One hundred and two patients with glial brain tumors were included in the study. Depending on the degree of malignancy patients were divided into 2 groups: group 1–38 (37.26 %) patients with grade I–II tumors; group 2–64 (62.74 %) patients with grade III–IV tumors. Perfusion CT was performed in 20 (52.6 %) patients from the group with grade I–II tumors and 37 (57.8 %) patients from the group with grade III–IV gliomas. The sensitivity and specificity of such indicators as the maximum standardized uptake value (maxSUV) and the tumor to brain ratio (TBR), in combination with CT perfusion indicators (cerebral blood flow (CBF), cerebral blood volume (CBV), vascular permeability (FED) were studied.</p><p><bold>Results</bold>. The highest diagnostic accuracy was demonstrated by the following parameters: maxSUV 1 (sensitivity and specificity 81 and 82 %, threshold value 2.51, AUC 0.87); TBR <sub>1</sub> (sensitivity and specificity 90.6 and 81.6 %, threshold value 2.07, AUC 0.89). The comprehensive evaluation of CT perfusion and <sup>18</sup> F-fluoroethyltyrozine PET / CT parameters: sensitivity and specificity of TBR <sub>1</sub> + CBF – 97.1 and 94.4 %, respectively; TBR <sub>1</sub> + CBV – 96.6 and 94.4 %, respectively; TBR <sub>1</sub> + FED – 94.6 and 92.3 %, respectively.</p><p><bold>Conclusion</bold>. According to results of obtained analysis, an increase in diagnostic accuracy was revealed for all studied parameters with complex use of two methods – <sup>18</sup> F-fluoroethyltyrozine PET / CT and CT perfusion, in differential diagnosis of glial brain tumors.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования</bold> – оценка возможностей комплекса методов визуализации (позитронной эмиссионной томографии (ПЭТ) с <sup>18</sup> F-фторэтилтирозином, совмещенной с компьютерной томографией (КТ), и перфузионной КТ) в дифференциальной диагностике глиальных опухолей головного мозга разной степени злокачественности.</p><p><bold>Материалы и методы</bold>. В исследование включены 102 пациента с глиальными опухолями головного мозга. В 1-ю группу вошли 38 (37,26 %) пациентов с глиальными образованиями I–II степени злокачественности; во 2-ю группу – 64 (62,74 %) пациента с глиомами III–IV степени. Перфузионная КТ выполнена у 20 (52,6 %) пациентов 1-й группы и 37 (57,8 %) пациентов 2-й группы. Исследованы чувствительность и специфичность таких показателей, как максимальный уровень накопления радиофармпрепарата (maxSUV) и отношение maxSUV в патологическом очаге к уровню накопления в неизмененном веществе головного мозга (TBR), в сочетании с показателями перфузионной КТ (скорость мозгового кровотока CBF, объем мозгового кровотока CBV, сосудистая проницаемость FED).</p><p><bold>Результаты</bold>. Наибольшую диагностическую точность имели показатели maxSUV (чувствительность и специфичность соответственно 81 и 82 %, пороговое значение 2,51, AUC 0,87), TBR (чувствительность и специфичность 90,6 и 81,6 %, пороговое значение 2,07, AUC 0,89) на 1-м этапе сканирования. При комплексной оценке данных перфузионной КТ и ПЭТ/КТ с <sup>18</sup> F-фторэтилтирозином установлено, что чувствительность и специфичность сочетания TBR и CBF составляют соответственно 97,1 и 94,4 %, сочетания TBR и CBV – 96,6 и 94,4 %, сочетания TBR и FED – 94,6 и 92,3 %.</p><p><bold>Заключение</bold>. Выявлено увеличение чувствительности и специфичности диагностики глиальных опухолей в части оценки степени их анаплазии при комплексном использовании ПЭТ/КТ с <sup>18</sup> F-фторэтилтирозином и перфузионной КТ.</p></trans-abstract><kwd-group xml:lang="en"><kwd><sup>18</sup> F-fluoroethyltyrozine positron emission tomography</kwd><kwd><sup>18</sup> F-fluoroethyltyrozine</kwd><kwd>computed tomography</kwd><kwd>glioma</kwd><kwd>computed tomography perfusion</kwd><kwd>brain</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>позитронная эмиссионная томография</kwd><kwd><sup>18</sup> F-фторэтилтирозин</kwd><kwd>компьютерная томография</kwd><kwd>глиома</kwd><kwd>перфузия</kwd><kwd>головной мозг</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Bondy M.L., Scheurer M.E., Malmer B. et al.
