Выявлена взаимосвязь таких показателей, как фракционная анизотропия (ФА), измеряемый коэффициент диффузии (ИКД), объем инфаркта мозга и степень двигательного дефицита. Полученные закономерности при измерении ФА и ИКД в областях проекции кортикоспинального тракта (КСТ) позволяют считать их показателями степени постишемического поражения КСТ, предопределяющими двигательный дефицит. Установлено, что ФА является наиболее надежным показателем структурной целостности КСТ. Определены пороговые значения ФА (индекс, %) для неблагоприятного исхода двигательного восстановления: заднее бедро внутренней капсулы – 50%, ножка мозга – 42%, варолиев мост – 65%. Высокая чувствительность и специфичность полученных данных позволяет использовать их для выделения групп больных, чье дальнейшее двигательное улучшение резко ограничено.</p></trans-abstract><kwd-group xml:lang="en"><kwd>ischemic stroke</kwd><kwd>motor recovery</kwd><kwd>fractional anisotropy</kwd><kwd>apparent diffusion coefficient</kwd><kwd>infarction volume</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>ишемический инсульт</kwd><kwd>двигательное восстановление</kwd><kwd>фракционная анизотропия</kwd><kwd>измеряемый коэффициент диффузии</kwd><kwd>объем инфаркта</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Кадыков А.С.
