Оценить взаимосвязь между степенью стеатоза печени, количественно определенной по среднепеченочному значению протонной плотности жировой фракции при магнитно-резонансной томографии (МРТ), и индексом массы тела (ИМТ) обследованных пациентов.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведено ретроспективное обсервационное исследование, включившее 776 пациентов, которым выполнена мультипараметрическая магнитно-резонансная томография органов брюшной полости на томографах Magnetom Vida (Siemens) 3 Тл и Ingenia Ambition S (Philips) 1,5 Тл. ИМТ рассчитывали по стандартной формуле и рассматривали как системный антропометрический показатель ожирения. Количественную оценку стеатоза печени выполняли по среднепеченочному значению протонной плотности жировой фракции. Степень стеатоза классифицировали какS 0-S3. Для анализа использовали непараметрические методы статистики, корреляционный анализ Спирмена, межгрупповые сравнения с коррекцией множественных сравнений по методу Benjamini-Hochberg и ROC-анализ.</p></sec><sec><title>Результаты</title><p>Результаты. Выявлена статистически значимая положительная корреляция между протонной плотностью жировой фракции печени и ИМТ (р=0,569; p&lt;0,001). При этом при одинаковых значениях ИМТ отмечался широкий диапазон значений протонной плотности жировой фракции с выраженным перекрытием между степенями стеатоза. Стеатоз печени был выявлен у 9% пациентов с ИМТ &lt;25 кг/м2, тогда как у 36% пациентов с ИМТ &gt;30 кг/м2признаки стеатоза отсутствовали. Площадь под ROC-кривой ИМТсоставила 0,793 для выявления стеатоза &gt;S 1, 0,761 для &gt;S2 и 0,706 для &gt;S3, что соответствует умеренной и низкой дискриминирующей способности показателя.</p></sec><sec><title>Заключение</title><p>Заключение. ИМТ статистически ассоциирован с выраженностью стеатоза печени, однако характеризуется высокой вариабельностью и выраженным перекрытием распределений между степенями стеатоза. Наличие стеатоза печени у 9 % пациентов при нормальном ИМТ и его отсутствие у 36 % пациентов с ожирением отражают ограниченную диагностическую ценность ИМТ для оценки степени жировой инфильтрации печени. Количественная оценка протонной плотности жировой фракции при МРТ обеспечивает объективную и воспроизводимую характеристику стеатоза печени независимо от категории ИМТ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose</title><p>Purpose. To evaluate the association between the severity of hepatic steatosis, quantitatively determined by the mean whole-liver proton density fat fraction on magnetic resonance imaging (MRI), and body mass index (BMI) in the examined patients.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A retrospective observational study included 776 patients who underwent multiparametric abdominal magnetic resonance imaging on Magnetom Vida (Siemens) 3 T and Ingenia Ambition S (Philips) 1.5 T scanners. BMI was calculated using the standard formula and considered a systemic anthropometric indicator of obesity. Quantitative assessment of hepatic steatosis was performed using the mean whole-liver proton density fat fraction. Steatosis severity was classified as S 0-S 3. Nonparametric statistical methods were used, including Spearman correlation analysis, intergroup comparisons with Benjamini-Hochberg correction for multiple testing, and ROC analysis.</p></sec><sec><title>Results</title><p>Results. A statistically significant positive correlation was found between hepatic proton density fat fraction and BMI (p=0.569; p&lt;0.001). At the same time, for identical BMI values, a wide range of proton density fat fraction values was observed, with substantial overlap between steatosis grades. Hepatic steatosis was detected in 9 % of patients with BMI &lt;25 kg/m2, whereas 36 % of patients with BMI &gt;30 kg/m2 had no signs of steatosis. The area under the ROC curve for BMI was 0.793 for detecting steatosis &gt;S 1, 0.761 for &gt;S 2, and 0.706 for &gt;S 3, corresponding to moderate to low discriminative performance.</p></sec><sec><title>Conclusion</title><p>Conclusion. BMI is statistically associated with the severity of hepatic steatosis but demonstrates high variability and pronounced overlap between steatosis grades. The presence of hepatic steatosis in 9 % of patients with normal BMI and its absence in 36 % of patients with obesity reflect the limited diagnostic value of BMI for assessing the degree of hepatic fat infiltration. Quantitative assessment of proton density fat fraction by MRI provides an objective and reproducible characterization of hepatic steatosis regardless of BMI category.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>индекс массы тела</kwd><kwd>стеатоз печени</kwd><kwd>протонная плотность жировой фракции</kwd><kwd>магнитно-резонансная томография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>body mass index</kwd><kwd>liver steatosis</kwd><kwd>proton density fat fraction</kwd><kwd>magnetic resonance imaging</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">Feng G., Targher G., Byrne C.
