Проанализировать опыт применения ДЭКТ у пациентов с недифференцированным артритом и поражением осевого скелета в клинической практике.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В ретроспективное исследование было включено 20 пациентов (14 мужчин и 6 женщин), наблюдавшихся в ФГБНУ НИИР им. В. А. Насоновой, которым с диагностической целью была выполнена ДЭКТ. 13 пациентам с недифференцированным артритом была проведена ДЭКТ периферических суставов с целью диагностики подагры; 7 пациентам с установленным диагнозом подагры (на основании классификационных критериев подагры ACR/EULAR 2015 года) – для уточнения генеза поражения осевых суставов и позвоночника. Исследование было выполнено на компьютерном томографе Siemens SOMATOM Definition Flash.</p></sec><sec><title>Результаты</title><p>Результаты. С помощью ДЭКТ у пациентов с недифференцированным артритом у 7 из 13 (54 %) выявлены депозиты кристаллов моноурата натрия (КМУН), что позволило верифицировать им диагноз подагры. Во второй выборке у 6 пациентов из 7 (85 %) выявлены признаки отложения КМУН по ДЭКТ, что объяснило генез имеющихся жалоб. Среди этих 6 пациентов у 1 человека ДЭКТ выявило наличие КМУН и кристаллов пирофосфата кальция в плечевом суставе, что позволило поставить сразу два диагноза – подагра и болезнь депонирования пирофосфата кальция.</p></sec><sec><title>Выводы</title><p>Выводы. ДЭКТ у пациентов с недифференцированным артритом позволяет верифицировать диагноз подагры более чем в половине случаев (54 %). У 85 % пациентов с подагрой и наличием боли в спине и осевых суставах неясного генеза обнаруживаются депозиты уратов по данным ДЭКТ. Данный метод может быть полезным инструментом для выявления микрокристаллического артрита суставов осевого скелета, однако необходимы дальнейшие исследования для внедрения метода в рутинную практику.</p></sec></abstract><trans-abstract xml:lang="en"><p>Dual-energy computed tomography (DECT) is a radiation diagnostic method that is used in rheumatology to verify microcrystalline arthritis, but in Russia this method is little known and the experience of its use is rather scarce.</p><p>Objective of the research. To analyze the experience of using DECT in patients with undifferentiated arthritis and lesions of the axial skeleton in clinical practice.</p><sec><title>Material and Methods</title><p>Material and Methods. The retrospective study included 20 patients (14 men and 6 women) observed at the V. A. Nasonova Research Institute of Rheumatology, who underwent DECT for diagnostic purposes. 13 patients with undifferentiated arthritis underwent DECT of peripheral joints to diagnose gout; 7 patients with an established diagnosis of gout (based on the 2015 ACR/EULAR classification criteria for gout) – to clarify the genesis of lesions to the axial joints and spine. The study was performed on a Siemens SOMATOM Definition Flash computed tomograph.</p></sec><sec><title>Results</title><p>Results. Using DECT in patients with undifferentiated arthritis, deposits of monosodium urate crystals (MSUc) were detected in 7 out of 13 (54 %), which made it possible to verify the diagnosis of gout. In the second sample, 6 out of 7 patients (85 %) showed signs of MSUc deposition on DECT, which explained the genesis of the existing complaints. Among these 6 patients, in 1 person, DECT revealed the presence of MSUc and calcium pyrophosphate crystals in the shoulder joint, which made it possible to make two diagnoses at once – gout and calcium pyrophosphate deposition disease.</p></sec><sec><title>Conclusion</title><p>Conclusion. DECT in patients with undifferentiated arthritis makes it possible to verify the diagnosis of gout in more than half of the cases (54 %). In 85 % of patients with gout and pain in the back and axial joints of unknown origin, urate deposits are detected according to DECT. This method may be a useful tool for identifying microcrystalline arthritis of the axial joints, but further research is needed to implement the method in routine practice.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>подагра</kwd><kwd>недифференцированный артрит</kwd><kwd>двухэнергетическая компьютерная томография</kwd><kwd>ДЭКТ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gout</kwd><kwd>undifferentiated arthritis</kwd><kwd>dual-energy computed tomography</kwd><kwd>DECT</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья подготовлена в рамках государственного задания по теме № АААА-А20–120040190014–8.</funding-statement><funding-statement xml:lang="en">The article was prepared within the framework of a state assignment on topic No. AAAA-A20–120040190014–8.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ambrose J., Hounsfield G.
