Материал и методы. В проспективное исследование включены 82 пациента с ДЗП алкогольной, вирусной, лекарственной, аутоиммунной и смешанной этиологий. Выполняли ультразвуковое (УЗ) исследование органов брюшной полости и почек с допплеровским сканированием сосудов с помощью УЗ-аппарата Apogee 5300 (SIUI, Китай), МРТ органов брюшной полости с бесконтрастной ASL-перфузией почек на томографе Vantage Titan 1.5 Т (Toshiba, Япония). Определяли показатели объемного почечного кровотока (renal blood flow, RBF) при поступлении пациента в стационар и при динамическом наблюдении сроком до 18 мес. Результаты. При обработке данных ASL-перфузии почек установлены нормальные значения RBF (≥ 450 мл/100 г/мин) и значения, позволяющие прогнозировать и диагностировать гепаторенальный синдром (ГРС) (≤ 449 мл/100 г/мин). Выявлена высокая корреляционная связь показателей ASL-перфузии почек и результатов УЗ-допплеровского исследования почек (r = 0,856). Значения параметров диагностической значимости метода бесконтрастной ASL-перфузии почек у пациентов с ДЗП в прогнозировании ГРС при поступлении в стационар составили: чувствительность – 0,83, специфичность – 0,92, точность – 0,87. Разработан алгоритм обследования пациентов с ДЗП с целью ранней диагностики и наблюдения ГРС. Заключение. Бесконтрастная ASL-перфузия почек при МРТ позволяет эффективно прогнозировать, диагностировать и контролировать в динамике повреждение почек у пациентов с ДЗП различного генеза.</p></abstract><trans-abstract xml:lang="en"><p>Objective: to evaluate the potentials of contrast-free renal arterial spin labeling (ASL) perfusion during magnetic resonance imaging (MRI) for the diagnosis and dynamic follow-up of renal lesions in patients with diffuse liver diseases (DLD). Material and methods. The prospective study enrolled 82 patients with various DLD: alcoholic, viral, druginduced, autoimmune and mixed etiology. Ultrasound examination with Doppler abdominal and renal ultrasonography was conducted using Apogee 5300 (SIUI, China); abdominal MRI with contrast-free renal ASL-perfusion was performed using Vantage Titan 1.5 T (Toshiba, Japan). The parameters of renal perfusion (renal blood flow, RBF) were measured when the patients were admitted to the hospital, then during dynamic follow-up for 18 months. Results. Mathematical processing of results revealed normal RBF values (≥ 450 ml/100 g/min) and values associated with hepatorenal syndrome (HRS) (≤ 449 ml/100 g/min). High correlation between renal ASL-perfusion indicators and results of Doppler renal vessels ultrasonography was detected (r = 0,856). The diagnostic effectiveness parameters of contrast-free renal ASL-perfusion were: sensitivity 0.83, specificity 0.92, diagnostic accuracy 0.87. We created the algorithm of DLD patients examination for early HRS diagnosis and follow-up. Conclusion. Contrast-free renal ASL-perfusion is an informative method for predicting, diagnosis and dynamic follow-up of renal lesions in patients with various DLD.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бесконтрастная ASL-перфузия почек</kwd><kwd>гепаторенальный синдром</kwd><kwd>диффузные заболевания печени</kwd></kwd-group><kwd-group xml:lang="en"><kwd>contrast-free renal ASL-perfusion</kwd><kwd>hepatorenal syndrome</kwd><kwd>diffuse liver diseases</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">Perez IC, Bolte FJ, Bigelow W, et al.
