Проведен статистический анализ полученных данных.</p></sec><sec><title>Результаты</title><p>Результаты: Разработанный нами комплекс семиотических МРТ-признаков, включающий умеренную гиперинтенсивность новообразования в нативную и последующие фазы внутривенного контрастирования (в т.ч. ГБФ), умеренную гиперинтенсивность на ДВ-МРТ при b-факторе 800 и 400 c/мм2, а также наличие капсулы, позволяет дифференцировать ГЦК с редко встречающимся и нетипичным характером контрастирования у пациентов с циррозом печени от ФНГ.</p></sec><sec><title>Выводы</title><p>Выводы: МРТ с использованием гадоксетовой кислотой в сочетании с ДВ-МРТ играет важную роль в диагностике новообразований печени и позволяет дифференцировать редко встречающиеся формы ГЦК с нетипичным характером контрастирования без морфологической верификации.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose</title><p>Purpose: The article describes a variety of liver lesions, hyperintensity in the hepatobiliary phase of gadoxetic acid-enhanced MRI and the added value of gadoxetic acid in their differential diagnosis with consideration of its pharmacokinetics.</p></sec><sec><title>Material and methods</title><p>Material and methods: Gadoxetic acid-enhanced MRI scans of 19 patients with slight hyperintensity lesions in the hepatobiliary phase, were retrospectively assessed, the role of DWI in differential diagnosis of rare types of hepatocellular carcinoma (HCC) and focal nodular hyperplasia (FNH) was evaluated and the statistical analysis was performed.</p></sec><sec><title>Results</title><p>Results: The combination of evaluated MRI semiotics features — hyperintensity in native, arterial, portal venous and hepatobiliary phases, slight hyperintensity on DWI (b-value 800 and b-value 400 s/mm2), rim enhancement (“capsule”) — enables differentiation of rare types of HCC and HCC with atypical enhancement in patients with FNH.</p></sec><sec><title>Conclusion</title><p>Conclusion: MRI with hepatobiliary contrast agents in junction with DWI increases the accuracy of identification of liver lesions and allows differentiation of rare types of HCC with atypical enhancement in patients with FNH without morphological verification.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>диффузионно-взвешенная МРТ</kwd><kwd>гадоксетовая кислота</kwd><kwd>гепатоцеллюлярный рак</kwd><kwd>фокальная нодулярная гиперплазия</kwd><kwd>дифференциальная диагностика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>MRI</kwd><kwd>gadoxetic acid</kwd><kwd>DWI-MRI</kwd><kwd>HCC</kwd><kwd>FNH</kwd><kwd>differential diagnosis</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">Siegel RL, Miller KD, Fuchs HE, et al.
