За 2021 г. из базы городской клинической больницы Санкт-Петербурга были ретроспективно отобраны 100 пациентов, которым были проведены бесконтрастная КТ, КТ-ангиография брахиоцефальных артерий и артерий головного мозга, а также КТ-перфузия. У 50 пациентов был подтвержден ишемический инсульт в бассейне средней мозговой артерии. Также в исследование рандомно включены 50 пациентов, у которых данный диагноз был исключен, в том числе на основе динамического наблюдения в рамках дальнейшей клинической оценки и контрольного КТ-исследования головного мозга. Все 100 исследований были проанализированы 21 рентгенологом, которые независимо друг от друга оценивали каждое исследование на наличие КТ-признаков ишемического инсульта. Статистический анализ включал определение коэффициента каппа Флейсса (κ) относительно согласия по каждому признаку ишемического инсульта, специфичности, чувствительности и точности выявления данных изменений.</p></sec><sec><title>Результаты</title><p>Результаты. Стаж работы врачей экстренной нейрорадиологии в Региональном сосудистом центре влияет как на диагностическую эффективность, так и на согласованность в отношении большинства КТ-признаков ишемического инсульта. В то же время стаж не влияет на диагностическую эффективность врачей, не имеющих опыта в оценке инсульта. Как наиболее высокоспецифичный и воспроизводимый признак ишемического инсульта был выявлен симптом гиперденсной средней мозговой артерии, а самым неоднозначным диагностическим признаком оказался симптом сглаженности корковых борозд. При этом все врачи независимо от стажа и опыта работы в ургентной нейрорадиологии склонны к гипердиагностике.</p></sec><sec><title>Заключение</title><p>Заключение. Необходим дальнейший поиск инструментов и решений, способных нивелировать межэкспертную вариативность в отношении оценки КТ-признаков ишемического инсульта, поскольку данная проблема имеет высокую значимость в клинической практике.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. To evaluate the diagnostic accuracy of radiologists with a wide range of experience and training in emergency neuroradiology and other specialty hospitals, as well as the level of inter-experts’ agreement regarding CT signs of ischemic stroke.</p></sec><sec><title>Material and methods</title><p>Material and methods. Our study included a retrospective cohort of 100 patients who underwent NCCT, CT angiography (mCTA) and CT perfusion in St. Petersburg clinical hospital. Fifty patients had confirmed middle cerebral artery ischemic stroke. The study also randomly included fifty patients in whom this diagnosis was excluded, including on the basis of dynamic follow-up as part of further clinical evaluation and follow-up CT scan of the brain. All 100 CT were reviewed by 21 radiologists who independently assessed each study for CT evidence of ischemic stroke. Statistical analysis included the Kappa-Fleiss coefficient ( ) calculation of agreement for each sign of ischemic stroke, specificity, sensitivity, and accuracy of detection of these changes.</p></sec><sec><title>Results</title><p>Results. The staff radiologist’s mean experience in emergency neuroradiology affects both diagnostic performance and consistency for detection of most CT features of ischemic stroke. At the same time, experience does not affect the diagnostic efficiency of radiologists with no experience in stroke assessment. The most highly specific and reproducible sign of ischemic stroke was the hyperdense middle cerebral artery sign, and the most ambiguous diagnostic sign was the gyral effacement. At the same time, all radiologists, regardless of length of service record and experience in emergency neuroradiology, are prone to over-diagnosis.</p></sec><sec><title>Conclusion</title><p>Conclusion. Further search for tools and solutions is needed to level out interexpert variability regarding assessment of ischemic CT signs, since this problem has high clinical importance.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ишемический инсульт</kwd><kwd>компьютерная томография</kwd><kwd>ранние признаки ишемии</kwd><kwd>ASPECTS</kwd><kwd>межэкспертное согласие</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ischemic stroke</kwd><kwd>computed tomography</kwd><kwd>the signs of early ischemia</kwd><kwd>ASPECTS</kwd><kwd>inter-expert agreement</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">Клинические рекомендации “Ишемический инсульт и транзиторная ишемическая атака у взрослых 2021”. https://cr.minzdrav.gov.ru/recomend/171_2</mixed-citation><mixed-citation xml:lang="en">Clinical guidelines.
