Материал и методы. Измерены показатели фракционной анизотропии 10 зон белого и серого вещества головного мозга у 30 пациентов в остром периоде ишемического инсульта методом диффузионно-тензорного изображения. Оценены показатели неврологического (NIHSS), когнитивного (MMSE), функционального статусов (индекс мобильности Ривермид и модифицированная шкала Ренкина), а также лабораторно-инструментальные данные. Результаты. Проанализированы различия фракционной анизотропии на стороне очага поражения и симметричных участках головного мозга. Выявлено снижение показателя в зоне задней ножки внутренней капсулы на стороне очага по сравнению с симметричными зонами интактного полушария вне зависимости от расположения зоны инфаркта. Продемонстрирована взаимосвязь между значениями фракционной анизотропии в исследованных зонах со степенью неврологического дефицита и когнитивным статусом при выписке, а также длительностью лечения. Заключение. Проведенное исследование может свидетельствовать о том, что уже в остром периоде ишемического инсульта параллельно инициируются процессы нейродегенерации и нейрорепарации, проявляющиеся изменением интегральности белого и серого вещества головного мозга. В подтверждение концепции “сердце-сосуды-мозг” получены данные о значимости сосудистых факторов риска, обусловливающих гипоперфузию и гипоксию, в развитии микроструктурных изменений изученных зон мозга. Ряд показателей фракционной анизотропии, рассмотренных в работе, могут служить предикторами неврологического и функционального исхода при выписке пациентов из стационара.</p></abstract><trans-abstract xml:lang="en"><p>Aim. To study the fractional anisotropy of white and gray brain matter and its associations with clinical and instrumental data in acute ischemic stroke. Materials and methods. The parameters of fractional anisotropy of 10 areas of white and gray brain matter were analyzed in 30 acute ischemic stroke patients by diffusion-tensor imaging. The neurological (NIHSS), cognitive (MMSE), functional (Rivermead Mobility Index and Modified Rankin Scale) and some laboratory and instrumental data were assessed. Results. The fraction anisotropy was analyzed on the side of lesion and symmetrically. The decline of anisotropy was revealed in posterior limb of internal capsule on the side of stroke independently of the lesion location. Also the interactions between fraction anisotropy and stroke severity, global cognitive status and duration of hospital treatment were found. Conclusion. The obtained data may suggest that in acute period of stroke the neurodegeneration and neuroreparational ready start. It appears the changes of white and gray matter integrity. According to the concept “heart-vessels-brain” we received the data indicating the significance of vascular risk factors which lead to hypoperfusion and hypoxia in the development of microstructural changes. Some parameters of fractional anisotropy may predict clinical and functional outcome on discharge.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фракционная анизотропия</kwd><kwd>ишемический инсульт</kwd><kwd>трактография</kwd><kwd>внутренняя капсула</kwd><kwd>fractional anisotropy</kwd><kwd>ischemic stroke</kwd><kwd>tractography</kwd><kwd>internal capsule</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">Chen J.L., Schlaug G.
