Визуализируя наше дыхание: ксенон улучшит качество МРТ

В НИИЭФА создали инновационную технологию и оборудование для получения гиперполяризованного ксенона‑129. Разработка поможет улучшить качество МРТ легких.

▪️Что за технология?

Впервые в России создан полномасштабный экспериментальный образец поляризатора — инструмента, который позволит внедрить ксеноновую томографию в медицину.

▪️Какая польза?

Гиперполяризованный ксенон‑129 позволяет увеличить контраст изображения МРТ в 100 тыс. раз. Ксеноновая МРТ поможет в борьбе с такими опасными заболеваниями, как хроническая обструктивная болезнь легких, астма, муковисцидоз, эмфизема легких, фиброз легочных тканей.

▪️Зачем нужна разработка?

Принцип действия МРТ основан на регистрации энергии протонов. Органы, наполненные воздухом (легкие, кишечник, желудок) и постоянно двигающиеся, на снимках отображаются менее четко. Это в первую очередь связано с низкой плотностью протонов (ядер водорода) во вдыхаемом воздухе. Контрастный агент в виде гиперполяризованных благородных газов значительно повышает поляризацию протонов, а значит, и качество МРТ легких. Предпочтителен 129‑й изотоп ксенона: он хорошо растворяется в тканях.

▪️Суть метода?

Пациент в тоннеле томографа вдыхает примерно литр смеси гиперполяризованного ксенона‑129 с азотом, затем происходит короткое (15–20 секунд) сканирование. Оно выявляет области легкого, в которых отсутствует или затруднен газовый обмен.

Telegram and Signal Havens for Right-Wing Extremists

Since the violent storming of Capitol Hill and subsequent ban of former U.S. President Donald Trump from Facebook and Twitter, the removal of Parler from Amazon’s servers, and the de-platforming of incendiary right-wing content, messaging services Telegram and Signal have seen a deluge of new users. In January alone, Telegram reported 90 million new accounts. Its founder, Pavel Durov, described this as “the largest digital migration in human history.” Signal reportedly doubled its user base to 40 million people and became the most downloaded app in 70 countries. The two services rely on encryption to protect the privacy of user communication, which has made them popular with protesters seeking to conceal their identities against repressive governments in places like Belarus, Hong Kong, and Iran. But the same encryption technology has also made them a favored communication tool for criminals and terrorist groups, including al Qaeda and the Islamic State.
