Известно, что радиоденсивность по данным компьютерной томографии (КТ), измеренная в единицах Hounsfield (HU), становится все более популярной в оценке свойств костей, в то же время наблюдается ее несоответствие с результатами двухэнергетической рентгеновской денситометрии (DXA).</p><p>Целью исследования явилась оценка взаимосвязей между результатами DXA и КT с акцентом на объяснение наблюдаемых расхождений.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Поперечное исследование, в которое были включены сорок пациентов. Все больные подверглись DXA и КT. Минеральная плотность кости (BMD, г/см2 ) рассчитывали для каждого поясничного позвонка от L1 до L4 включительно и проксимального отдела бедра. Радиоденсивность кости в HU была определена для тела каждого позвонка в сагиттальной, аксиальной и корональной плоскостях. Рассчитывали общую радиоденсивность тела позвонка, включая кортикальную кость, и радиоденсивность только спонгиозной кости. Для оценки потенциального влияния DXA на данные КТ для каждого позвонка измеряли среднюю радиоденсивность, площадь правой и левой ножек и фасеточных суставов.</p></sec><sec><title>Результаты</title><p>Результаты. Установлена значительная корреляция между BMD, измеренной с использованием данных DXA и КТ (r = 0,84169, p &lt; 0,0001), однако наиболее значимыми были параметры, рассчитанные в области фасеточных суставов. Обнаружено, что как радиоденсивность губчатой кости, так и общая радиоденсивность имеют слабую корреляцию с соответствующими измерениями BMD проксимального отдела бедренной кости.</p></sec><sec><title>Заключение</title><p>Заключение. Сильное влияние на результаты DXA могут оказывать гипертрофические изменения фасеточных суставов. Результаты измерений как КТ, так и DXA, выполненных в поясничном отделе позвоночника, могут иметь несоответствия с данными, полученными при изучении проксимального отдела бедра. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. It is reported that radiodensity measured in Hounsfield units becomes more and more popular in bone property assessment, however also mismatch with DXA results is observed.</p></sec><sec><title>Purpose</title><p>Purpose. The aim of this study is to evaluate the relationships between the results of DXA and CT with a focus on explanations for observed discrepancies.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. This is a cross-sectional study; forty patients were enrolled, all patients underwent DXA and CT. A bone mineral density BMD (g/cm2) was calculated for each vertebra of a lumbar spine (L1-L4 inclusive), neck, upper neck, shaft, Wards triangle and trochanter of hip. Bone radiodensity in HU was taken from each vertebral body in the sagittal, axial and coronal planes. A total vertebra body radiodensity including cortical bone and radiodensity of only cancellous bone were calculated. To assess a potential impact on DXA and CT data agreement a mean radiodensity and square of the right and left vertebral pedicles and facet joints were measured for each vertebra.</p></sec><sec><title>Results</title><p>Results. A strong correlation between BMD measured using DXA and CT data was estimated with a multiply r accounting for 0.84169, p &lt; 0.0001, however the most contributing parameters were those calculated for facet joints. It has been detected that both radiodensity of only a cancellous bone and total have a weak correlation with matching BMD measurements of a proximal femur.</p></sec><sec><title>Conclusion</title><p>Conclusion. The results of DXA could be strongly influenced by hypertrophic changes of facet joints. Both CT and DXA measurements taken from a lumbar spine may have a mismatch with figures taken from hip. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>компьютерная томография</kwd><kwd>остеоденситометрия</kwd><kwd>радиоденсивность</kwd><kwd>минеральная плотность костной ткани</kwd></kwd-group><kwd-group xml:lang="en"><kwd>computed tomography</kwd><kwd>osteodensitometry</kwd><kwd>radiodensity</kwd><kwd>bone mineral density</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">Galbusera F, Volkheimer D, Reitmaier S, et al.
