Для снижения количества перфузионных исследований головного мозга, интерпретация которых невозможна или может быть выполнена с ошибками, мы ретроспективно проанализировали перфузионные исследования головного мозга за три года, провели анализ выявленных ошибок на этапе сбора данных и на этапе интерпретации исследований.</p><p>Цели и задачи — проанализировать и разделить на группы причины, которые приводили к ограничениям или невозможности оценки перфузии при интерпретации полученных данных, разработать алгоритм действий для снижения количества неинтерпретируемых исследований.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В ходе исследования ретроспективной оценке подверглись 275 КТ и МРТ-исследований с перфузией головного мозга, выполненных в период с 2017 по 2019 г. на 1,5 Т магнитно-резонансном томографе и 32-срезовом компьютерном томографе.</p></sec><sec><title>Результаты</title><p> Результаты. Результатом данного исследования стало лучшее понимание причин наиболее распространенных ошибок при выполнении перфузионных исследований. Анализ причин позволил выделить факторы, влияющие на выполнение исследования и интерпретацию полученных данных.</p></sec><sec><title>Обсуждение</title><p> Обсуждение. Для качественного проведения перфузионного исследования, учитывая многочисленные факторы, влияющие на интерпретацию получаемых данных, необходимо соблюдать ряд условий по планированию и проведению исследования, а также по оценке полученных данных.</p></sec><sec><title>Выводы</title><p>Выводы. Понимание причин, приводящих к ограничениям или невозможности оценки МРТ и КТ перфузионных исследований, соблюдение рекомендаций по планированию и оценке исследований позволяет получать корректные данные и избегать получения неинформативных исследований или исследований, интерпретация которых ограничена.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. To reduce the number of cerebral perfusion studies, the interpretation of which is not possible or can be performed with errors, we retrospectively analyzed cerebral perfusion studies for three years, analyzed the identified errors at the stage of data collection and the stage of study interpretation.</p></sec><sec><title>Aims and objectives</title><p>Aims and objectives: to analyze and divide into groups the reasons that led to limitations or impossibility to assess perfusion during interpretation of the obtained data, to develop an algorithm of actions to reduce the number of uninterpreted studies.</p></sec><sec><title>Materials and Methods</title><p>Materials and Methods. The study retrospectively evaluated 275 CT and MRI brain perfusion studies performed between 2017 and 2019 on 1.5 T MR and 32-slice CT scans.</p></sec><sec><title>Results</title><p>Results. The result of this study was a better understanding of the causes of the most common errors in perfusion studies. Analysis of the causes allowed us to identify factors that affect the performance of the study and the interpretation of the data obtained. Discussion. In order to perform a quality perfusion study, given the many factors affecting the interpretation of the data obtained, a number of conditions on the planning and execution of the study, as well as on the evaluation of the data obtained, must be followed.</p></sec><sec><title>Conclusions</title><p> Conclusions. Understanding the reasons that lead to limitations or inability to evaluate MRI and CT perfusion studies, adhering to guidelines for planning and evaluating studies allows for correct data and avoids obtaining uninformative studies or studies whose interpretation is limited.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>перфузия головного мозга</kwd><kwd>опухоли</kwd><kwd>МРТ-перфузия</kwd><kwd>КТ-перфузия</kwd><kwd>головной мозг</kwd><kwd>ошибки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>brain perfusion</kwd><kwd>MR-perfusion</kwd><kwd>brain</kwd><kwd>tumor</kwd><kwd>CT-perfusion</kwd><kwd>pitfalls</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">Сопоставление информативности МР-перфузии и ПЭТ с [11С] метионином в дифференциации продолженного роста церебральных опухолей и лучевых поражений головного мозга после комбинированного лечения / Ж.
