Диффузионно-тензорная визуализация (ДТВ) — методика, позволяющая оценить диффузию молекул воды вдоль миелиновой оболочки нервных волокон и получить информацию о целостности проводящих путей головного и спинного мозга (СМ). Получение воспроизводимых значений параметров диффузии является актуальной и выполнимой задачей. Цель работы — определить значения параметров ДТВ на всём протяжении СМ у здоровых детей для использования при оценке острой травмы, её последствий и других форм патологии СМ.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Обследовано 15 условно здоровых детей в возрасте 13–18 лет, из них 6 девочек, 8 мальчиков, средний возраст 15,2 ± 1,2 года. Разработан протокол МРТ позвоночника для охвата всего объёма СМ с раздельной визуа­лизацией шейного и грудного отделов позвоночника (длительность — 9 мин 48 с). Проведены построение карт и расчёт параметров диффузии: фракционной анизотропии (ФА), медиальной (МД), продольной или аксиальной (АД) и поперечной (ПД) диффузии. Для получения ДТВ-изображений использовали последовательность «IRIS ZOOM» («Philips»), для обработки данных — программный пакет «Spinal Cord Toolbox», для статистического анализа — программное обеспечение «GraphPad Prism», значимость критериев определяли на уровне p &lt; 0,05.</p></sec><sec><title>Результаты</title><p>Результаты. Средние значения параметров СМ детей составили: ФА = 0,63 ± 0,06; АД = 2,1 ± 0,3 × 10−3 мм2/с; МД = 1,15 ± 0,16 × 10−3 мм2/с; ПД = 0,68 ± 0,12 × 10−3 мм2/с. При этом выявлено повышение ФA на уровне Th2–Th9 по сравнению со значениями на уровнях C6–Th1 и Th10–Th12. Коэффициент АД на уровне Th2–Th9 был повышен относительно уровней C2–C5 и C6–Th1. Значения МД в зонах СМ на уровнях Th2–Th9 и Th10–Th12 были повышены относительно более высоких уровней СМ. Значения ПД в зоне на уровне Th10–Th12 повышены относительно всех остальных зон.</p></sec><sec><title>Заключение</title><p>Заключение. Определены показатели диффузии СМ детей в возрасте 12–18 лет и выявлены небольшие различия между областями СМ. Установленные значения могут быть использованы как референтные для оценки состояния СМ при различных формах патологии (травмах, демиелинизирующих и опухолевых заболеваниях) у детей соответствующей возрастной группы.</p></sec><sec><title>Участие авторов</title><p>Участие авторов: Ахадов T.A., Божко О.В., Ублинский М.В. — концепция и дизайн исследования; Божко О.В., Ублинский М.В., Кобзева А.А., Мельников И.А. — проведение исследования; Божко О.В., Ублинский М.В., Воронкова Е.В. — сбор и обработка материала; Ублинский М.В., Воронкова Е.В. — статистическая обработка; Божко О.В. — написание текста; Ахадов T.A., Ублинский М.В. — редактирование; Ахадов T.A., Божко О.В., Ублинский М.В. — утверждение окончательного варианта статьи.

Diffusion tensor imaging (DTI) is a technique that allows evaluating diffusion of water molecules along the myelin sheath of nerve fibers and obtaining information about the integrity of brain and spinal cord pathways. Obtaining reproducible values of diffusion parameters is an urgent and feasible task. The aim of this study was to establish the values of DTI parameters along the entire length of the spinal cord in healthy children for further use in the assessment of acute injury, its consequences and other spinal cord diseases.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included fifteen healthy patients of 13 to 18 years, including 6 girls and 8 boys, average age was 15.2 ± 1.2 years. The study was performed on a Philips Achieva dStream 3T MRI scanner (Netherlands). As part of this study, a spine MRI protocol was developed to cover the entire volume of spinal cord with separate visualization of cervical and thoracic spine (duration: 9 min 48 sec). The IRIS ZOOM sequence (Philips) was used to obtain DTI images. Spinal Cord Toolbox software package was used to process the data. Statistical analysis was performed using GraphPad Prism software, and significance was determined at p &lt; 0.05.</p></sec><sec><title>Results</title><p>Results. Mapping and calculation of the following diffusion parameters: fractional anisotropy (FA), medial (MD), longitudinal or axial (AD) and transverse (RD) diffusion showed the average values of the parameters FA, AD, MD, RD of the spinal cord of children to be: FA, AD, MD, RD of spinal cord were: FA = 0.63 ± 0.06, AD = 2.1 ± 0.3 × 10−3 mm2/s, MD = 1.15 ± 0.16 × 10−3 mm2/s, RD = 0.68 ± 0.12 × 10−3 mm2/s. An increase in FA was detected at the Th2–Th9 level compared to the values at the C6–Th1 and Th10–Th12 levels. The AD coefficient at the Th2–Th9 level is increased relative to the C2–C5 and C6–Th1 levels. MD values in spinal cord areas at the Th2–Th9 and Th10–Th12 levels are statistically higher relative to higher levels of the spinal cord. RD values in the zone at the Th10–Th12 level are increased relative to all other areas.</p></sec><sec><title>Conclusion</title><p>Conclusion. The study established the diffusion indices of FA, MD, AD, RD of spinal cord in children aged 12 to 18 years and showed small differences between the spinal cord regions. The data obtained can be used as reference values for assessing spinal cord condition in various pathological processes (trauma, demyelinating and tumor diseases) in children for the corresponding age group.</p></sec><sec><title>Contribution</title><p>Contribution: Akhadov T.A., Bozhko O.V., Ublinskiy M.V. — research concept and design; Bozhko O.V., Ublinskiy M.V., Kobzeva A.A., Melnikov I.A. — conducting research; Bozhko O.V., Ublinskiy M.V., Voronkova E.V. — collection and analysis of data; Ublinskiy M.V., Voronkova E.V. — statistical analysis; Bozhko O.V. — writing the text; Akhadov T.A., Ublinskiy M.V. — editing the text; Akhadov T.A., Bozhko O.V., Ublinzkiy M.V. — approval of the final version of the article.
