Количественная компьютерная томография (ККТ) с асинхронной калибровкой не требует фантома при сканировании пациента. На основе данных калибровки этот метод преобразует рентгенов- скую плотность (HU) в минеральную плотность кости (МПК). Учитывая большое количество КТ-исследований, проводимых у пациентов с риском остеопороза, существует потребность в практичном методе, позволяющем оценить МПК за короткий период времени без специального программного обеспечения.</p></sec><sec><title>Цель</title><p>Цель. Разработать метод денситометрии кости QCT с использованием фантома РСК ФК2, сравнить измерения разработанного метода и результатами QCT с асинхронной калибровкой с использованием программного обеспечения от известного производителя.</p></sec><sec><title>Методы</title><p>Методы. Исследования проводились на 64-срезовом КТ-сканере. МПК измеряли с использованием двух методов: 1) QCT с асинхронной калибровкой с использованием программного обеспечения от известного производителя; 2) QCT-ФК с использованием фантома РСК ФК2 (Разработка средств измерения, фантом калиевый вторая модификация). Для преобразования HU в значения МПК мы сканировали фантом РСК ФК2 и рассчитывали поправочный коэффициент. Фантом содержит “позвонки”, заполненные гидрофосфатом калия в разных концентрациях. В обоих методах значения BMD измеряли для позвонков LI–II (в ряде наблюдений для ThXII, LIII).</p></sec><sec><title>Результаты</title><p>Результаты. В исследование было включено 65 человек (11 мужчин и 54 женщины); медиана возраста 69,0 года Q1 60 лет, Q3 71 год. Сравнение МПК позвонков, измеренное с помощью методов QCT и QCT-ФК, выявило значимую линейную корреляцию Пирсона r = 0,977 (p &lt; 0,05). Анализ по Бленду–Альтману показал отсутствие связи между разницей в измерениях показателях и средней BMD, также было отмечено достоверное систематическое смещение BMD +4,50 мг/мл в QCT по сравнению с QCT-ФК. С использованием непараметрического критерия Уилкоксона было показано, что различия в разбиении на группы: остео- пороз / остеопения / норма по критериям ACR (American College Radiology) для двух методов было недостоверным.</p></sec><sec><title>Вывод</title><p>Вывод. Разработанный асинхронный метод QCT-ФК измеряет МПК сравнимо с широко используемым методом QCT с асинхронной калибровкой. Этот метод может использоваться для оппортунистического скрининга остеопороза.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Rationale</title><p>Rationale. Quantitative CT (QCT) bone densitometry with asynchronous calibration not require a phantom during the scan procedure. Based on calibration data it converts X-ray density in HU to bone mineral density (BMD). Given the large number of CT studies performed on patients at risk of osteoporosis, there is a need for a hands-on method capable of assessing BMD in a short period of time without tailored software or protocols.</p></sec><sec><title>Goal</title><p>Goal. To develop a method for QCT bone densitometry using an PHK (PHantom Kalium), to compare the volume BMD measurements with the QCT data with asynchronous calibration provided by software from a reputable developer.</p></sec><sec><title>Methods</title><p>Methods. The studies were performed at 64-slice CT unit with body scanning parameters. The BMD was measured using two techniques: 1) QCT with asynchronous calibration using software from a reputable developer; 2) QCT using a PHK phantom (QCT-PHK). For convert the HU to BMD values, we scanned the PHK phantom and calculate correction factor. Phantom contains “vertebrae” filled with potassium hydrogen phosphate in different concentrations. In both methods, the BMD values measured for LI–II, and sometimes for ThXII, LIII.</p></sec><sec><title>Results</title><p>Results. The study enrolled 65 subjects (11 male and 54 female patients); median age 69.0 years. A comparison of the vertebrae BMD measured by QCT and QCT-PHK revealed a significant linear Pearson correlation r = 0.977 (p &lt; 0.05). The Bland–Altman analysis demonstrated a lack of relationship between the difference in measurements and the average BMD and a systematic BMD; bias of +4.50 mg/ml in QCT vs. QCT-PHK. Differences in the division into groups osteoporosis / osteopenia / norm according to the ACR criteria for the two methods were not significant.</p></sec><sec><title>Conclusion</title><p>Conclusion. The developed asynchronous QCT-PHK method measure BMD comparable to the widely used QCT with asynchronous calibration. This method can be used for opportunistic screening for osteoporosis.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>количественная компьютерная томография</kwd><kwd>ККТ</kwd><kwd>оппортунистический скрининг остеопороза</kwd><kwd>минеральная плотность кости</kwd><kwd>МПК</kwd><kwd>фантомное моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>quantitative computed tomography</kwd><kwd>QCT</kwd><kwd>opportunistic screening for</kwd><kwd>bone mineral density</kwd><kwd>BMD</kwd><kwd>phantom study</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Engelke K.
