Assessment of the stages of liver fibrosis and steatosis is prognostically significant in diagnosis of NAFLD. Routine diagnostic methods are either not able to accurately assess the severity of fibrosis and steatosis (ultrasound, laboratory tests), or cannot be used as a simple screening tool (liver biopsy) due to such limitations as invasiveness, dependence on pathologist qualification, high cost, and limited region of interest. Over the last two decades, the great progress has been made in non-invasive visualization of pathological changes in liver diseases. In this review, we examined the diagnostic characteristics of the most widely used non-invasive imaging methods in clinical practice, available for quantitative determination of fat and fibrosis in the liver: transient elastography with controlled attenuation parameter (CAP), acoustic radiation force impulse (ARFI) and shear wave elastography (SWE). Comparing these methods and their limitations, we came to conclusion, that elastographic methods (slightly more ARFI and SWE) are able to verify the F3, F4 stages of fibrosis in NAFLD with high sensitivity and specificity (&gt;90%); however, they are less accurate for early stages. Elastographic techniques have moderate accuracy in identifying the degree of steatosis due to the lack of uniform standardized cut-off values of CAP.</title></abstract><trans-abstract xml:lang="ru"><p>В настоящее время наблюдается рост распространенности одного из самых часто встречающихся диффузных хронических заболеваний печени ― неалкогольной жировой болезни печени. Прогностически значимой в диагностике данного заболевания считается оценка стадий фиброза и стеатоза печени. Обычные методы диагностики либо не способны с высокой точностью оценить выраженность фиброза и стеатоза (ультразвуковое исследование, лабораторные тесты), либо не могут быть использованы в качестве простого скрининга (биопсия печени) вследствие своих ограничений (инвазивность, зависимость от квалификации морфолога, высокая стоимость, ограниченный участок исследования). За последние два десятилетия огромные успехи были достигнуты в неинвазивной визуализации патоморфологических изменений при болезнях печени. В этом обзоре мы изучили диагностические характеристики наиболее широко применяющихся в клинической практике неинвазивных методов визуализации, доступных для количественного определения жира и фиброза в печени: транзиентную эластографию с контролируемым параметром затухания (CAP), акустическое радиационное давление, эластографию сдвиговых волн. Сравнивая вышеперечисленные методы и их ограничения, мы пришли к выводу, что на сегодняшний день эластографические методы (немного в большей степени акустическое радиационное давление и эластография сдвиговых волн) способны с высокой чувствительностью и специфичностью (&gt;90%) верифицировать F3-, F4-стадии фиброза при неалкогольной жировой болезни печени, но менее достоверны в отношении ранних стадий. Степени стеатоза распознаются с умеренной точностью, что связано с отсутствием единых стандартизированных пороговых значений CAP.</p></trans-abstract><kwd-group xml:lang="en"><kwd>nonalcoholic fatty liver disease</kwd><kwd>liver fibrosis</kwd><kwd>elastography</kwd><kwd>acoustic radiation force impulse</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>неалкогольная жировая болезнь печени</kwd><kwd>фиброз печени</kwd><kwd>транзиентная эластография</kwd><kwd>акустическое радиационное давление</kwd><kwd>сдвиговая волна</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Проект повышения конкурентоспособности ведущих российских университетов среди ведущих мировых научно-образовательных центров</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
