Проанализированы результаты сцинтиграфии скелета у 1568 пациентов. Сканирование в режиме «все тело» начинали через 3 ч после внутривенного введения радиофармпрепарата (РФП) активностью 740 МБк и проводили в передней и задней проекциях при непрерывном движении стола со скоростью 12 см/мин. При необходимости выполняли досмотр в режиме однофотонной эмиссионной компьютерной томографии с компьютерной томографией.</p></sec><sec><title>Результаты</title><p>Результаты. Очаговые артефакты, констатированные у 40 (2,55%) пациентов, по характеру имитируемых ими изменений костной системы разделены на «холодные» и «горячие». «Холодные» очаги (n = 29) были следствием экранирующего эффекта металлических аксессуаров (10), имплантатов, эндопротезов (18), а также бариевой взвеси в толстом кишечнике (1). «Горячие» очаги» (n = 11) имитировали метастатическое поражение костных структур в результате проекционного эффекта внекостного накопления 99mTc-ПФ (n = 9) или мочевой контаминации (n = 2). «Горячий» очаг в проекции верхнего полюса почки (n = 5) мог быть следствием как каликостаза (n = 3), так и травмы прилежащего ребра (n = 2). Высокий захват 99mTc-ПФ узлом щитовидной железы (n = 3) имитировал «горячий» очаг в боковом отделе шейного позвонка. Аномальное накопление РФП сосковыми зонами удаленной молочной железы проецировалось на задние отрезки ребер. Мочевая контаминация имитировала очаговую патологию костей таза. Дифференцирование очаговой патологии ребер и каликостазов проводилось при досмотре области почек в положении пациента стоя. Для уточнения проекционного соответствия «горячих» очагов использовали программу их «маскировки» (mask in).</p></sec><sec><title>Заключение</title><p>Заключение. Анализ причин формирования очаговых артефактов при сцинтиграфии скелета способствует адекватной оценке полученных данных, позволяет выбрать необходимый методический прием их диагностики, избежать ошибочной интерпретации результатов остеосцинтиграфии.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to clarify and systematize the causes that can induce focal artefacts in skeletal scintigraphy with 99mTc-pyrophosphate (PyP), their semiotics, principles and methods of differentiation from bone pathology.</p></sec><sec><title>Material and methods</title><p>Material and methods. Results of skeletal scintigraphy from 1568 patients were analyzed. Scanning in “whole body” mode started in 3 hours after 740 MBq of radiotracer activity intravenous administration, and performed in anterior and posterior projections in continuous table motion mode at rate of 12 cm per minute. Single photon emission computed tomography/computed tomography was additionally performed when necessary.</p></sec><sec><title>Results</title><p>Results. Focal artifacts were detected in 40 patients (2.55%) and were divided into “cold” and “hot” according to the nature of the bone system changes they simulated. “Cold” spots (n = 29) were the result of the shielding effect of metal accessories (n = 10), implants, endoprostheses (n = 18), and barium suspension residues in the large intestine (n = 1). “Hot” spots (n = 11) mimicking metastatic lesion of bone structures were the results of the projection effect of extraosseous uptake of 99mTc-PyP (n = 9) or urinary contamination (n = 2). “Hot” spots in the projection of the upper pole of the kidney (n = 5) could be the result of both calicostasis (n = 3) and injury of the adjacent rib (n = 2). The high uptake of 99mTc-PyP in thyroid nodule (n = 3) simulated a “hot” spot in the lateral part of the cervical vertebra. Abnormal accumulation of 99m Tc-PyP in the nipple-areola areas of the breast was projected onto the posterior segments of the ribs. Urinary contamination imitated focal pathology of the pelvic bones. To differentiate the focal pathology of the ribs and calicostases, the patients were examined in the standing position. The “mask in” program was used to clarify the localization and projection correspondence of “hot” foci.</p></sec><sec><title>Conclusion</title><p>Conclusion. Analysis of focal artefacts formation causes in skeletal scintigraphy contributes to an adequate assessment of the data obtained, allows to choose the necessary method for their diagnosis and to avoid false results of osteoscintigraphy.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>сцинтиграфия скелета</kwd><kwd>99mTc-пирофосфат</kwd><kwd>очаговые артефакты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>skeletal scintigraphy</kwd><kwd>99mTc-pyrophosphate</kwd><kwd>scintigraphic artefacts</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">Тултаев А.В., Корсунский В.Н., Лабушкина А.А., Забелин М.В.
