На предоперационном этапе обследованы 18 пациентов, 11 больных с диагнозом «глиобластома» (ГБ) и 7 - с диагнозом «анапластическая астроцитома» (АА), которым были выполнены МРТ и ПЭТ-КТ с 11С-метионином и 18F-фтордезоксиглюкозой (ФДГ). Проводился сравнительный анализ показателей стандартизованного уровня накопления (SUV) РФП в опухоли и интактной ткани головного мозга, а также оценка индекса накопления (ИН) РФП, который был представлен отношением среднего уровня метаболизма РФП в участке максимальной активности опухоли к фоновому накоплению РФП в неизмененной ткани головного мозга. Группа АА статистически значимо отличалась от ГБ как по ИН 11С-метионина (1,62 ± 0,71 против 3,97 ± 1,04 соответственно; p &lt; 0,001), так и по ИН 18F-ФДГ (0,64 ± 0,11 у АА против 1,25 ± 0,66 у ГБ; p = 0,02). Уровни накопления 11С-метионина и 18F-ФДГ в неизмененной ткани головного мозга коррелировали между собой со значением R = 0,61. Зоны наиболее высокого включения различных РФП в строме новообразования в отдельных случаях не совпадали. Данная работа показала, что накопление 11C-метионина и 18F-ФДГ в глиальных опухолях головного мозга существенно отличается в зависимости от степени злокачественности, что позволило дифференцировать АА от ГБ, однако для улучшения практической значимости исследования необходимо отдельно изучить группу анапластических олигодендроглиом (Grade III), схожих по своим метаболическим характеристикам с ГБ.</p></abstract><trans-abstract xml:lang="en"><p>Purpose of the study is investigation of the possibilities of Positron Emission Tomography - Computed Tomography (PET-CT) with different radiopharmaceuticals in non-invasive differential diagnosis of primary high grade gliomas. 18 patients, 11 with glioblastoma (GB) and 7 with anaplastic astrocytoma (AA), were examined before surgery with magnetic resonance imaging (MRI) and PET-CT with 11С-methionine (MET) and 18F-fluorodeoxyglucose (FDG). The analysis was carried out according to the standardized uptake value (SUV) in the tumor and healthy brain tissue, and tumor to normal (T/N) ratio. AA and GB groups are significantly different in T/N ratio for 11C-MET (1,62 ± 0,71 in AA versus 3,97 ±1,04 in GB, p &lt; 0,001), and for 18F-FDG (0,64 ± 0,11 in AA versus 1,25 ± 0,66 in GB, p = 0,02). Levels of accumulation of 11C-MET and 18F-FDG in intact brain tissue correlate with each other (value of R2 = 0,61). The areas of high accumulation of two radiopharmaceuticals in the tumor stroma do not coincide. Our study demonstrated that the accumulation of 18F-FDG and 11C-methionine in HGG significantly depends on tumor grade. To improve practical value of this study patients with anaplastic oligodendrogliomas (Gr III), which are metabolically similar to GB, must be added to the comparison group.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>позитронно-эмиссионная томография</kwd><kwd>злокачественные глиомы головного мозга</kwd><kwd>дифференциальная диагностика злокачественных глиом</kwd><kwd>анапластическая астроцитома</kwd><kwd>глиобластома</kwd></kwd-group><kwd-group xml:lang="en"><kwd>11С-метионин</kwd><kwd>18F-ФДГ</kwd><kwd>11C-methionine</kwd><kwd>18F-fluorodeoxyglucose</kwd><kwd>Positron Emission Tomography</kwd><kwd>High Grade Gliomas</kwd><kwd>Anaplastic Astrocytoma</kwd><kwd>Glioblastoma</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">Золотова С.
