Двумерная эластография сдвиговой волной осуществлялась на аппарате Aixplorer (SuperSonic Imagine, Франция) широкополосным линейным датчиком с диапазоном частот от 4,0 до 15,0 МГц. Значения модуля Юнга измерялись в области микролитов и неизмененной паренхимы. Сравнения проводились с контрольной группой пациентов. Размеры микролитов колеблются от 0,7 до 2,9 мм (n = 60). При эластографии сдвиговой волной в рекомендованном диапазоне значений модуля Юнга (50 кПа) отмечается однородное окрашивание внутри цветового окна, невзирая на наличие неоднородности ткани яичка в серошкальном режиме. Определяются достоверные различия значений модуля Юнга (Emean и Emax), измеренных в области микролитов и неизмененной паренхимы. При сравнении с контрольной группой достоверные различия определяются только для участков с микролитами, тогда как значения модуля Юнга неизмененной паренхимы (вне микролитов) достоверно от группы контроля не отличаются. Размеры микролитов не коррелируют со значениями эластографических параметров. При оценке жесткости паренхимы яичек в случаях микролитиаза измерения желательно проводить в свободных от гиперэхогенных структур участках, при наличии множественных гиперэхогенных структур необходимо иметь в виду факт их влияния на количественные значения параметров жесткости.</p></abstract><trans-abstract xml:lang="en"><p>Testes parenchyma stiffness assessment was performed in patients with limited (less than five microliths) and classic microlithiasis (with five or more microliths on any single view). The study was performed on Aixplorer scanner (SuperSonic Imagine, France) with wideband linear probe (4-15 MHz). Young’s modulus values were assessed with microliths in the ROI and in normal parenchyma. Comparison with the control group was done. Microliths size varied from 0.7 to 2.9 mm (n = 60). Despite of the testis heterogeneity on gray scale ultrasound homogenous staining in the color window was seen during the shear wave elastography with the recommended range of the Young’s modulus (50 kPa). There were significant differences between the Young’s modulus values (Emean and Emax) assessed in microliths area and normal parenchyma. Comparison with the control group showed significant differences for microliths area only. There was not any significant difference of Young’s modulus within the normal parenchyma comparing to the control group. Size of microliths did not correlate with elastography parameters. It is recommended to assess stiffness of testes parenchyma avoiding hyperechoic areas. Multiple hyperechoic structures can affect on quantitative stiffness characteristics.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мультипараметрическая ультразвуковая диагностика</kwd><kwd>ультразвуковая эластография</kwd><kwd>эластография сдвиговой волной</kwd><kwd>жесткость</kwd><kwd>модуль Юнга</kwd><kwd>скорость сдвиговой волны</kwd><kwd>микролитиаз яичек</kwd><kwd>multiparametric ultrasound</kwd><kwd>ultrasound elastography</kwd><kwd>shear wave elastography</kwd><kwd>stiffness</kwd><kwd>Young’s modulus</kwd><kwd>shear wave velocity</kwd><kwd>testicular microlithiasis</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">Richenberg J., Belfield J., Ramchandani P. et al.
