Всем пациентам выполнены МР-энтероколонография с внутривенным контрастированием и колоноилеоскопия. При МР-энтероколонографии оценивалась активность воспалительного процесса в толстой и тонкой кишке (в общей сложности в 406 сегментах) с применением индекса MaRIAs (сегментарный). Данные МРТ сопоставлены с выраженностью воспаления в 406 сегментах при эндоскопическом исследовании.</p></sec><sec><title>Результаты</title><p>Результаты: при эндоскопическом исследовании в 71 (71/406, 17,5%) сегменте не было выявлено признаков воспалительной активности; в 168 (168/406, 41,3%) сегментах отмечены эндоскопические признаки незначительно или умеренно выраженной активности, в 167 (167/406, 41,2%) сегментах обнаружена выраженная активность воспалительного процесса с наличием язв. При МР-энтероколонографии не выявлено каких-либо изменений в 121 (121/406, 29,8%) сегменте (0 баллов по индексу MaRIAs), в 285 (285/406, 70,2%) сегментах диагностирована активность воспалительного процесса, оцененная по индексу MaRIAs от 1 до 5 баллов. Отмечена средняя степень согласованности (Cohen’s Kappa: 0.57) между данными МР-энтероколонографии и колоноилеоскопии в определении пораженных сегментов. При проведении ROCанализа установлено, что при величине индекса MaRIAs (сегментарный) в 1 балл и более с чувствительностью 82% и специфичностью 92% (AUC 0,85) можно судить о наличии активности воспаления любой выраженности, а при величине индекса 2 балла и более с чувствительностью 75% и специфичностью 91% (AUC 0,91) можно говорить о выраженном воспалении с наличием язв.</p></sec><sec><title>Заключение</title><p>Заключение: полученные результаты по определению активности воспаления в тонкой и толстой кишке с применением индекса MaRIAs (сегментарный) у пациентов с болезнью Крона делают целесообразным продолжение исследования с изучением диагностической эффективности индекса MaRIAs (общий) с целью применения его для оценки эффективности консервативного лечения пациентов с болезнью Крона.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim: to evaluate diagnostic value of magnetic resonance enterocolonography (MR-enterocolonography) with the use of the segmental index MaRIAs (Simplified Magnetic Resonance Index of Activity) for inflammation activity in small and large intestine colon compared with ileocolonoscopy.</p></sec><sec><title>Patients and Methods</title><p>Patients and Methods: the prospective cohort study included 58 patients with Crohn’s disease aged 19–45 years. All patients underwent MR-enterocolonography with intravenous contrast and ileocolonoscopy. MR-enterocolonography assessed inflammatory activity in the large and small intestine (406 segments) using the MaRIAs index (segmental). MRI data were compared with ileocolonoscopy.</p></sec><sec><title>Results</title><p>Results: ileocolonoscopy showed no signs of inflammatory activity in 71 (71/406, 17.5%) segments. In 168 (168/406, 41.3%) segments endoscopic signs of low or moderate inflammatory activity were detected, in 167 (167/406, 41.2%) segments inflammatory activity with the presence of ulcers were detected. MR-enterocolonography did not detect any activity in 121 (121/406, 29.8%) segments (0 points by MaRIAs index), in 285 (285/406, 70.2%) segments, the inflammation activity was revealed by MaRIAs index from 1 to 5 points. There was a moderate agreement (Cohen’s Kappa: 0.57) between the data of MR-enterocolonography and ileocolonoscopy in detection of affected segments. ROC analysis revealed that with the value of the MaRIAs index (segmental) of 1 point or more with sensitivity of 82.0% and specificity of 92.0% (AUC 0.85), it is possible to consider the presence of inflammatory activity of any severity, and with index value of 2 points or more with sensitivity of 75.0% and specificity of 91.0% (AUC 0.91) can diagnose the severe inflammation with ulcers.</p></sec><sec><title>Conclusion</title><p>Conclusion: the results obtained revealed the value of MaRIAs index and the further study to evaluate the effectiveness of conservative treatment of Crohn’s disease is needed.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>магнитно-резонансная энтероколонография</kwd><kwd>внутривенное контрастирование</kwd><kwd>MaRIAs</kwd><kwd>колоноилеоскопия</kwd><kwd>болезнь Крона</kwd></kwd-group><kwd-group xml:lang="en"><kwd>MR-enterocolonography</kwd><kwd>intravenous contrast</kwd><kwd>MaRIAs</kwd><kwd>ileocolonoscopy</kwd><kwd>Crohn’s disease</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">Rimola J, Rodriguez S, García-Bosch O, et al.
