Использована многоэховая эхопланарная последовательность для получения серии изображений с разными временами эха за одну задержку дыхания. Для расчета Т2* применен ROI-анализ (region of interest, область интереса) вручную размеченных областей белого вещества с экспоненциальной аппроксимацией сигнала. Методика адаптирована к ограничениям пренатальной МРТ: движению плода, влиянию амниотической жидкости, диэлектрическим искажениям на 3 Тл и необходимости компромисса между разрешением и временем сканирования.</p></sec><sec><title>Результаты</title><p>Результаты. Метод обеспечил воспроизводимые значения Т2* у плодов во II–III триместрах: 182 ± 11 мс на 1,5 Тл и 153 ± 13 мс на 3 Тл, что превышает показатели у взрослых (66,2 ± 2,5 и 51,8 ± 2,9 мс соответственно). Согласие между двумя методами расчета Т2* оказалось высоким (внутриклассовый коэффициент корреляции 0,955, p &lt; 0,0001). Метод перспективен для оценки гипоксии у плода.</p></sec><sec><title>Заключение</title><p>Заключение. При правильной настройке сканирования и постобработки Т2*релаксометрия может быть успешно применена в пренатальной МРТ. Предложенные решения преодолевают ключевые ограничения и открывают путь к дальнейшему клиническому и научному использованию метода.</p></sec></abstract><trans-abstract xml:lang="en"><p>Aim of the study was to propose a practical method for T2*-relaxometry of fetal brain white matter using prenatal MRI, adapted to real-world clinical conditions and the specific limitations of prenatal imaging.</p><sec><title>Material and Methods</title><p>Material and Methods. A multi-echo echo-planar imaging (EPI) sequence was used to acquire a series of images with different echo times within a single breath-hold. T2* values were calculated using ROI (region of interest) analysis of manually annotated white matter regions, with exponential fitting of the signal decay. The method was adapted to the constraints of prenatal MRI, including fetal motion, the influence of amniotic fluid, dielectric artifacts at 3T, and the need to balance resolution with scan time.</p></sec><sec><title>Results</title><p>Results. The method yielded reproducible T2* values in fetuses during the second and third trimesters: 182 ± 11 ms at 1.5T and 153 ± 13 ms at 3T, both higher than those in adults (66.2 ± 2.5 and 51.8 ± 2.9 ms, respectively). Agreement between two T2* calculation methods was high (intraclass correlation coefficient 0.955, p &lt; 0.0001). The method shows promise for assessing fetal hypoxia.</p></sec><sec><title>Conclusions</title><p>Conclusions. With appropriate scanning and post-processing settings, T2*-relaxometry can be successfully applied to prenatal MRI. The proposed solutions overcome key limitations and pave the way to further clinical and research use of the method.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>пренатальная МРТ</kwd><kwd>Т2*-релаксометрия</kwd><kwd>гипоксия мозга плода</kwd><kwd>фантомное моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>prenatal MRI</kwd><kwd>T2*-relaxometry</kwd><kwd>fetal brain hypoxia</kwd><kwd>phantom modeling</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № 25-25-00023 (https://rscf.ru/project/25-25-00023/).
