Материалом исследования являлись изображения динамической контрастной МРТ органов брюшной полости с метастатическим поражением печени. Параметры преднасыщающего импульса: Δf = −210 Гц, FA = 600°. Для каждого очага рассчитывали коэффициент контраста (КК) по формуле: КК = ((Iочаг − Iпечень) / Iпечень) • 100%. Васкуляризацию оценивали по шкале из трех категорий: гиповаскулярный, изоваскулярный и гиперваскулярный. Пороговые значения каждой категории рассчитывали с помощью кластерного анализа. Для оценки чувствительности выявления очаги были разделены на группы по размеру: 1-я − от 5 до 10 мм; 2-я – от 10 до 20 мм. Статистическую обработку результатов выполняли при помощи критериев Манна−Уитни, Вилкоксона, Кохрена и Мак-Немара.</p></sec><sec><title>Результаты</title><p>Результаты. В ходе клинического исследования получены неоднородные по полу и возрасту группы пациентов в зависимости от характера васкуляризации очагов в печени при анализе артериальной фазы динамического контрастного усиления (ДКУ): гиперваскулярные (n = 14) и гиповаскулярные (n = 38), которым суммарно выполнено 52 исследования, так как у одного пациента был динамический контроль. Выявлено пороговое значение для группы гиперваскулярных метастазов: КК &gt; 49,6%. В 1-й группе (от 5 до 10 мм) чувствительность выявления очагов на постконтрастных изображениях T-TSE-MTC составила 47,7%. Во 2-й группе диагностика очагов размером от 10 мм и более между постконтрастными изображениями Т1-TSE-MTC и всеми фазами ДКУ статистически значимых различий не выявила (р &lt; 0,0001), а чувствительность составила 100%.</p></sec><sec><title>Выводы</title><p>Выводы. 1. По данным кластерного анализа Т1-взвешенное исследование на основе быстрого спинового эха с эффектом переноса намагниченности (T1-TSE-MTC) позволяет дифференцировать гиперваскулярные метастазы от переходных и гиповаскулярных (p &lt; 0,05).</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: To evaluate the diagnostic capabilities of detecting metastatic lesions on post-contrast images using magnetization transfer contrast with a short fat-suppressed presaturation pulse.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study material consisted of dynamic contrast-enhanced MR images of abdominal organs with metastatic liver involvement. Parameters of the pre-saturation pulse: Δf = -210 Hz, FA = 600°. Contrast ratio (CR) was calculated for each focus using a formula: CR = ((IFOCUS – ILIVER) / ILIVER) • 100%. Vascularization was assessed on a scale of 3 categories: hypovascular, isovascular, and hypervascular. Threshold values for each category were calculated using cluster analysis. To assess the sensitivity of focus detection, they were divided into groups by size: Group 1 − from 5 mm to 10 mm; Group 2 − from 10 mm to 20 mm. Statistical analysis of the results was performed using the Mann-Whitney, Wilcoxon, Cochran, and McNemar criteria.</p></sec><sec><title>Results</title><p>Results. In the course of the clinical study, heterogeneous groups of patients were obtained in terms of gender and age depending on the nature of vascularization of liver foci during analysis of the arterial phase of DCE: hypervascular (n = 14) and hypovascular (n = 38), with a total of 52 studies conducted, as one patient had dynamic control. The threshold value for the group of hypervascular metastases was identified as CR &gt; 49.6%. In Group 1 (5 mm to 10 mm), the sensitivity of detecting foci on post-contrast images T-TSE-MTC was 47.7%. In Group 2, there were no statistically significant differences between the diagnosis of foci sized 10 mm or larger on post-contrast images T1-TSE-MTC and all phases of DCE (p &lt; 0.0001), with a sensitivity of 100%.</p></sec><sec><title>Conclusions</title><p>Conclusions. 1. According to cluster analysis, T1-weighted study based on fast spin echo with magnetization transfer contrast (T1-TSE-MTC) allows differentiation of hypervascular metastases from transitional and hypovascular (p &lt; 0.05).</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>печень</kwd><kwd>метастазы</kwd><kwd>МРТ</kwd><kwd>перенос намагниченности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>liver</kwd><kwd>metastases</kwd><kwd>MRI</kwd><kwd>magnetization transfer</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">Ломовцева К.Х., Кармазановский Г.Г.
