Целью является выявление взаимозаменяемых параметров и оптимизация предоперационной диагностики раздельной функции почек. Материалы и методы. В исследование включены 54 донора почек (108 почек). Для оценки раздельной функции использовались радионуклидная нефросцинтиграфия с 99mTc-меркаптоацетилтриглицином (MAG3) и объемная ПКТ с контрастированием. Оценивались ключевые параметры нефросцинтиграфии: почечный плазмоток (RPF), время максимального накопления препарата (Tmax) и время полувыведения (T½). ПКТ-анализ включал показатели артериального потока (AF), объема крови (BV), фракции экстракции (FE) и индексированной фракции экстракции (IFE). Корреляция между методами оценивалась с использованием коэффициента Пирсона и анализа Бланда–Альтмана. Результаты. Выявлены значимые корреляции между показателями нефросцинтиграфии и ПКТ. Установлена высокая отрицательная корреляция между Tmax и AF (r = –0,75, p &lt; 0,001), что подтверждает связь скорости кровотока с фильтрационной способностью почек. Отрицательная корреляция между T½ и FE (r = –0,75, p &lt; 0,01) указывает на зависимость времени полувыведения препарата от фракции экстракции. Высокая положительная корреляция между RPF и IFE (r = 0,79, p &lt; 0,001) подтверждает возможность использования индексированных параметров ПКТ для оценки почечного плазмотока. Анализ Бланда–Альтмана показал, что расхождения между методами не превышают клинически значимых пределов, что подтверждает их взаимозаменяемость. Заключение. Результаты исследования демонстрируют возможность частичной взаимозаменяемости нефросцинтиграфии и объемной ПКТ при предоперационной оценке доноров почек. ПКТ обеспечивает более точную оценку почечного кровотока, тогда как нефросцинтиграфия остается предпочтительным методом для анализа экскреторной функции. Совместное использование данных методов позволяет повысить точность диагностики и улучшить отбор доноров почек, обеспечивая безопасность трансплантационной программы.</p></abstract><trans-abstract xml:lang="en"><p>Objective: to evaluate the correlation between renal scan (RSc) and volumetric multislice computed tomography (perfusion CT) in living kidney donors, with the goal of identifying interchangeable functional parameters and optimizing the preoperative assessment of split renal function. Materials and methods. The study included 54 living kidney donors (totaling 108 kidneys). Split renal function was assessed using RSc with 99mTc-mercaptoacetyltriglycine (MAG3) and contrast-enhanced volumetric MSCT. Key parameters from nephroscintigraphy included renal plasma flow (RPF), time to maximum tracer accumulation (Tmax), and excretion half-life (T½). Single-photon emission computed tomography (SPECT) analysis included arterial flow (AF), blood volume (BV), extraction fraction (FE), and indexed extraction fraction (IFE). Correlation between modalities was analyzed using Pearson’s correlation coefficient and Bland–Altman plots. Results. Significant correlations were observed between RSc and volumetric MCT parameters. A strong negative correlation was found between Tmax and AF (r = –0.75, p &lt; 0.001), indicating an inverse relationship between blood flow velocity and renal filtration capacity. Similarly, T½ showed a negative correlation with FE (r = –0.75, p &lt; 0.01), suggesting that a shorter tracer half-life corresponds to more efficient renal extraction. A strong positive correlation between RPF and IFE (r = 0.79, p &lt; 0.001) supports the feasibility of using indexed CT perfusion as a surrogate for assessing RPF. Bland-Altman analysis showed that differences between the two diagnostic methods remained within clinically acceptable limits, confirming their potential interchangeability in preoperative donor assessment. Conclusion. The study demonstrates the potential for partial interchangeability between RSc and volumetric CT perfusion in the preoperative assessment of kidney donors. While CT perfusion offers superior accuracy in assessing renal blood flow, nephroscintigraphy remains the method of choice for evaluating excretory function. The combined use of both modalities improves diagnostic accuracy and kidney donor selection, thereby improving the safety of kidney transplant programs.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>раздельная функция почек</kwd><kwd>нефросцинтиграфия</kwd><kwd>объемная КТ-перфузия</kwd><kwd>донорство почки</kwd><kwd>почечная перфузия</kwd><kwd>функциональная диагностика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>split renal function</kwd><kwd>nephroscintigraphy</kwd><kwd>volumetric CT perfusion</kwd><kwd>kidney donation</kwd><kwd>renal perfusion</kwd><kwd>functional diagnostics</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">Grenier N, Basseau F.
