КОМПЬЮТЕРНАЯ ТОМОГРАФИЯ С ИСПОЛЬЗОВАНИЕМ МОДЕЛЬ-БАЗИРОВАННЫХ ИТЕРАТИВНЫХ РЕКОНСТРУКЦИЙ В КЛИНИЧЕСКОЙ ПРАКТИКЕ

В связи с широким внедрением КТ в клиническую практику вопрос о снижении дозы облучения остается одним из самых насущных. Одним из направлений снижения лучевой нагрузки является совершенствование алгоритмов реконструкции КТ-изображений. При использовании модельной интерактивной реконструкции изображения многократно  обрабатываются для максимального устранения цифрового шума, что позволяет выполнять низкодозовые исследования без снижения качества визуализации. В обзоре литературы представлены возможности применения модельной итеративной реконструкции при КТ-исследовании различных органов и систем, в том числе при низкодозовых исследованиях с дозой облучения менее 1 мЗв, оценка качества выполненных исследований и визуализации патологии различных органов и систем. Наиболее востребованной новая методика является для скрининговых исследований, например, для НДКТ-скрининга рака легкого, и исследований, в которых требуется высокое разрешение, например, для КТ- коронарографии.
