В период с апреля 2013 по апрель 2019 года в отделе радионуклидной диагностики ФГБУ НМИЦ кардиологии перфузионная ОЭКТ миокарда с КТ-коррекцией поглощения (AC) была выполнена у 3144 пациентов с различной сердечно-сосудистой патологией. На основании полученного опыта были расширены и скорректированы принципы обработки и интерпретации результатов данного исследования, впервые изложенные нами в 2014 году. Основное внимание уделено трактовке апикальных и перегородочных дефектов перфузии, диффузной неравномерности перфузии, демонстрации роли современных алгоритмов реконструкции в получении изображений миокарда максимально высокого качества, оценке самостоятельных возможностей данных низкодозной КТ при проведении ОЭКТ/КТ миокарда, а также предложениям по стандартизации количественных параметров оценки перфузии при ОЭКТ/КТ миокарда.</p></sec><sec><title>Результаты</title><p>Результаты. КТ-коррекция поглощения излучения (AC) в значительной мере влияет на интерпретацию перфузионной ОЭКТ миокарда в большинстве случаев. Появление апикального “дефекта” перфузии на AC-изображениях встречается у 50% пациентов без установленной ИБС и может трактоваться как вариант нормы (апикальное утончение). Диффузная неравномерность накопления перфузионного РФП при использовании современных алгоритмов реконструкции выделяется в отдельный паттерн как признак нарушений микроциркуляции. Данные низкодозной КТ позволяют визуализировать грубую патологию в грудной клетке на уровне исследования и должны быть отражены в заключении. Описания перфузионных исследований, основанные на анализе ACи nAC-изображений, имеют более высокую межоператорскую согласованность, чем основанные на анализе только nAC-изображений (κw=0.915 и 0.809, соответственно, p=0.027). При этом использование средних арифметических значений площади преходящей ишемии (Reversibility Extent) лучше согласуется с визуальным анализом (Δ=0.08Ѓ}1.46%, p=0.49)</p></sec><sec><title>Заключение</title><p>Заключение. Выполнение КТ-коррекции и использование современных итеративных алгоритмов при проведении перфузионной ОЭКТ миокарда должно быть частью обязательного протокола исследования, поскольку это в значительной мере влияет на диагностическую ценность метода. Пограничные значения параметров нарушений перфузии при использовании КТ-коррекции должны быть пересмотрены.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to investigate the possibilities of a combined single photon emission computed tomography/computed tomography (SPECT/CT) system during myocardial perfusion studies and to examine the features of their interpretation.</p></sec><sec><title>Subjects and methods</title><p>Subjects and methods. In April 2013 to April 2019, the Department of Radionuclide Diagnosis, National Medical Research Center of Cardiology, performed myocardial perfusion SPECT with attenuation correction (AC) in 3144 patients with various cardiovascular diseases. Based on the experience gained, the authors expanded and adjusted the principles of processing and interpreting the results of this study, which they had first set forth in 2014. Special emphasis is placed on the interpretation of apical and septal perfusion defects and diffuse perfusion irregularity, on the demonstration of the role of current reconstruction algorithms in obtaining highest-quality myocardial images, and on the assessment of self-potentialities of lowdose CT findings at myocardial SPECT/CT, as well as on proposals to standardize quantitative parameters for perfusion assessment at myocardial SPECT/CT.</p></sec><sec><title>Results</title><p>Results. AC affected in large measure the interpretation of myocardial perfusion SPECT in most cases. Apical perfusion defect appeared on AC images was observed in 50% of patients without established coronary heart disease and could be interpreted as a normal variant (apical thinning). The diffuse irregularity of perfusion radiopharmaceutical tracer accumulation in the application of the current reconstruction algorithms stood out in a separate pattern as a sign of microcirculatory disturbances. Low-dose CT data allow visualization of a severe thoracic abnormality at imaging and should be reflected in the conclusion. The perfusion study descriptions based on an analysis of AC and nAC images had a greater interoperator consistency than those based on an analysis of only nAC images (w = 0.915 and 0.809, respectively; p = 0.027). At the same time, the use of arithmetic means of the extent of transient ischemia (Reversibility Extent) is better consistent with visual analysis (= 0.08Ѓ}1.46%, p = 0.49).</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ОЭКТ/КТ</kwd><kwd>КТ-коррекция поглощения</kwd><kwd>миокард</kwd></kwd-group><kwd-group xml:lang="en"><kwd>single photon emission computed tomography/computed topography</kwd><kwd>attenuation correction</kwd><kwd>myocardium</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование поддержано грантом Российского фонда фундаментальных исследований (№19-02-00244-а)</funding-statement><funding-statement xml:lang="en">The study was supported by grant from Russian Foundation for Basic Research (№19-02-00244-а)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Verberne H.J., Acampa W., Anagnostopoulos C., Ballinger J., Bengel F., De Bondt P., et al.
