with the CT angiography of the aorta protocol, which consisted of three scanning zones (at 80kV p = 0.008; at 100kV p &lt; 0.001). At the same time, there was no significant difference in the length of the study area in groups with the same voltage on the X-ray tube (p = 0.55), in the group with a three-zone protocol, the scanning time was significantly lower (p &lt; 0.001) and amounted to 9.4 ± 0.5 sec/10.24 ± 0.9 sec (80/100kV), which made it possible to significantly reduce radiation exposure up to 40% and the amount of injected contrast agent by 20%.Conclusions. The use of a three-zone CT-angiography of the aorta protocol with individual selection of voltage of the X-ray tube is justified and allows a significant reduction of radiation and iodine exposure compared to twozone scanning while maintaining the high images quality.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>МСКТ-аортография</kwd><kwd>аорта</kwd><kwd>ангиография</kwd><kwd>лучевая нагрузка</kwd><kwd>йодная нагрузка</kwd><kwd>кардиосинхронизация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>CT angiography of the aorta</kwd><kwd>radiation exposure</kwd><kwd>iodine exposure</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">Врожденный клапанный стеноз аорты (КСА): Клинические рекомендации МЗ РФ, 2016.</mixed-citation><mixed-citation xml:lang="en">Congenital valvular aortic stenosis (VAS): Clinical recommendations of the Ministry of Health of the Russian Federation, 2016.
