Обследовано 58 человек в возрасте 50–79 лет: 45 пациентов с диагнозом “хроническая недостаточность мозгового кровообращения” (ХНМК) и 13 условно здоровых добровольцев. Пациенты с ХНМК были ранжированы на 3 группы в зависимости от тяжести когнитивных расстройств (КР). МР-протокол (Toshiba “Vantage Titan”, 1,5 Тл) включал: Т1-, Т2-, T2*-ВИ, DWI, FLAIR и бесконтрастную МР-перфузию (ASL – Arterial Spin Labeling). Анализ МР-паттернов ХНМК проводился по критериям STRIVE. По данным ASL-перфузии оценивался общий церебральный кровоток и регионарный в лобных и теменных долях.</p></sec><sec><title>Результаты</title><p>Результаты. Выявлена зависимость между степенью лейкоареоза, типом расширения периваскулярных пространств Вирхова–Робина и уровнем КР. По данным ASL общий церебральный кровоток выше в группах без КР и у пациентов с выраженными КР. У пациентов с легкими КР – диффузное снижение церебральной перфузии. Данный феномен объясняется начальными нарушениями проницаемости гематоэнцефалического барьера, повреждением микроциркуляторного русла. Относительная гиперперфузия в коре лобных и теменных долей пациентов с деменцией свидетельствует о неэффективности усиления коркового кровотока и сформировавшемся шунтирующем кровотоке из-за высокого сопротивления измененных мел- ких церебральных сосудов в условиях высоких пульсативных свойств магистральных артерий.</p></sec><sec><title>Заключение</title><p>Заключение. ASL-перфузия – дополняющее звено к критериям STRIVE в диагностике ХНМК. Отсутствие изменения церебральной перфузии у пациентов с субъективными проявлениями ХНМК обусловливает целесообразность поиска новых методов диагностики доклинических стадий сосудистых когнитивных расстройств.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To evaluate the neuroimaging patterns of chronic cerebrovascular insufficiency with cerebral perfusion assessment depending on the level of cognitive impairment.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The 58 patients aged 50–79 years were examined: 45 patients with a diagnosis of сhronic cerebrovascular insufficiency and 13 conditionally healthy volunteers. Patients with Chronic cerebrovascular insufficiency were ranked into three subgroups depending on the severity of cognitive impartment (CI). T1-, T2, T2*- VI, DWI, FLAIR and non-contrast MR perfusion (ASL) were included in the MR-protocol (Toshiba Vantage Titan, 1.5 T). The analysis of MRM patterns of Chronic cerebrovascular insufficiency was carried out according to STRIVE criteria. The total cerebral blood flow and regional in the frontal and parietal lobes were evaluated by the ASLperfusion.</p></sec><sec><title>Results</title><p>Results. A relationship was found between the degree of leukoaraiosis, the type of expansion of the perivascular spaces of Virchow-Robin and the level of CI. According to ASL, total cerebral blood flow is higher in groups without CI and in patients with severe CI. There is a diffuse decrease of cerebral perfusion in patients with mild CI. This phenomenon is explained by initial impairment of the blood-brain barrier permeability, damage to the microvasculature. Relative hyperperfusion in the cortex of the frontal and parietal lobes of patients with dementia indicates the ineffectiveness of increased cortical blood flow and the resulting shunt blood flow due to the high resistance of the altered small cerebral vessels under high pulsating properties of the main arteries.</p></sec><sec><title>Conclusion</title><p>Conclusion. ASL perfusion is a complementary link to the STRIVE criteria in the diagnosis of chronic cerebrovascular insufficiency. The absence of changes in cerebral perfusion in patients with subjective manifestations of chronic cerebrovascular insufficiency makes it advisable to search for new methods for the diagnosis of preclinical stages of vascular cognitive impairment.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>скорость церебрального кровотока</kwd><kwd>ASL-перфузия головного мозга</kwd><kwd>бесконтрастная МР-перфузия</kwd><kwd>хроническая недостаточность мозгового кровообращения</kwd><kwd>болезнь малых церебральных сосудов</kwd><kwd>когнитивные расстройства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cerebral blood flow</kwd><kwd>ASL-perfusion of the brain</kwd><kwd>non-contrast MR-perfusion</kwd><kwd>chronic cerebrovascular insufficiency</kwd><kwd>small vessel disease</kwd><kwd>cognitive impairment</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">Гудкова В.В., Стаховская Л.В.
