Исследованы диффузионно-взвешенные изображения 39 пациентов с глиомами головного мозга. Для каждой опухоли рассчитаны ИКД, клеточная плотность и индекс пролиферативной активности Ki-67, выполнен корреляционный анализ между ними.</p></sec><sec><title>Результаты</title><p>Результаты. При сравнении средних значений ИКД получено достоверное различие между опухолями G=I–II и G=III–IV. Сравнение средних значений индекса Ki-67 между глиомами различной степени злокачественности показало наличие статистически значимых различий. При оценке корреляции между ИКД и значениями индекса пролиферативной активности Ki-67 отмечена умеренная и выраженная обратная корреляционная зависимость соответственно для глиальных опухолей низкой и высокой степени злокачественности.</p></sec><sec><title>Заключение</title><p>Заключение. Методика ДВ МРТ с подсчетом ИКД может быть использована в качестве дополнительного неинвазивного метода предоперационной оценки степени злокачественности и пролиферативного потенциала глиом головного мозга.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective.

Diffusion-weighted images of 39 patients with brain gliomas were studied. MDC, cell density, and Ki-67 proliferative activity index were calculated for each tumor.

Comparison of the mean values for MDC revealed a significant difference between grades I–II and III–IV tumors. There were statistically significant differences in the mean Ki-67 index between different grades of gliomas. Evaluation of the correlation between MCD and Ki-67 proliferative activity index demonstrated moderate and strong inverse correlations for low- and high-grade tumors, respectively.</p></sec><sec><title>Conclusion</title><p>Conclusion.
