Диффузионно-тензорная МРТ и протокол susceptibility-weightedimaging (SWI) — современные неинвазивные нейровизуализационные методики, которые при совместном применении у пациентов с БП позволяют не только оценить распределение и патологическое отложение железа в базальных ганглиях, но и его вероятное влияние на дисфункцию структур экстрапирамидной системы.</p><p>Цель исследования — определить количественное содержание железа в базальных ганглиях у пациентов с II и III стадией болезни Паркинсона и оценить его влияние на дисфункцию компонентов экстрапирамидной системы.</p><sec><title>Материал и методы</title><p>Материал и методы. Обследовано 67 пациентов со БП с II (32 больных) и III (35 больных) стадиями по Хен/ Яру. Всем пациентам выполнялось сканирование головного мозга на высокопольном МР-томографе SiemensTrioTim (3Т) с применением импульсной последовательности SWI и диффузионно-тензорной МРТ. Количественная оценка степени депонирования железа проводилась при помощи программного обеспечения SPINsoftware в областях интереса с обеих сторон: зубчатое ядро мозжечка (ЗЯ), черная субстанция (ЧС), красное ядро (КЯ), скорлупа, бледный шар (БШ), головка хвостатого ядра (ХЯ). Также в проекции исследуемых зон проводился расчет уровня фракционной анизотропии (ФА).</p></sec><sec><title>Результаты</title><p>Результаты. Обнаружены статистически достоверные более низкие показатели ФА в левом БШ и правом КЯ у пациентов с III стадией БП в сравнении с пациентами со II стадией по Хен/Яру. У больных со II стадией были выявлены положительные корреляции между уровнем ФА в левой скорлупе и степенью гипоинтенсивности сигнала от ЧС, БШ, КЯ (все с обеих сторон) и правого ХЯ. Уровень ФА в правой скорлупе коррелировал с степенью гипоинтенсивности сигнала от левой ЧС. Значение ФА в левом КЯ имело корреляции с гипоинтенсивностью сигнала от ЧС, БШ (все с обеих сторон), правого КЯ, левой скорлупы, правого ХЯ. У пациентов с III стадией по Хен/Яру обнаружены единственные достоверные положительные корреляционные связи между уровнем ФА и гипоинтенсивностью сигнала от исследуемых зон: левое ХЯ и левая скорлупа, правая скорлупа и левое ХЯ, левая ЧС и правое ХЯ соответственно. Значения гипоинтенсивности сигнала от левого КЯ, правой скорлупы, левого ХЯ и правого БШ положительно коррелировали с показателем ФА в правой ЧС. Снижение ФА в внутреннем сегменте левого БШ коррелировало с уровнем гипоинтенсивности сигнала от правого ЗЯ и правого КЯ.</p></sec><sec><title>Заключение</title><p>Заключение. Депонирование железа в базальных ганглиях при БП вносит значительный вклад в прогрессирование заболевания и оказывает влияние на формирование большинства двигательных проявлений пациентов. Динамическая неинвазивная оценка степени накопления исследуемого металла в компонентах экстрапирамидной системы позволит более тщательно отслеживать ход течения нейродегенеративного процесса и формировать группы наблюдения по риску возникновения осложнений БП.</p></sec></abstract><trans-abstract xml:lang="en"><p>Parkinson’s disease (PD) is a chronic, steadily progressing disease of the central nervous system (CNS) that belongs to the group of synucleinopathies, which causes significant damage to the health of the elderly and leads to disability in the process of progression. Diffusion-tensor MRI and the susceptibility-weighted imaging (SWI) protocol are modern non-invasive neuroimaging techniques that, when used together with patients with PD, can not only assess the distribution and pathological deposition of iron in the basal ganglia, but also its likely effect on the dysfunction of extrapyramidal system structures.</p><sec><title>Goal</title><p>Goal. To determine the quantitative content of iron in the basal ganglia in patients with stage II and III (H/Y) Parkinson ’s disease and evaluate its effect on the dysfunction of the components of the extrapyramidal system.</p></sec><sec><title>Material and methods</title><p>Material and methods. We examined 67patients with PD with II (n = 32) andIII (n = 35) Hoehn/Yahr (H/Y) stages. To everyone was performed a brain scan on a Siemens TrioTim high-field MRI scanner (3T) using the pulse sequence SWI and diffusion-tensor MRI. A quantitative assessment of the degree of iron deposition was carried out using SPIN software in regions of interest (ROIs) on both sides: the dentate nucleus (DN), the substantia nigra (SN), the red nucleus (RN), the putamen (PUT), the globus pallidusm (GP), the head of the caudate nucleus (CN). Also, in the projection of ROIs, the fractional anisotropy (FA) values was calculated.</p></sec><sec><title>Results</title><p>Results. Significant (p &lt;0,05) lower FA values were found in left GP and right RN in patients with stage III (H/Y) in comparison with patients with stage II (H/Y). In patients with stage II (H/Y), significant positive correlations were found between the FA values in the left PUT and the hypointensity of SN, GP, RN (all on both sides) and right CN. The FA value in the right PUT correlated with hypointensity of the left SN. The FA value in the left RN had correlations with the hypointensity of the SN, GP (all on both sides), the right RN, the left PUT, and the right CN. In patients with stage III (H/Y), the only reliable positive correlations were found between the FA values and the hypointensity of the ROIs: left CN and left PUT, right PUT and left CN, left SN and right CN, respectively. SWI hypointensity of the left RN, the right PUT, the left CN, and the right GP correlated positively with the FA value in the right SN. The decrease FA value in the left internal GP correlated with the hypointensity of the right DN and right RN.</p></sec><sec><title>Conclusion</title><p>Conclusion. The deposition of iron in the basal ganglia in PD makes a significant contribution to the progression of the disease and affects the formation of most motor manifestations in this category of patients. A dynamic non-invasive assessment of the degree of iron accumulation in the components of the extrapyramidal system will more closely monitor the course of the neurodegenerative process and form observation groups for the risk of PD complications.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>болезнь Паркинсона</kwd><kwd>изображения</kwd><kwd>взвешенные по магнитной восприимчивости</kwd><kwd>депонирование железа</kwd><kwd>биомаркер</kwd><kwd>магнитно-резонансная томография</kwd><kwd>диффузионно-тензорные изображения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Parkinson’s disease</kwd><kwd>susceptibility-weighted imaging (SWI)</kwd><kwd>iron deposition</kwd><kwd>biomarker</kwd><kwd>magnetic resonance imaging</kwd><kwd>diffusion-tensor imaging (DTI)</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">Левин О.С., Федорова Н.В.
