Из них у 83 алгоритмом ИИ и экспертами была измерена рентгеновская плотность (РП) тел позвонков на уровне Th11-L3 (205 позвонков). Для перевода РП (HU) в МПК применялась разработанная ранее методика ККТ ФК (Количественная компьютерная томография фантом калиевый) с построением калибровочных прямых для семи 64-срезовых КТ сканеров. После проведения калибровки были выполнены и обработаны алгоритмом ИИ КТ ОГК 1853 пациентов в соотношении мужчин и женщин составило 718/1135.</p></sec><sec><title>Результаты</title><p>Результаты: В ходе оценки эффективности алгоритма ИИ получено хорошее соответствие при сравнении измерений МПК по данным экспертов и алгоритма ИИ. Коэффициент детерминации составил R2= 0,945 для отдельных позвонков (Th11-L3) и 0,943 для пациентов (р=0,000). При разделении пациентов из тестовой выборки на группы с/без КП по данным РП были получены сходные показатели ROC AUC для экспертной разметки 0,880 и по данным алгоритма ИИ 0,875. При калибровке КТ сканеров с помощью фантома, содержащего образцы МПК на основе гидрофосфата калия, получена усредненная формула зависимости МПК=0,77*HU-1,343. С учетом критериев American College Radiology для остеопороза граничное значение МПК&lt;80 мг/мл составило 105,6HU для остеопении МПК&lt;120 мг/мл – 157,6HU. При оппортунистическом определении МПК у пациентов старше 50 лет по данным алгоритма ИИ было установлено, что остеопороз выявлен у 31,72% женщин и 18,66% мужчин.</p></sec><sec><title>Вывод</title><p>Вывод: Продемонстрирована хорошая сопоставимость результатов определения РП тел позвонков по данным морфометрического алгоритма ИИ и при экспертной разметке. Предложена методика и продемонстрирована эффективность оппортунистического определения МПК тел позвонков по данным КТ с помощью алгоритма ИИ и использования фантомного моделирования.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Goal</title><p>Goal: To develop a method for automated assessment of the volumetric bone mineral density (BMD) of the vertebral bodies using an artificial intelligence (AI) algorithm and a phantom modeling method.</p></sec><sec><title>Materials and Methods</title><p>Materials and Methods: Evaluation of the effectiveness of the AI algorithm designed to assess BMD of the vertebral bodies based on chest CT data. The test data set contains 100 patients aged over 50 y.o.; the ratio between the subjects with/without compression fractures (Сfr) is 48/52. The X-ray density (XRD) of vertebral bodies at T11-L3 was measured by experts and the AI algorithm for 83 patients (205 vertebrae). We used a recently developed QCT PK (Quantitative Computed Tomography Phantom Kalium) method to convert XRD into BMD followed by building calibration lines for seven 64-slice CT scanners. Images were taken from 1853 patients and then processed by the AI algorithm after the calibration. The male to female ratio was 718/1135.</p></sec><sec><title>Results</title><p>Results: The experts and the AI algorithm reached a strong agreement when comparing the measurements of the XRD. The coefficient of determination was R2=0.945 for individual vertebrae (T11-L3) and 0.943 for patients (p=0.000). Once the subjects from the test sample had been separated into groups with/without Сfr, the XRD data yielded similar ROC AUC values for both the experts – 0.880, and the AI algorithm – 0.875. When calibrating CT scanners using a phantom containing BMD samples made of potassium hydrogen phosphate, the following averaged dependence formula BMD =0.77*HU-1.343 was obtained. Taking into account the American College Radiology criteria for osteoporosis, the cut-off value of BMD&lt;80 mg/ml was 105.6HU; for osteopenia BMD&lt;120 mg/ml was 157.6HU. During the opportunistic assessment of BMD in patients aged above 50 years using the AI algorithm, osteoporosis was detected in 31.72% of female and 18.66% of male subjects.</p></sec><sec><title>Conclusions</title><p>Conclusions: This paper demonstrates good comparability for the measurements of the vertebral bodies’ XRD performed by the AI morphometric algorithm and the experts. We presented a method and demonstrated great effectiveness of opportunistic assessment of vertebral bodies’ BMD based on computed tomography data using the AI algorithm and the phantom modeling.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>минеральная плотность кости</kwd><kwd>искусственный интеллект</kwd><kwd>количественная компьютерная томография</kwd><kwd>остеопороз</kwd><kwd>КТ-денситометрия.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bone mineral density</kwd><kwd>artificial intelligence</kwd><kwd>quantitative computed tomography</kwd><kwd>osteoporosis</kwd><kwd>CT densitometry</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">Белая Ж.Е., Белова К.Ю., Бирюкова Е.В. и др.
