Картирование макромолекулярной протонной фракции (MПФ) является верифицированным методом количественного определения миелина, который адаптирован для пренатальных исследований.ЦЕЛЬ: Исследовать взаимосвязь между аномалиями МТ и пренатальной миелинизацией головного мозга с помощью метода картирования макромолекулярной протонной фракции (МПФ).МАТЕРИАЛЫ И МЕТОДЫ: МРТ головного мозга плодов были выполнены на томографе 1,5 Т (Achieva, Philips) с использованием 16-канальной катушки для тела. Из 66 МРТ головного мозга плодов в исследование отобраны 12 с аномалиями МТ (22,8±2,8, 19–28,5 недель гестации) и 21 без патологии головного мозга (23,1±2,3, 20–29,5 недель гестации). Анализ МРТ-изображений производился по данным структурной МРТ (Т2-Ssh и Т1-GE, EPI, DWI, MYUR, T2-BFFE-DYN) двумя опытными радиологами. Использовался метод быстрого 3D-сканирования с реконструкцией МПФ-карт по специализированному протоколу (https://www.macroatomicmri.org/). Получены количественные показатели МПФ путем выделения областей интереса в мосте, продолговатом мозге, таламусе, мозжечке и полушариях головного мозга. Статистика: ANCOVA с повторными измерениями, корреляционный анализ Пирсона.РЕЗУЛЬТАТЫ: При аномалиях МТ выявлены достоверно большие значения МПФ в продолговатом мозге (3,26±0,63% и 2,75±0,59%, р=0,001) и мозжечке (2,02±0,55% и 1,76±0,34%, р=0,006) в сравнении с контрольной группой. Также выявлена значимая корреляция МПФ с гестационным возрастом в белом веществе полушарий (r=0,81, р=0,002), которая отсутствует в контрольной группе (r=0,32, р=0,16).ЗАКЛЮЧЕНИЕ: При аномалиях МТ обнаружены статистически значимое увеличение значений и скорости миелинизации в продолговатом мозге и мозжечке соответственно; зависимость миелинизации больших полушарий от гестационного возраста, что может свидетельствовать о раннем компенсаторном ремоделировании аксонов при редукции межполушарных связей.</p></abstract><trans-abstract xml:lang="en"><p>INTRODUCTION: There is evidence, indicate early compensatory axonal remodeling connections in the prenatal period, providing a favorable neurological outcome in isolated anomalies of the corpus callosum (CC). Mapping of the macromolecular proton fraction (MPF) is proven method of quantitative determination of myelin, which has been adapted for prenatal studies.OBJECTIVE: To investigate the relationship between CC anomalies and prenatal myelination of the brain using the fast macromolecular proton fraction (MPF) mapping.MATERIALS AND METHODS: Fetal MR imaging were performed on a 1.5 scanner (Achieva, Philips) using a 16-channel body coil. Of 66 fetal brains MRI, 12 studies were selected with MT abnormalities (22.8±2.8, 19–28.5 WG) and 21 without brain pathology (23.1±2.3, 20–29.5 WG). The images were analyzed according to structural MRI data (T2-Ssh and T1-GE, EPI, DWI, MYUR, T2-BFE-DYN) by two experienced radiologists. Fast-3D-MPF scan protocol with the MPF maps reconstruction was carried out according to a specialized protocol (open-source software: https://www.macroatomicmri.org /). Quantitative data were obtained by choosing the region of interest (ROI) in numerous brain structures bilateral (bridge, medulla oblongata, thalamus, cerebellum, and cerebral hemispheres). Statistics: distinctions between the groups and structures were assessed using repeated-measures analysis of covariance (ANCOVA), Pearson correlation analysis.RESULTS: MPF was significantly increased in the CC anomalies group as compared to controls in the medulla (3.26±0.63% vs. 2.75±0.59%, р=0.001) and cerebellum (2.02±0.55% vs. 1.76±0.34%, р=0.006). In hemispheres significant correlation with GA was observed in CC anomalies group (r=0.81, р=0.002), but was absent in controls (r=0.32, р=0.16).CONCLUSION: Primary observed MPF increase in the medulla and cerebellum as well as the dependence of the large hemispheres myelination on gestational age indicates that fetal cerebral matter undergoes early compensatory axonal remodeling in the cases of the interhemispheric connections’ reduction.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аномалия мозолистого тела</kwd><kwd>миелинизация</kwd><kwd>МРТ плода</kwd><kwd>пренатальная диагностика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>аnomaly of the corpus callosum</kwd><kwd>myelination</kwd><kwd>fetal MRI</kwd><kwd>prenatal diagnosis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Мы благодарим Министерство науки и высшего образования РФ (АААА-А21-121012290041-9) за доступ к оборудованию.
