To compare the diagnostic performance of digital breast tomosynthesis (DBT) and digital mammography (DM) for breast cancers. Materials and Methods . The study included fifty-seven patients with histologically verified breast cancer. Given the subjective evaluation of the benefits of technology for tomosynthesis imaging of pathological signs characteristic of breast cancer (tumour, focal asymmetry, restructuring or microcalcifications). The data obtained on the base of DM and additional DBT information were assessed according to BI-RADS scale (force BI-RADS). The interdependence between the categories according to BI-RADS scale and the nature of the radiological manifestations of breast cancer was determined using Chi-square (c                  2) test. Results . A total of 59 breast cancers were reviewed, including 17 (28.8%) mass lesions, 12 (20.3%) focal asymmetry/density, 6 (10.2%) restructuring, 23 (39.0%) calcifications, and 1 (1.7%) intracystic tumor. Mammography with DBT was more informative to visualize 58.8% of the lesions, 83,3% of focal asymmetry, 94.4% of violations architectonics and only 11.6% of the signs of microcalcifications. When making conclusion on BI-RADS scale, in 84.4% of cases category of findings was increased from 0 (when performing DM) to 4 or 5 (when performing DBT). Category opinions 4A on the scale of BI-RADS in the implementation of DM in 27.3% of cases was increased after evaluation of the images of the DBT, a symptom of malignancy in this category were mainly detected microcalcifications. Significant interdependence ( p &lt; 0,001) between BI-RADS category and pathological radiographic signs was noted. Conclusion . DBT allows to obtain more accurate visual information about mass formation, focal asymmetry, violation of the architectonics and improves the diagnostic efficacy of mammography.</abstract><trans-abstract xml:lang="ru">Сравнение диагностической эффективности цифрового томосинтеза (DBT) и цифровой маммографии (DM) при непальпируемом раке молочной железы. Материалы и методы. В исследование было включено пятьдесят семь пациенток с гистологически подтвержденным раком молочной железы. Дана субъективная оценка преимуществам технологии томосинтеза для визуализации патологических признаков, характерных для рака молочной железы (объемное образование, очаговая асимметрия, перестройка структуры или микрокальцинаты). Данные, полученные при выполнении только DM и с учетом дополнительной информации, полученной при выполнении DBT, оценены по шкале BI-RADS (force BI-RADS). Взаимозависимость категории по шкале BI-RADS и характером рентгенологических проявлений рака молочной железы определялась с помощью теста хи-квадрат (c                  2). Результат. Всего было рассмотрено 59 случаев рака молочной железы, из них 17 (28,8%) - объемные образования, 12 (20,3%) - очаговая асимметрия/плотность, 6 (10,2%) - нарушения архитектоники, 23 (39,0%) - микрокальцинаты и 1 (1,7%) - внутрикистные образования. Маммография с DBT оказалась более информативной для визуализации 58,8% объемных образований, 83,3% очаговой асимметрии, 94,4% нарушений архитектоники и только в 11,6% признаков микрокальцификации. При вынесении заключений по шкале BI-RADS в 84,4% случаев категория заключений была повышена от 0 (при выполнении цифровой маммографии) до 4 или 5 (при выполнении цифрового томосинтеза). Категория заключений 4А по шкале BI-RADS при выполнении цифровой маммографии в 27,3% случаев была повышена после оценки изображений цифрового томосинтеза, признаком злокачественности этой категории были, в основном, микрокальцинаты. Отмечалась значимая величина критерия взаимозависимости P (&lt; 0,001) категории BI-RADS и патологических рентгенологических признаков. Заключение. Технология цифрового томосинтеза дает возможность получить более точную визуальную информацию об объемном образовании, очаговой асимметрии, нарушении архитектоники и повышает диагностическую эффективность маммографии.</trans-abstract><kwd-group xml:lang="en"><kwd>gynecology</kwd><kwd>radiation dose</kwd><kwd>impalpable masses</kwd><kwd>image interpretation</kwd><kwd>radiation exposure</kwd><kwd>mammography</kwd><kwd>breast X-ray</kwd><kwd>a series of images</kwd><kwd>comparative analysis</kwd><kwd>superposition of tissue structures</kwd><kwd>microcalcifications</kwd><kwd>tomosynthesis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гинекология</kwd><kwd>дозовая нагрузка</kwd><kwd>непальпируемые образования</kwd><kwd>интерпретация изображения</kwd><kwd>лучевая нагрузка</kwd><kwd>маммография</kwd><kwd>молочная железа</kwd><kwd>рентгеновский аппарат</kwd><kwd>серия снимков</kwd><kwd>сравнительный анализ</kwd><kwd>суперпозиция тканевых структур</kwd><kwd>микрокальцинаты</kwd><kwd>томосинтез</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Mettlin C.
