Проведен ретроспективный анализ результатов обследования 165 пациентов с новообразованиями печени (177 узлов). Всем пациентам выполнялось контраст-усиленное ультразвуковое исследование (КУУЗИ) с присвоением категорий по критериям CEUS LI RADS v2017®. Разделение на группы проводилось на основании клинико-морфологических данных: 1 -я группа – 62 пациента с циррозом печени и/или хроническим вирусным гепатитом; 2- я группа – 110 пациентов без факторов риска развития гепатоцеллюлярной карциномы (ГЦК).</p></sec><sec><title>Результаты</title><p>Результаты. Диагностическая эффективность критериев CEUSLIRADSv2017® для верификации ГЦК составила: в 1- й группе Se – 100%, Sp – 88%, Ac – 95,5%; во 2 й группе Se – 100%, Sp – 68,8%, Ac – 72,7%; в общей группе Se – 100%, Sp – 72,2%, Ac – 81,4%. При этом во 2-й группе 21 из 22 новообразований, морфологически верифицированных как фокальная нодулярная гиперплазия (ФНГ), согласно критериям, были отнесены в категорию LR 4. Учитывая доброкачественный характер ФНГ и характерные паттерны контрастирования, при повторном анализе они были перенесены из категории LR 4 в LR 3, что позволило повысить чувствительность и специфичность во 2 -й группе в среднем на 20% (Se – 100%, Sp – 90,6%, Ac – 91,8%); а также увеличить точность диагностики в общей группе пациентов (Se – 100%, Sp – 90,1%, Ac – 93,2%). Диагностическая эффективность критериев CEUS LI RADS v2017® для злокачественных новообразований не гепатоцеллюлярной природы (LR М) составила: в 1 й группе: Se – 77,8%, Sp – 100%, Ac – 97%; во 2 -й группе: Se – 90%, Sp – 96,7%, Ac – 93,6%; в общей группе: Se – 88,1%, Sp – 98,3%, Ac – 94,9%.</p></sec><sec><title>Выводы</title><p>Выводы. Исследование подтвердило высокую точность критериев CEUS LI RADS v2017® в дифференциальной диагностике новообразований печени. Модификация системы (в частности, перенос типичных форм ФНГ из категории LR 4) сделает возможным повышение точности диагностики на 20%. Это позволит применять систему LI RADS v2017® для описания КУУЗИ не только среди пациентов с циррозом печени, но и в группе без факторов риска ГЦР.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: efficacy evaluation of the CEUS LI RADS v2017® system for differential diagnosis of liver tumors in patients with and without cirrhosis.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Retrospective analysis of diagnostic results of the 165 patients with liver tumors (177 nodules) was done. All patients underwent CEUS with results interpretation in accordance to the CEUS LIRADSv2017 ® criteria. Patients were divided into 2 groups based on clinical and morphological data. Group 1 included 62 patients with cirrhosis and/or CVH. Group 2 included 110 patients without risk factors for HCC.</p></sec><sec><title>Results</title><p>Results. Diagnostic efficiency of CEUS LI RADS v2017® for HCC identification was: group 1 – Se – 100%, Sp – 88%, Ac – 95.5%; group 2 – Se – 100%, Sp – 68.8%, Ac – 72.7%; general group Se – 100%, Sp – 72.2%, Ac – 81.4%. In the 2nd group, 21 out of 22 neoplasms, confirmed morphologically as FNH, we classified as LR 4. By applying benign character and specific contrasting patterns of FNG, they were transferred from LR 4 to LR 3. This allowed to increase sensitivity and specificity of differential diagnosis in group 2 (Se – 100%, Sp – 90.6%, Ac – 91.8%) and in general group (Se – 100%, Sp – 90.1%, Ac – 93.2%). Diagnostic efficiency of the criteria for non hepatocellular malignant neoplasms (LR M) was: group 1 – Se – 77.8%, Sp – 100%, Ac – 97%; group 2 – Se – 90%, Sp – 96.7%, Ac – 93.6%; general group- Se – 88.1%, Sp – 98.3%, Ac – 94.9%.</p></sec><sec><title>Conclusion</title><p>Conclusion. Our study confirmed high accuracy of the CEUS LI RADS v2017® system in the differential diagnosis of focal liver tumors. Modification of the system (in particular, transfer of typical FNG forms from the LR 4 category) will make it possible to increase the accuracy of diagnostics by 20%. It will allow to use the LI RADS v2017® system for interpretation CEUS not only among patients with liver cirrhosis, but also in a general group without risk factors of GCC.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>новообразования печени</kwd><kwd>КУУЗИ</kwd><kwd>CEUSLIRADS®</kwd></kwd-group><kwd-group xml:lang="en"><kwd>liver neoplasms</kwd><kwd>HCC</kwd><kwd>CEUS</kwd><kwd>CEUSLIRADS®</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">Бредер В.В., Косырев В.Ю., Ледин Е.В.
