В качестве основы использовали расширенный набор компьютерных томограмм головного мозга с наличием и отсутствием признаков внутричерепного кровоизлияния, дополненный клиническими и техническими параметрами. Из набора выбрали 176 исследований (106 ‒ для обучения, 70 – для тестирования), которые специальным образом подготовили для подачи в нейронную сеть: сегментировали с выделением области интереса (головной мозг), нормализовали, удалили фон. В качестве базовой нейронной сети использовали нейросетевую архитектуру ResNet10, способную анализировать трехмерные медицинские изображения. Она была объединена с другой нейронной сетью для формирования архитектуры ResNet10_Meta, которая с помощью подхода One-Hot-Enconding (OHE) подключает к анализу непосредственно изображений другие метаданные. В качестве метаданных выбрали четыре параметра: Manufacturer, SliceThickness, PatientAge, XrayTubeCurrent. Результаты. Проведено 12 экспериментов по обучению нейронной сети с поочередным присоединением одного, двух или всех дополнительных параметров. Модель с добавлением параметра XTube продемонстрировала наиболее высокую специфичность (82,3 %, 95%-й доверительный интервал (95 % ДИ) [69,6–94,9]), превосходя базовую модель Baseline без подключения дополнительных метаданных (специфичность 79,4 %, 95 % ДИ [66,0–92,8]). Чувствительность модели c добавлением нескольких метаданных (XTube + SliceT) была сравнительно больше (69,7 %, 95 % ДИ [54,5–84,9]), чем модели Baseline. Модель с добавлением всех метаданных «All params» существенных улучшений не продемонстрировала. Однако все найденные различия оказались статистически незначимыми (p &gt; 0,05).Заключение. Наши данные продемонстрировали отсутствие статистически значимых различий в производительности нейронной сети, анализирующей диагностические изображения без учета или с учетом метаданных, добавляемых к обучающему набору данных. Тем не менее данное исследование пилотное и проведено на ограниченной выборке, поэтому еще предстоит выяснить, могут ли коммерчески доступные инструменты искусственного интеллекта быть абсолютно нечувствительными к техническим характеристикам изображений.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the study is to evaluate the impact of metadata added to the training dataset on the performance of an artificial intelligence system aimed at working with diagnostic brain images. Material and Methods. An expanded set of computed tomography scans of the brain with and without signs of intracranial haemorrhage, supplemented with clinical and technical parameters, was used as a basis. From the dataset, 176 studies were selected (106 for training, 70 for testing), which were specially prepared for input into the neural network: they were segmented with the region of interest (the brain) highlighted, normalized, and the background was removed. The ResNet10 neural network architecture, which is capable of analyzing 3D medical images, was used as the underlying neural network. It was combined with another neural network to form the ResNet10_Meta architecture, which, using a One-HotEnconding (OHE) approach, connects other metadata to analyze images directly. Four parameters were selected as metadata: ‘Manufacturer’, ‘SliceThickness’, ‘PatientAge’, and ‘XrayTubeCurrent’. Results. Twelve experiments were conducted to train the neural network with one, two, or all of the additional parameters added alternately. The model with the addition of the ‘XTube’ parameter showed the highest specificity (82.3 %, 95 % confidence interval (95 % CI) [69.6–94.9]), outperforming the Baseline model without additional metadata (specificity 79.4 %, 95 % CI [66.0–92.8]). The ‘XTube + SliceT’ model with the addition of multiple metadata showed comparatively higher sensitivity (69.7 %, 95 % CI [54.5–84.9]) relative to Baseline model. The model with the addition of all metadata ‘All params’ did not show significant improvements. However, all differences found were statistically insignificant (p &gt; 0.05). Conclusions. Our data demonstrated that there were no statistically significant differences in the performance of a neural network analyzing diagnostic images without or with metadata added to the training dataset. However, this study is pilot and was conducted on a limited sample, so it remains to be seen whether commercially available artificial intelligence tools can be completely insensitive to image specifications.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>компьютерная томография</kwd><kwd>искусственный интеллект</kwd><kwd>внутричерепные кровоизлияния</kwd><kwd>головной мозг</kwd><kwd>наборы данных</kwd></kwd-group><kwd-group xml:lang="en"><kwd>computed tomography</kwd><kwd>intracranial hemorrhage</kwd><kwd>artificial intelligence</kwd><kwd>brain</kwd><kwd>training dataset</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках НИОКР «Разработка платформы подготовки наборов данных лучевых диагностических исследований» (№ ЕГИСУ: 123031500003-8) в соответствии с Приказом от 21.12.2022 № 1196 «Об утверждении государственных заданий, финансовое обеспечение которых осуществляется за счет средств бюджета города Москвы государственным бюджетным (автономным) учреждениям подведомственным Департаменту здравоохранения города Москвы, на 2023 год и плановый период 2024 и 2025 годов» Департамента здравоохранения города Москвы.</funding-statement><funding-statement xml:lang="en">This work was carried out as part of the research and development effort titled “Development of a platform to generate data sets containing diagnostic imaging studies” (USIS No.: 123031500003-8) in accordance with the Order No. 1196 dated December 21, 2022 “On approval of state assignments funded by means of allocations from the budget of the city of Moscow to the state budgetary (autonomous) institutions subordinate to the Moscow Health Care Department, for 2023 and the planned period of 2024 and 2025” issued by the Moscow Health Care Department.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Kwee T.C., Kwee R.M.
