ТЕХНИЧЕСКИЕ ПРИНЦИПЫ И ОСОБЕННОСТИ ВЫПОЛНЕНИЯ КТ-ИССЛЕДОВАНИЙ У БОЛЬНЫХ С ВРОЖДЁННЫМИ АНОМАЛИЯМИ СЕРДЦА
Ключевые слова:
кардиальная КТ; новорождённые; врождённые пороки сердца; лучевая доза; оптимизация протокола; болюс-трекинг; тест-болюс; предоперационная диагностика; сосудистая анатомия сердцаАннотация
МРТ сердца и эхокардиография традиционно являются основными методами визуализации у пациентов с врождёнными пороками сердца (ВПС), однако современные поколения КТ с улучшенным пространственным и временным разрешением значительно расширили возможности КТ-диагностики в этой области. Протокол исследования зависит от предполагаемого порока, перенесённых хирургических вмешательств, возраста и кооперации пациента, при этом особенно важно использование стратегий снижения лучевой нагрузки у детей. Для анализа ВПС широко применяется последовательный сегментарный подход, а точная интерпретация требует от радиолога глубокого знания специализированных КТ-протоколов, сложной анатомии и морфологии ВПС, а также понимания принципов хирургической коррекции.
