To evaluate the diagnostic capabilities of combined positron emission tomography (PET) with accumulation of 18-fluorodeoxyglucose and computed tomography (CT) data, with additional 3D-visualization of CT DICOM files using the 3D Slicer software, in detecting tumor invasion of the paragastric tissue in locally advanced gastric cancer.Materials and methods. A prospective open-label study was conducted as part of the research project “SmartGastro”. Four women and four men aged 51 to 81 years with a histologically confirmed diagnosis of gastric cancer underwent combined PET/CT following the “Whole Body” protocol at 60–80 minutes after the administration of the radiopharmaceutical agent (RPA). The obtained results were analyzed through visual assessment of CT and PET images separately, as well as through fused scans, followed by 3D reconstruction based on CT DICOM data. All patients underwent surgery. The resected macroscopic specimen was stepwise excised along its perimeter, followed by a histological examination of the resection margins (paragastric fat tissue). In all cases, R0 resection was confirmed, indicating radical tumor removal. The initial delineation of tumor boundaries based on PET-CT and CT imaging was compared voxel-by-voxel with the secondary delineation performed through a visual assessment of the excised macroscopic specimen.Results. In 5 out of 8 cases, compromised peritumoral paracardial tissue detected on CT corresponded to regions of radiopharmaceutical agent uptake on PET. Areas demonstrating increased RPA accumulation in the peritumoral tissue, along with a corresponding rise in densitometric values on CT, were indicative of true invasion. This was confirmed by a histological examination of the resected specimen, in 6 out of 8 cases. The sensitivity of combined PET/CT, assessed on a voxel-by-voxel basis against postoperative pathological findings, was 0.88 (95% confidence interval (CI): 0.76–0.97), while specificity reached 0.91 (95% CI: 0.80–0.99). The discrepancy in tumor boundaries between these modalities, determined using the Hausdorff distance, was 5.2 mm, with a mean tumor size of 38×30×39 mm. Conclusion. Combined PET/CT enables the surgeon to identify precisely a compromised mesolayer adipose tissue.The construction of 3D-models of perigastric tissues affected by the tumor process, combined with the visualization of the gastric tumor and associated vasculature, facilitates comprehensive preoperative planning for oncological surgery.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Оценить диагностические возможности совмещенной позитронно-эмиссионной томографии (ПЭТ) с накоплением 18-фтордезоксиглюкозы и компьютерной томографии (КТ), дополненных 3D-визуализацией DICOM-файлов с помощью программы 3D Slicer, в выявлении опухолевой инвазии парагастральной клетчатки при местнораспространенном раке желудка.Материалы и методы. Проведено открытое проспективное исследование в рамках научно-исследовательского проекта «SmartGastro». В исследование включены 4 женщины и 4 мужчин в возрасте от 51 до 81 года с гистологически подтвержденным диагнозом «рак желудка». Всем пациентам выполняли совмещенную ПЭТ-КТ по протоколу «Whole body» на 60–80-й минуте после введения радиофармпрепарата (РФП). Обработка полученных результатов включала визуальный анализ КТ- и ПЭТ-изображений как по отдельности, так и совмещенных сканов, а также 3D-реконструкцию на основании денситометрического анализа DICOM-данных. Все пациенты были прооперированы. Удаленный макропрепарат поэтапно иссечен по периметру с последующим гистологическим исследованием краев резекции (парагастральной клетчатки). Во всех случаях подтверждена радикальность вмешательства R0. Первичную разметку границ опухоли по ПЭТ-КТ и КТ сравнивали по вокселям со вторичной разметкой, выполненной на основании визуального анализа удаленного макропрепарата.Результаты. Компрометированная периопухолевая паракардиальная клетчатка по КТ в 5 из 8 наблюдений соответствовала зонам накопления РФП по ПЭТ. Участки повышенного накопления РФП в периопухолевой клетчатке и повышение денситометрической плотности этих же участков по данным КТ соответствовали истинной инвазии, подтвержденной при вторичной разметке, в 6 из 8 случаев. Чувствительность первичной разметки по совмещенной ПЭТ-КТ в сравнении по вокселям со вторичной разметкой составила 0,88 (95% доверительный интервал (ДИ) 0,76–0,97), специфичность – 0,91 (95% ДИ 0,80–0,99), расхождение границ опухоли, рассчитанное по расстоянию Хаусдорфа, составило 5,2 мм при средних размерах опухоли 38×30×39 мм.Заключение. Совмещенная ПЭТ-КТ позволяет точно определить области компрометированного мезослоя жировой клетчатки. Создание 3D-моделей компрометированных опухолевым процессом парагастральных тканей в сочетании с визуализацией опухоли желудка и сосудов способствует комплексному предоперационному планированию онкологических операций.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>опухоль желудка</kwd><kwd>мезогастральная клетчатка</kwd><kwd>ПЭТ-КТ</kwd><kwd>18-фтордезоксиглюкоза</kwd><kwd>медицинская визуализация</kwd><kwd>3D-реконструкция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gastric tumor</kwd><kwd>mesogastric tissue</kwd><kwd>PET/CT</kwd><kwd>18-fluorodeoxyglucose</kwd><kwd>medical imaging</kwd><kwd>3D-reconstruction</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">Yang W.J., Zhao H.P., Yu Y., et al.
