Новообразования печени выявляются у довольно значительного и постепенно возрастающего количества больных. Ультразвуковое исследование (УЗИ) является методом выбора в диагностике новообразований печени. Ограничения традиционных методов УЗИ хорошо известны. Мультипараметрическое ультразвуковое исследование включает все доступные технологии, комплексное применение которых может значительно повысить диагностические возможности метода.</p></sec><sec><title>Цель</title><p>Цель. Оценка возможностей мультипараметрического УЗИ в дифференциальной диагностике новообразований печени.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Проведен ретроспективный анализ результатов обследования 172 пациентов с морфологически верифицированными новообразованиями печени. Комплекс диагностических методов включал проведение мультипараметрического УЗИ.</p></sec><sec><title>Результаты</title><p>Результаты. Традиционные методы УЗИ в дифференциальной диагностике новообразований печени обладают достаточно низкой специфичностью: признак «четкость контура» был характерен для гемангиом, гепатоцеллюлярных аденом (ГЦА), метастазов и зафиксирован в 82, 100, 96% случаев соответственно; при всех нозологических формах отмечен признак «неоднородная эхоструктура»; группы гепатоцеллюлярных карцином (ГЦК), метастазов в печени (МТС) и гепатоцеллюлярных аденом характеризовались очагами различных видов эхогенности. Специфические симптомы отмечены в группах пациентов с МТС (32%) и фокальной нодулярной гиперплазией (ФНГ) (96%). Внутриопухолевый кровоток зафиксирован в 34 (19,7%) случаях. Изучение спектральных характеристик было возможно только у 11 (6,4%) пациентов. При использовании контрастно-усиленного УЗИ статистически значимые различия параметров «начало контрастирования в очаге» выявлены между группами «ФНГ &amp; гемангиома» (р &lt; 0,000046), «ФНГ &amp; ГЦА» (р &lt; 0,006293), «MТС &amp; ФНГ» (р &lt; 0,028125), «ФНГ &amp; ГЦК» (р &lt; 0,024933), «время максимального накопления ультразвукового контрастного препарата в очаге» – «ФНГ &amp; гемангиома» (р &lt; 0,012590), «ФНГ &amp; ГЦК» (р &lt; 0,007983), «МТС &amp; ГЦК» (р &lt; 0,000243). Статистически значимые различия по времени вымывания ультразвукового контрастного препарата получены в группах «МТС &amp; ГЦК» и «МТС &amp; ГЦА».</p></sec><sec><title>Выводы</title><p>Выводы. Традиционные методы УЗИ должны использоваться в качестве базового скрининга, динамического наблюдения и навигации при биопсии новообразований. Контрастно-усиленное УЗИ в рамках мультипараметрического УЗИ расширяет возможности метода, позволяя проводить дифференциальную диагностику новообразований печени.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Liver lesions are increasingly found in a huge number of patients. Ultrasound (US) is the method of choice in liver lesion characterization. The limitations of traditional US techniques are well known. Multiparametric ultrasound (MPUS) includes multiple facets of the US examination, and their combination can significantly improve the diagnostic capabilities of the method.</p></sec><sec><title>Objective</title><p>Objective. To evaluate the capabilities of MPUS in the differential diagnosis of liver tumors.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. A retrospective analysis included 172 patients with morphologically confirmed liver tumors. All patients underwent an MPUS examination.</p></sec><sec><title>Results</title><p>Results. Traditional US techniques have a rather low specificity in the differential diagnosis of liver neoplasms: the sign of “contour clarity” was typical for hemangiomas, hepatocellular adenomas (HCA), liver metastases and was recorded in 82, 100, 96% cases, respectively; heterogeneous echostructure was noted in all nosological entities, groups of hepatocellular carcinomas (HCC), liver metastases and HCA were characterized by foci of various types of echogenicity. Specific symptoms were discovered in patients with liver metastases (32%) and focal nodular hyperplasia (FNH) (96%). Intratumoral blood flow was recorded in 34 (19.7%) cases. The study of spectral characteristics was possible only in 11 (6.4%) patients. Statistically significant differences in contrast-enhanced US parameters “contrasting onset in focus” were found between the groups “FNH &amp; hemangioma” (р &lt; 0.000046), “FNH &amp; HCA” (р &lt; 0.006293), “MTS &amp; FNH” (р &lt; 0.028125), “FNH &amp; HCC” (р &lt; 0.024933), “maximum fill-in time” – “FNH &amp; hemangioma” (р &lt; 0.012590), “FNH &amp; HCC” (р &lt; 0.007983), “MTS &amp; HCC” (р &lt; 0.000243). Statistically significant differences in the wash-out time were obtained in “MTS &amp; HCC” and “MTS &amp; HCA” groups.</p></sec><sec><title>Conclusion</title><p>Conclusion. Conventional US should be used as basic screening, follow-up and navigation in the neoplastic biopsy. Contrast-enhanced US within MPUS is currently a well-established technique which allows a more precise and confident diagnosis of liver tumors.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>контрастно-усиленное ультразвуковое исследование</kwd><kwd>мультипараметрическое ультразвуковое исследование</kwd><kwd>новообразования печени</kwd></kwd-group><kwd-group xml:lang="en"><kwd>contrast-enhanced ultrasound</kwd><kwd>multiparametric ultrasound</kwd><kwd>liver lesions</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">Практическое руководство по ультразвуковой диагностике.
