Провели эксцизионную биопсию поражения из этой же анатомической зоны и определили клеточность в гистологическом материале.</p></sec><sec><title>Результаты</title><p>Результаты. При ЛХ, агрессивных НХЛ и диффузной В-крупноклеточной лимфоме (ДВКЛ) ИКД статистически значимо выше, а клеточность ниже, чем при индолентных и из клеток мантийной зоны НХЛ. Установлена обратная корреляция значений ИКД и клеточности при агрессивных НХЛ (ρ= -0,47, р = 0,005) и ДВКЛ (ρ = -0,48, р = 0,006).</p></sec><sec><title>Заключение</title><p>Заключение. Значения ИКД зависят от клеточной структуры лимфом. Сопоставление ИКД и клеточности различных морфологических вариантов лимфом позволяет объяснить прогностические свойства ИКД.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to evaluate the correlation between the values of the magnetic resonance imaging (MRI) apparent diffusion coefﬁcient (ADC) and the count of cellularity in histological material and to establish a relationship between the cellular structure and the prognostic properties of MRI with diffusion-weighted imaging (MRIDWI) in various morphological types of lymphomas.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. 101 patients with morphologically veriﬁed lymphoma (Hodgkin lymphoma (HL) — 52 patients, non-Hodgkin lymphomas (NHL) — 49) underwent whole body MRI-DWI before treatment and ADC measurement in the target lesion. An excisional biopsy of the lesion was performed from the same anatomical area and the count of cellularity in the histological material was determined.</p></sec><sec><title>Results</title><p>Results. In HL, aggressive NHL and diffuse large B-cell lymphoma (DLBCL), ADC is statistically signiﬁcantly higher, and cellularity is lower than in indolent NHL and cells of the mantle zone of NHL. We have found an inverse correlation between the values of ADC and cellularity in aggressive NHL (ρ = -0.47, p = 0.005) and DLBCL (ρ = -0.48, p = 0.006).</p></sec><sec><title>Conclusion</title><p>Conclusion. ADC values depend on the cellular structure of the lymphomas. The correlation of ADC and cellularity values of various morphological types of lymphomas allows explaining the prognostic properties of ADC.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>лимфома Ходжкина</kwd><kwd>неходжкинская лимфома</kwd><kwd>магнитно-резонансная томография</kwd><kwd>диффузионно-взвешенное исследование</kwd><kwd>измеряемый коэффициент диффузии</kwd><kwd>клеточность</kwd><kwd>прогнозирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Hodgkin lymphoma</kwd><kwd>non-Hodgkin lymphoma</kwd><kwd>magnetic resonance imaging</kwd><kwd>diffusion-weighted imaging</kwd><kwd>apparent diffusion coefﬁcient</kwd><kwd>cellularity</kwd><kwd>prediction</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">ГНТП «Новые методы оказания медицинской помощи» (задание 02.09).</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">Хоружик СА, Жаврид ЭА, Дзюбан АВ и др.
