The study included 11 patients with AD (five women and six men; mean age 75.3±9.4 years; MoCA score 11.2±3.9) and 12 volunteers without cognitive impairment (eight women and four men; mean age 72.7±8.9 years; MoCA score 26.7±0.9). QSM MRI was performed on a Signa PET/MR 3.0 T tomograph using a 32-channel coil. In both hemispheres, the regions studied included the amygdala, caudate nucleus, putamen, hippocampus, globus pallidus, thalamus, frontal, temporal, parietal and occipital lobes, and posterior cingulate gyrus. For each region, volume (voxels), QSM (ppm), and QSM/volume ratio were calculated.</p></sec><sec><title>Results</title><p>Results. In patients with AD, QSM and QSM/volume values were higher and volume was lower than in the control group in most areas. The left temporal lobe cortex (volume, QSM and QSM/volume – SE ≥93.7, SP ≥90.4, AUC ≥0.921; p&lt;0.0001), the hippocampus (volume and QSM/volume – SE ≥91.9, SP ≥89.1, AUC ≥0.939; p&lt;0.0001) and the amygdala (volume – SE ≥88.4, SP ≥91.6, AUC ≥0.902; p&lt;0.0001) of both hemispheres had the highest sensitivity and specificity. In the hippocampi and amygdalae, the QSM/volume ratio had greater sensitivity and specificity than QSM (ΔAUC ≥0.277±0.105, z≥2.636; p≤0.0084). There was a correlation between the total MoCA score and the volume of the amygdala, hippocampus, and temporal lobe cortex of the left hemisphere (r≥0.429; p≤0.0026). In addition, there was a relationship between the total MoCA score and QSM in the caudate nuclei and putamen of both hemispheres, in the left temporal lobe (r≥-0.429; p≤0.019) and QSM/volume in the caudate nuclei and hippocampi of both hemispheres, in the putamen and temporal lobe of the left hemisphere (r≥-0.415; p≤0.014).</p></sec><sec><title>Conclusion</title><p>Conclusion. This study demonstrated a correlation between QSM, the QSM/volume ratio, morphometric parameters, and the total MoCA score in AD. The QSM/volume ratio has greater sensitivity and specificity than QSM in distinguishing between the AD group and the control group.</p></sec></abstract><trans-abstract xml:lang="ru"><p>Цель исследования – изучить изменение количественного картирования восприимчивости (QSM) магнитно-резонансной томографии (МРТ) головного мозга (ГМ) у пациентов с болезнью Альцгеймера (БА) и сопоставить с результатами морфометрического исследования и состоянием когнитивных функций.</p><sec><title>Материал и методы</title><p>Материал и методы. В исследование включено 11 пациентов с БА (пять женщин и шесть мужчин; средний возраст – 75,3±9,4 го- да; оценка по MoCA – 11,2±3,9) и 12 добровольцев без когнитивных нарушений (восемь женщин и четыре мужчины; средний воз- раст – 72,7±8,9 года; оценка по MoCA – 26,7±0,9). QSM МРТ проводилась на томографе Signa PET/MR 3,0 T с использованием 32-канальной катушки. В обоих полушариях изучаемые области включали миндалевидное тело, хвостатое ядро, скорлупу, гиппокамп, бледный шар, зрительный бугор, лобные, височные, теменные и затылочные доли и заднюю поясную извилину. Для каждой области были рассчитаны объем (воксели), QSM (ppm) и отношениеQSM/объем.</p></sec><sec><title>Результаты</title><p>Результаты. У пациентов с БА в большинстве областей значения QSM и QSM/объем были больше, а объем – меньше, чем в контрольной группе. Наибольшей чувствительностью и специфичностью обладали кора левой височной доли (объем, QSM и QSM/объем – SE ≥93,7, SP ≥90,4, AUC ≥0,921; p&lt;0,0001), гиппокампы (объем и QSM/объем – SE ≥91,9, SP ≥89,1, AUC ≥0,939; p&lt;0,0001) и миндалевидные тела (объем – SE ≥88,4, SP ≥91,6, AUC ≥0,902; p&lt;0,0001) обоих полушарий. В гиппокампах и миндалевидных телах отношение QSM/объем обладало большей чувствительностью и специфичностью, чем QSM (ΔAUC ≥0,277±0,105, z≥2,636; p≤0,0084). Наблюдалась корреляция между общим баллом по шкале MoCA и объемом миндалевидного тела, гиппокампа и коры височной доли левого полушария (r≥0,429; p≤0,0026). Кроме того, имелась связь между общим баллом по шкале MoCA и QSM в хвостатых ядрах и скорлупе обоих полушарий, в левой височной доле (r≥-0,429; p≤0,019) и QSM/объем в хвостатых ядрах и гиппокампах обоих полушарий, в скорлупе и височной доле левого полушария (r≥-0,415; p≤0,014).</p></sec><sec><title>Заключение</title><p>Заключение. Настоящее исследование показало связь между QSM, соотношением QSM/объем, морфометрическими показателями и общим баллом по шкале MoCA при БА. Отношение QSM/объем обладает большей чувствительностью и специфичностью, чем QSM, в разграничении группы БА и контрольной группы.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>болезнь Альцгеймера</kwd><kwd>нейродегенерация</kwd><kwd>деменция</kwd><kwd>когнитивная дисфункция</kwd><kwd>MoCA</kwd><kwd>атрофия</kwd><kwd>морфометрия</kwd><kwd>количественное картирование восприимчивости</kwd><kwd>МРТ</kwd><kwd>QSM МРТ</kwd><kwd>железо</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Alzheimer's disease</kwd><kwd>neurodegeneration</kwd><kwd>dementia</kwd><kwd>cognitive dysfunction</kwd><kwd>MoCA</kwd><kwd>atrophy</kwd><kwd>morphometry</kwd><kwd>quantitative susceptibility mapping</kwd><kwd>MRI</kwd><kwd>QSM MRI</kwd><kwd>iron</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">Ayton S, Portbury S, Kalinowski P, et al.
