Одной из самых перспективных тенденций современных исследований является оценка перфузионных изменений головного мозга при диагностике ишемического инсульта (ИИ). Цель исследования – провести комплексную динамическую оценку перфузионных изменений головного мозга у пациентов в раннем постинсультном восстановительном периоде и условно-здоровых добровольцев методом ASL. Материал и методы. Осуществлено проспективное наблюдение двух групп исследуемых; в группу контроля вошли 20 условно здоровых добровольцев в возрасте от 18 до 25 лет (21,8 ± 2,6 года) (среднее арифметическое ± стандартное отклонение), в группу патологии – 20 человек с верифицированным ИИ в возрасте от 40 до 70 лет (59,4 ± 9,2 года) на 1–3-и, 7–10-е сутки и спустя 3 месяца после манифестации заболевания. Интегрально оценены показатели перфузии серого и белого вещества долей больших полушарий головного мозга (теменная, затылочная, лобная, височная), рассчитаны значения перфузии в ипси- и контралатеральных относительно очага инсульта областях интереса. Результаты и их обсуждение. У пациентов с ИИ очаг инсульта имеет нелинейную динамику изменений перфузии с 19,86 ± 5,69 мл/100 г/мин на 1–3-и сутки, повышением показателя до 27,57 ± 4,86 мл/100 г/мин на 7–10-е сутки и уменьшением до 14,48 ± 3,66 мл/100 г/мин к 3–4-му месяцу, оставаясь в пределах низких значений по сравнению с визуально-интактными областями и контрольной группой. Перфузия в визуально-интактной области ипсилатерального по отношению к очагу инсульта полушария на 1–3-и и 7–10-е сутки статистически значимо (p &lt; 0,05) снижена по сравнению с другими областями интереса на 4–5 %. При этом наблюдается плавное нарастание значений перфузии во всех анализируемых объемных областях от первого исследования к третьему. Заключение. Методика ASL позволяет количественно оценивать динамику церебральной перфузии раннего восстановительного периода с регистрацией статистически значимого снижения (p &lt; 0,001) тканевого кровотока в очаге ишемии относительно анализируемых областей интереса головного мозга и контрольной группы. Интактная область в ипсилатеральном по отношению к очагу инсульта полушарии имеет плавную динамику роста от гипоперфузии к нормоперфузии, что связано с вовлечением мозга как органа в целом и постепенным восстановлением его перфузионной характеристики.</p></abstract><trans-abstract xml:lang="en"><p>Arterial spin labeling (ASL) allows the assessment of tissue perfusion and has advantages such as non-invasiveness and the ability to repeat examinations multiple times. This enables dynamic monitoring without contrast administration. This technique requires additional pre- and post-processing, complicating result acquisition. A promising trend is the assessment of brain perfusion changes for diagnosing ischemic stroke. Aim of the study was to evaluate a comprehensive dynamic perfusion change in the brain in patients in the early post-stroke recovery period and conditionally healthy volunteers by the ASL. Material and Methods. A prospective observation of two groups was performed. The control group included 20 conditionally healthy volunteers aged from 18 to 25 years (21.8 ± 2.65 years) (mean ± standard error of the mean), the study group ‒ 20 patients with verified ischemic stroke aged from 40 to 70 years (59.4 ± 9.2 years) on days 1–3, 7–10, and three months after disease onset. Perfusion indicators of gray and white matter of the lobes of the cerebral hemispheres (parietal, occipital, frontal, temporal) in visually intact areas of the brain were integrally evaluated. Perfusion values were also calculated in ipsilateral and contralateral regions of interest relative to the stroke focus. Results and discussion. The stroke focus shows a nonlinear dynamic of changes, starting from 19.86 ± 5.69 ml/100 g/ min on days 1–3, increasing to 27.57 ± 4.86 ml/100 g/min on days 7–10, and decreasing to 14.48 ± 3.66 ml/100 g/min by the 3–4 month, remaining low compared to visually intact areas and the control group. Perfusion in the visually intact area of the ipsilateral hemisphere in relation to the stroke focus is significantly (p &lt; 0.05) reduced by 4–5 % on days 1–3 and 7–10 compared to other regions of interest. Meanwhile, there is a gradual increase in perfusion values in all analyzed regions from the first to the third examination. Conclusions. The ASL method allows for the quantitative assessment of the dynamics of cerebral perfusion in the early recovery period, with a significant (p &lt; 0.001) reduction in tissue blood flow in the ischemic focus relative to the analyzed regions of interest and the control group. The intact area in the ipsilateral hemisphere in relation to the stroke focus shows dynamic growth from hypoperfusion to normoperfusion, which is related to the involvement of the brain as a whole organ.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ишемический инсульт</kwd><kwd>бесконтрастная перфузия</kwd><kwd>ASL</kwd><kwd>pCASL</kwd><kwd>CBF</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ischemic stroke</kwd><kwd>contrast-free perfusion</kwd><kwd>ASL</kwd><kwd>pCASL</kwd><kwd>CBF</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено при поддержке Минобрнауки России (гос. задание: 1023110800234-5-3.2.25;3.1.4;3.2.12, «Изучение процессов постинсультной структурно-функциональной реорганизации головного мозга современными методами нейровизуализации»).</funding-statement><funding-statement xml:lang="en">The study was supported by Ministry of Education and Science of Russia (1023110800234-5-3.2.25;3.1.4;3.2.12, “Studying the processes of post-stroke structural and functional reorganization of the brain using modern neuroimaging methods”).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Alsop D., Detre J., Golay X., Günther M., Hendrikse J., Hernandez-Garcia L., Lu H., MacIntosh B., Parkes L., Smits M., … Zaharchuk G.
