В проспективное исследование было включено 29 пациентов (м/ж –  16/13, средний возраст 57,6 ± 2,1 годы) с хроническими инфарктами миокарда в анамнезе.  Протокол КТ состоял из ангиографической (20 с) фазы и отсроченных последовательностей  на 8-й минуте после введения контрастного препарата. Все исследования проводились на  однотрубочном двухэнергетическом 64-рядном компьютерном томографе (Discovery 850, GE, США) в двухэнергетическом режиме (GSI). КТ-изобра жения были визуально проанализированы на наличие дефектов перфузии и отсроченного  контрастирования миокарда двумя независимыми исследователями в сравнении с МРТ. Чувствительность, специфичность, диагностическая точность, нормализованное  соотношение концентрации йода в нормальном и рубцово-измененном миокарде были рассчитаны для обоих методов.</p></sec><sec><title>Результаты</title><p>Результаты. Чувствительность, специфичность, диагностическая точность при сравнении с  отсроченными последовательностями МРТ в определении рубцовоизмененных сегментов для ДЭКТ в артериальную фазу составила 95, 90, 95%, для ДЭКТ в отсроченную фазу96, 88, 99% соответственно. Значимой разницы между показателями чувствительности,  специфичности, диагностической точности ДЭКТ в артериальную и отсроченную фазы  выявлено не было (p = 0,32). Однако качество изображений и соотношение  нормализованной концентрации йода в нормальном и рубцово-измененном миокарде были значимо выше для отсроченной фазы (p &lt; 0,0001).</p></sec><sec><title>Выводы</title><p>Выводы. ДЭКТ в артериальную и отсроченную фазы контрастирования имеет высокую  диагностическую точность в сравнении с отсроченным контрастированием при МРТ.  Диагностическая значимость ДЭКТ при отсроченном контрастировании была несколько  выше, чем при ДЭКТ в артериальную фазу.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose</title><p>Purpose. To compare the performance of static myocardialDECT perfusion imaging (CTA) with DECT delayed enhancement for  detection of ischemic myocardial scars using LGE MRI as a diagnostic standard.</p></sec><sec><title>Materials and Methods</title><p>Materials and Methods. 29 patients (m/f –16/13 mean age 57.6 ± 2.1) with chronic myocardial infarction were prospectively enrolled in the study. The CCTA protocol consisted of prospectively gated static myocardial DECT perfusion imaging (angiographic phase) and DECT delayed enhancement with 8 min delay after contrast media injection. Study was performed with 64-row single-source dual energy CT with fast kilovoltage switching. DECT images were visually assessed for first-pass arterial enhancement deficit and delayed enhancement using iodine distribution maps by 2 observers in comparison with LGE MRI. Sensitivity and specificity, the normalized iodine concentration ratio of normal myocardium and scar tissue were calculated both for both methods.</p></sec><sec><title>Results</title><p>Results. For scar detection static myocardial DECT perfusion had  accuracy, sensitivity and specificity 95%, 90%, 95%, resp. vs.  delayed DECT – 96%, 88%, 99%, resp. There was no significant  difference between accuracy, sensitivity and specificity for DECT  perfusion and delayed DECT (p = 0.32). However diagnostic  confidence and normalized iodine concentration ratio of normal  myocardium and scar for static myocardial DECT perfusion were  significantly lower than for delayed DECT (p &lt; 0.0001).</p></sec><sec><title>Conclusion</title><p>Conclusion. DECT CTA and DECT delayed enhancement have a  good accuracy for detection of post-infarction scars in comparison  with LGE MRI. The overall diagnostic performance of DECT delayed  enhancement was better then of static myocardial DECT perfusion  imaging. Thus, delayed sequences should not be omitted from CTA  standard protocol if the aim is myocardial scar detection.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>двухэнергетическая КТ (ДЭКТ)</kwd><kwd>рубцы миокарда</kwd><kwd>статическая ДЭКТ-перфузия</kwd><kwd>отсроченное контрастирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Dual-Energy CT</kwd><kwd>myocardial scar</kwd><kwd>DECTperfusion</kwd><kwd>DECT delayed enhancement</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">Грамович В.В., Синицын В.Е.
