Менингиомы – наиболее распространенные внемозговые интракраниальные объемные образования. Радикальность удаления менингиом во многом зависит от консистенции, размеров и близости расположения опухоли к важным анатомическим структурам. Предоперационное прогнозирование плотности менингиом имеет важное значение для выбора хирургического доступа и операционного оборудования, прогнозирования сложности операции, общей радикальности удаления опухоли и неврологического исхода после операции.</p><p>Цель исследования – выявление предикторов консистенции интракраниальных менингиом по данным магнитнорезонансной томографии с использованием методики Т1/Т2‑картирования.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование вошли 96 пациентов с первично выявленными менингиомами, прооперированные в ФГБУ «Федеральный центр нейрохирургии» (г. Новосибирск) в период с 2018 по 2021 г. Магнитнорезонансные изображения были проанализированы с использованием метода расчета отношения интенсивности сигнала на Т1‑взвешенных изображениях к сигналу на Т2‑взвешенных изображениях с последующим групповым и корреляционным статистическим анализом для сравнения результатов Т1/Т2‑картирования с клиническими, гистологическими и интраоперационными данными.</p></sec><sec><title>Результаты</title><p>Результаты. Выявлено статистически значимое повышение интенсивности сигнала и стандартного отклонения от средней интенсивности на Т1/Т2‑картах от псаммоматозных менингиом по сравнению со всеми остальными подтипами. Кроме того, выявлена положительная корреляция между значениями интенсивности сигнала от менингиом на Т1/Т2‑картах и интраоперационными данными о консистенции опухоли.</p></sec><sec><title>Заключение</title><p>Заключение. Изображения, полученные с помощью метода Т1/Т2‑картирования, не уступают классическим Т2‑взвешенным изображениям в оценке консистенции интракраниальных менингиом. Их преимуществом является возможность получения абсолютных значений интенсивности. Необходимы дальнейшие проспективные исследования для подтверждения полученных результатов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Meningiomas are the most common extracerebral intracranial neoplasms. Radicality of meningioma resection largely depends on its consistency, size, and closeness to important anatomical structures. Preoperative prognosis of meningioma density plays an important role in selection of surgical access and operative inventory, general radicality of tumor resection, and neurological outcome after surgery.</p></sec><sec><title>Aim</title><p>Aim. To determine predictors of intracranial meningioma consistency using magnetic resonance imaging and T1, T2‑mapping technique.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included 96 patients with primary meningiomas who underwent surgery at the Federal Neurosurgical Center (Novosibirsk) between 2018 and 2021. Magnetic resonance images were analyzed using calculation of the ratio between signal intensity on T1‑weighted and T2‑weighted images with subsequent group and correlation statistical analysis for comparison of T1, T2‑mapping results with clinical, histological and intraoperative data.</p></sec><sec><title>Results</title><p>Results. Statistically significant increase in the signal intensity and standard deviation from the mean intensity on T1, T2‑maps of psammomatous meningiomas compared to all other subtypes was observed. Additionally, positive correlation between signal intensity form meningiomas on T1, T2‑maps and intraoperative data on tumor consistency was found.</p></sec><sec><title>Conclusion</title><p>Conclusion. Images obtained using T, T2‑mapping technique are as informative as traditional T2‑weighted images for evaluation of intracranial meningioma consistency. Additionally, they allow to obtain absolute intensity values. Further prospective studies are necessary for confirmation of the obtained results.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>интракраниальные менингиомы</kwd><kwd>магнитно-резонансная томография</kwd><kwd>Т1/Т2‑картирование</kwd><kwd>консистенция менингиом</kwd></kwd-group><kwd-group xml:lang="en"><kwd>intracranial meningiomas</kwd><kwd>magnetic resonance imaging</kwd><kwd>Т1</kwd><kwd>Т2‑mapping</kwd><kwd>meningioma consistency</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">Yao A., Pain M., Balchandani P., Shrivastava R.K.
