The role of the intact hemisphere in the rehabilitation process after IS remains a controversial subject. The hypothesis for the investigation is that the development of a diffusion and perfusion model (DPM) based on the assessment of FA in combination with data on cerebral blood flow velocity (CBFV) and the impact of the focus will be able to predict the patients' neurological status by the end of the acute period of IS. </p><sec><title>Objective</title><p>Objective: to investigate the role of diffusion and perfusion characteristics of the intact hemisphere in determining the rehabilitation potential in the acute period of IS and to develop a prognostic DPM.</p></sec><sec><title>Patients and methods</title><p>Patients and methods. The investigation enrolled 100 patients with IS and 10 individuals in the control group. All the examinees underwent brain MRI. Perfusion-weighted sequence without bolus injection of a contrast agent was used to quantify CBFV in 10 areas according to the Alberta stroke program early CT score (ASPECTS). Values for FA in 10 areas of both hemispheres were calculated using DTI findings. Neurological and functional statuses were evaluated over time with the National Institute of Health Stroke Scale (NIHSS) and the modified Rankin scale.</p></sec><sec><title>Results</title><p>Results. The NIHSS score at discharge was associated with FA and CBFV in 4 and 6 of the 10 areas of the intact hemisphere, respectively. DPM for predicting the rehabilitation potential included the key parameters correlating with a discharge NIHSS score (in order of decreasing the significance): admission NIHSS value (r = 0.55; p &lt; 0.001), the size of a focus (r = 0.42; p &lt; 0.001), FA in the contralateral cingulum bundle FA (r = -0.28; p = 0.007), and CBFV in M2 white matter [r = -0.24; p = 0.025; R2 = 0.642; p(F) &lt;0.001].</p></sec><sec><title>Conclusion</title><p>Conclusion. In addition to the NIHSS score at admission, the size of a focus, DPM values (FA in the contralateral cingulum bundle and CBFV in the white matter) allow prediction of the rehabilitation potential in IS.</p></sec></abstract><trans-abstract xml:lang="ru"><p>К числу перспективных подходов к определению реабилитационного потенциала пациентов, перенесших ишемический инсульт (ИИ), относится оценка микроструктурной целостности вещества мозга методом диффузионно-тензорной магнитно-резонансной томографии (МРТ; Diffusion Tensor Imaging, DTI), основным показателем которой служит фракционная анизотропия (ФА). Роль интактного полушария в процессе реабилитации после ИИ остается предметом споров. Гипотеза исследования заключается в том, что создание диффузионно-перфузионной модели (ДПМ), основанной на оценке ФА в комплексе с данными о скорости мозгового кровотока (СМК) и влиянии очага, позволит прогнозировать неврологический статус пациентов к концу острого периода ИИ.</p><p>Цель исследования – изучение роли диффузионно-перфузионных характеристик интактного полушария в определении реабилитационного потенциала в остром периоде ИИ и построение прогностической ДПМ.</p><sec><title>Пациенты и методы</title><p>Пациенты и методы. В исследование включено 100 пациентов с ИИ и 10 лиц группы контроля. Всем участникам исследования проводили МРТ головного мозга. При помощи перфузионно-взвешенной последовательности без болюсного введения контрастного препарата количественно оценивали СМК в 10 зонах по шкале ASPECTS. По данным DTI вычисляли значения ФА в 10 зонах обоих полушарий. Неврологический и функциональный статус оценивали в динамике по шкале инсульта Национального института здоровья (National Institutes of Health Stroke Scale, NIHSS) и модифицированной шкале Рэнкина.</p></sec><sec><title>Результаты</title><p>Результаты. Результат NIHSS при выписке ассоциирован с ФА в 4 зонах и СМК в 6 зонах из 10 интактного полушария. В ДПМ прогнозирования реабилитационного потенциала вошли следующие ключевые параметры, коррелирующие с показателем NIHSS при выписке (в порядке уменьшения значимости): показатель NIHSS при поступлении (r=0,55; p&lt;0,001), размер очага (r=0,42; p&lt;0,001), ФА контралатерального поясного пучка (r=-0,28; p=0,007) и СМК в белом веществе М2 [r=-0,24; p=0,025; R2=0,642; p(F)&lt;0,001].</p></sec><sec><title>Заключение</title><p>Заключение. Кроме показателя NIHSS при поступлении и размера очага, значения ДПМ (ФА контралатерального поясного пучка, СМК в белом веществе) позволяют прогнозировать реабилитационный потенциал при ИИ.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>диффузионно-тензорная томография</kwd><kwd>фракционная анизотропия</kwd><kwd>ASL-перфузия</kwd><kwd>скорость мозгового кровотока</kwd><kwd>ишемический инсульт</kwd><kwd>реабилитационный потенциал</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diffusion tensor imaging</kwd><kwd>fractional anisotropy</kwd><kwd>arterial spin labeling (ASL) perfusion</kwd><kwd>cerebral blood flow velocity</kwd><kwd>ischemic stroke</kwd><kwd>rehabilitation potential</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">Veerbeek JM, Kwakkel G, van Wegen EE, et al.
