ЧТО ТАКОЕ ПЭТ, ПЭТ/КТ?
ПЭТ
ПЭТ/КТ
Это современный высокочувствительный
метод ядерной диагностики, позволяющий
оценить различные метаболические
процессы, происходящие в органах и тканях.
В основе метода лежит возможность
отслеживать распределение в организме
биологически активных соединений,
меченных позитрон-излучающими
радиоизотопами.
Это позитронно-эмиссионная
томография, совмещенная с
компьютерной томографией – позволяет
при одном исследовании изучить
физиологические и патофизиологические
процессы, а также сопоставить их с
анатомо-топографическими
особенностями строения органов и
тканей.

ИСТОРИЯ МЕТОДА ПЭТ/КТ
Первые изображения работы мозга,
полученные на позитронно-эмиссионном
томографе в августе 1976 года
● Первые попытки конструкторских разработок
ПЭТ-сканеров были сделаны в 1970-е Майклом
Тер-Погосяном. Известен как «отец позитронноэмиссионной томографии»
● Впервые в Институте радиологии США было
получено ПЭТ изображение головного мозга.
● Развитие ПЭТ началось, одновременно с
магнитно-резонансной томографией (МРТ) в
1970-е годы и МРТ была быстро внедрена в
клиническую практику.
● Переворотным в развитии ПЭТ стал 1979г.,
когда ученые синтезировали
(18F)фтордезоксиглюкозу (18F-ФДГ).
● В 2001г. был начат серийный выпуск первого
совмещенного ПЭТ/КТ сканера,
предназначенного для получения так
называемого совмещенного – анатомофункционального изображения.

передовым
ПЭТ томография относится к
методам,
позволяет обнаружить болезнь даже тогда, когда человек не
испытывает никаких симптомов, что позволяет вовремя
провести лечение, повысить шансы на полное выздоровление.

5.

Что показывает ПЭТ?
Обследование ПЭТ позволяет распознать
изменения в организме на клеточном
уровне, провести оценку структур органа,
получить подробную информацию о
патологическом процессе, распознать
опухоли от 5-6 мм и другие нарушения с
наибольшей тщательностью. В
зависимости от исследуемой области и
направления медицины, данный вид
исследования позволяет определить
следующие клинические состояния:
Онкология:
• стадия злокачественности;
• размер и локализация опухоли;
• разновидность образования;
• метастазы и их распространение;
• оценка результатов химиотерапии
или лучевой терапии.
Кардиология:
• области с нарушенным
кровообращением;
• тромбы, закупорки крупных и
мелких сосудов;
• динамика после лечения инфаркта.
Неврология:
• расположение и злокачественность
внутричерепных опухолей;
• эпилептические участки;
• изменения в сосудах.

This is a graph
Understanding
the numbers
Incorporating a graph in your
case report offers several
advantages. It allows for the
clear visualization and concise
representation of data trends,
comparisons, or correlations. By
presenting information in a
visual format, graphs enable
readers to quickly grasp and
interpret complex findings
