Также диффузионно-взвешенные изображения (ДВИ), получаемые с помощью ДВ МРТ, применяются с целью дифференциальной диагностики доброкачественных и злокачественных опухолей. Цель исследования – сопоставить полученные значения ИКД менингиом с клеточной плотностью и индексом пролиферативной активности опухоли Ki67. Материал и методы. В исследование включены магнитнорезонансные томограммы с ДВИ, выполненные 37 пациентам по поводу менингиом головного мозга. Измеряемый коэффициент диффузии (ИКД) вычислялся на ДВИ с наибольшим диаметром менингиомы, в область интереса не были включены кистозные и некротические зоны опухоли. При морфологическом исследовании менингиом оценивалась степень злокачественности по классификации ВОЗ, значение индекса пролиферативной активности Ki67 и клеточная плотность в опухолевой ткани. Результаты. В большинстве случаев выявлялись типические (MI) и атипические (MII) менингиомы – у 37,8 и 56,7 % пациентов соответственно. Анапластические (MIII) менингиомы верифицированы у 5,5 % пациентов. Среднее значение ИКД для менингиом MI составило 1375,5 ± 197,5 мм2 /сек. ИКД для менингиом MII и MIII cоставили 1113,1 ± 180 мм2 /сек и 689 ± 31,1 мм2 /сек соответственно. Значимые различия между средними значениями ИКД получены при сравнении менингиом МI и MIII (р=0,008) и менингиом MII и MIII (р=0,012). Достоверных различий между клеточной плотностью менингиом выявлено не было (для MI/MII, MII/MIII и MI/MIII – p=0,834, p=0,684, p=0,766 соответственно). Значимые различия между значениями индекса Ki67 обнаружены при сравнении групп менингиом MI и MIII (р=0,002), а также MII и MIII (р=0,007). Между ИКД и значениями индекса пролиферативной активности Ki67 отмечена выраженная корреляционная зависимость (r = –0,699, p=0,001). Заключение. Методика ДВ МРТ с подсчетом ИКД может быть использована в качестве дополнительного неинвазивного метода дифференциальной диагностики степени злокачественности менингиом головного мозга. </p></abstract><trans-abstract xml:lang="en"><p>Methods of diffusion-weighted magnetic resonance imaging (DW MRI) provides information on the microstructural state of various tissues and organs. Also, a diffusion-weighted image (DWI) obtained using DW MRI applied to the differential diagnosis of benign and malignant tumors. Purpose – to compare the values obtained ADC meningiomas with cell density and proliferative activity index Ki67 tumor. Material and methods. The study included DW MRI program with 37 patients for brain meningiomas. ADC was calculated on DWI with a maximum diameter of meningioma, in the area of interest have not been included cystic and necrotic areas of the tumor. When meningiomas morphological study assessed the degree of malignancy according to WHO classification, the index of Ki67 proliferative activity and cell density in tumor tissue. Results. In most typical cases detected (MI) and atypical (MII) meningiomas – at 37.8 % and 56.7 % of patients, respectively. Anaplastic (MIII) meningioma verified in 5.5 % of patients. The average value for meningiomas ADC MI was 1375,5 ± 197,5 mm2 /s. ADC for meningiomas MII and MIII costavili 1113.1 ± 180 mm2 /sec and 689 ± 31.1 mm2 /s, respectively. Statistically significant differences between the mean values obtained by comparing ADC meningiomas MI and MIII (p=0.008) and meningiomas MII and MIII (p=0.012). No significant differences between the cell density was not detected meningiomas (p=0,834, p=0,684 p=0,766 respectively for the MI/MII, MII/MIII and MI/MIII). Statistically significant differences between the values of Ki67 index were found when comparing the groups meningiomas MI and MIII (p=0.002) and MII and MIII (p=0.007). ADC between index values and proliferative activity of Ki67, expressed marked correlation (r=-0,699, p=0,001). Conclusion. DW MRI and ADC maps can be used as an additional non-invasive method of differential diagnosis brain meningioma gradation. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>менингиомы</kwd><kwd>диффузионно-взвешенная МРТ</kwd><kwd>измеряемый коэффициент диффузии</kwd><kwd>диффузионно-взвешенное изображение</kwd><kwd>клеточная плотность</kwd><kwd>Ki67</kwd></kwd-group><kwd-group xml:lang="en"><kwd>meningioma</kwd><kwd>diffusion weighted MRI</kwd><kwd>apparent diffusion coefficient</kwd><kwd>diffusion weighted image</kwd><kwd>cell density</kwd><kwd>proliferative activity index Ki67</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">Byvaltsev V.A., Stepanov I.A., Kalinin A.A., Shashkov K.V.
