Разработка отечественного препарата для ультразвуковых исследований с контрастным усилением позволит не только повысить доступность подобных исследований, но и значительно расширить область их применения. Цель исследования – сравнить геометрические характеристики, визуализационные и кинетические свойства прототипа отечественного ультразвукового контрастного вещества с препаратом Соновью (Bracco Swiss SA) в условиях фантомного моделирования сосудистых структур. Материалы и методы. В процессе исследования применялись два ультразвуковых контрастных вещества: прототип ультразвукового контрастного вещества – суспензия микропузырьков с белковой оболочкой (альбумин/глюкоза), наполненных 1,1,1,2-тетрафторэтаном; Соновью – микропузырьки гексафторида серы с фосфолипидной оболочкой. Геометрия микропузырьков оценивалась с помощью оптической микроскопии (МИКМЕД-6), рассчитывался коэффициент полидисперсности (D10/D50/D90). Визуализация выполнялась на системе Sonoscape S50 Elite (В-режим и режим контраст) с использованием обучающего фантома воротной вены и «клубка» капилляров; механический индекс 0,12–0,15, частота 9,0–10,8 МГц. Результаты. Средний диаметр микропузырьков Соновью составил ~2,5 мкм (полидисперсность ~1,1); прототипа – ~1,9 мкм (полидисперсность ~0,8). На модели воротной вены оба препарата обеспечили выраженное контрастное усиление; отличие – кинетика: время до пика сигнала ~40 с для Соновью и ≤10 с для прототипа с более быстрым «вымыванием» в ROI. На модели «клубка» капилляров отмечены снижение полосовых артефактов при использовании прототипа и более чистая визуализация поперечных срезов капилляров. Выводы. Прототип ультразвукового контрастного вещества продемонстрировал сопоставимое контрастное усиление с иным профилем фармакокинетики и меньшей выраженностью некоторых артефактов в условиях фантома. Различия, вероятно, обусловлены газом-наполнителем и составом оболочки микропузырьков. Полученные данные поддерживают перспективность дальнейшей доработки и доклинической валидации прототипа.</p></abstract><abstract xml:lang="en" abstract-type="summary"><p>Contrast-enhanced ultrasound using ultrasound contrast agents is an effective diagnostic method that improves visualization and detail of organs and tissues being examined, offering several advantages over alternative methods. The development of a domestically produced contrast-enhanced ultrasound product will not only increase the availability of such examinations but also significantly expand their scope of application. The aim of the study was to compare the geometric characteristics, visualization and kinetic properties of a prototype of a domestic ultrasound contrast agent with the drug Sonovu (Bracco Swiss SA) under conditions of phantom modeling of vascular structures. Materials and methods. Two ultrasound contrast agents were used in the study: a prototype ultrasound contrast agent – a suspension of microbubbles with a protein shell (albumin/glucose) filled with 1,1,1,2-tetrafluoroethane; Sonovue – sulfur hexafluoride microbubbles with a phospholipid shell. Microbubble geometry was assessed by optical microscopy (MICMED-6) with calculation of the polydispersity coefficient (D10/D50/D90). Visualization was performed on a Sonoscape S50 Elite system (B-mode and contrast mode) using a training phantom of the portal vein and a capillary "tangle"; mechanical index 0.12–0.15, frequency 9.0–10.8 MHz. Results. The average microbubble diameter of Sonovue was ~2.5 µm (polydispersity ~1.1); that of the prototype was ~1.9 µm (polydispersity ~0.8). In the portal vein model, both preparations provided significant contrast enhancement; the difference was in the kinetics: the time to signal peak was ~40 s for Sonovue and ≤10 s for the prototype, with faster washout in the ROI. In the capillary tangle model, reduced banding artifacts were observed with the prototype, along with clearer visualization of capillary cross-sections. Conclusions. A prototype ultrasound contrast agent demonstrated comparable contrast enhancement with a different pharmacokinetic profile and reduced severity of some artifacts in a phantom environment. These differences are likely due to the filler gas and the composition of the microbubble shell. These data support the potential for further development and preclinical validation of the prototype.</p></abstract><kwd-group xml:lang="ru"><kwd>контраст-усиленное ультразвуковое исследование</kwd><kwd>ультразвуковое контрастное вещество</kwd><kwd>микропузырьки</kwd><kwd>Sonovue</kwd><kwd>тетрафторэтан</kwd><kwd>фантом</kwd></kwd-group><kwd-group xml:lang="en"><kwd>contrast-enhanced ultrasound</kwd><kwd>ultrasound contrast agent</kwd><kwd>microbubbles</kwd><kwd>Sonovue</kwd><kwd>tetrafluoroethane</kwd><kwd>phantom</kwd></kwd-group></article-meta></front><back><ref-list><ref id="ref1"><mixed-citation publication-type="other" xml:lang="ru">Пат. 2611905 C2 РФ, МПК G09B 23/28.
