Оценить возможности УЗИ с контрастированием в выявлении метастазов в печени в сравнении со стандартным серошкальным B-режимом МАТЕРИАЛЫ И МЕТОДЫ. Проведено УЗИ 18 пациентам с метастазами колоректального рака в печени, с применением контрастного препарата SonoVue (Bracco, Italy). Пациенты были разделены на две группы: первая группа -10 (55 %) пациентов - до начала проведения химиотерапии; вторая группа - 8 (45 %) пациентов - после проведенной ранее химиотерапии со стабилизацией процесса При УЗИ печени с контрастированием оценивался характер контрастного усиления метастазов в трех фазах - артериальной, венозной и отсроченной. РЕЗУЛЬТАТЫ. Произведена оценка характера накопления контраста в метастазах в печени в артериальную фазу. Контрастный препарат накапливался в метастазах в печени гомогенно по всему объему (у 30 % больных из первой группы, у больных из второй группы такое накопление не наблюдалось), только по периферии очагов (у 70 % больных - из первой группы, у 75 % больных - из второй группы), параллельно с интактной паренхимой печени (у 25 % больных - из второй группы). В отсроченной фазе у 4 (22,2 %) из 18 (100 %) пациентов были обнаружены дополнительные метастазы. Была отмечена значительная разница в начале стадий контрастирования между пациентами первой и второй групп. Позднее накопление контраста было характерно для метастазов печени у пациентов второй группы (25,8 сек. от начала введения контраста). Наиболее раннее начало стадии выведения контраста (washout) было характерно для метастазов в печени у пациентов первой группы (42,4 сек. от начала введения контраста). ЗАКЛЮЧЕНИЕ. УЗИ с применением контрастного усиления улучшает визуализацию метастазов в печени, в сравнении с В-режимом Также возможно применять данную методику в оценке эффективности лечения больных колоректальным раком с метастазами в печени, так как отмечается различие в моментах начала стадий накопления и вымывания контраста из очагов.</p></abstract><trans-abstract xml:lang="en"><p>AIM. To evaluate the capability of CEUS in the detection of CRLM in comparison with conventional grayscale B-mode. MATERIALS AND Mffl'HODS. 18 patents with CRLM underwent CEUS using the contrast agent SonoVue (Bracco, Italy). The patients were divided into two groups: the first group - 10 (55 %) patients before to chemotherapy; the second group - 8 (45 %) patients after chemotherapy and stable disease. The enhancement patterns of liver metastases were evaluated during the vascular phases: arterial, venous, and delayed. RESULTS. The enhancement patterns of liver metastases on CEUS were categorized as diffuse homogeneous enhancement (30 % - in the first group; such enhancement wasn't observed in the second group), rim-like hyper enhancement (70 % of the patients from the first group, 75 % of patients from the second group) and is enhancement, such as intact liver parenchyma (25 % of the patients from the second group). There were detected additional metastases in 4 (22,2 %) of patients 18 (100 %) in the delayed phase. There were significant differences in time of the beginning the vascular phases between patients from the first and second groups. The latest beginning of the wash-in stage was observed in liver metastases in patients from the second group (25,8 sec. from the injection of the contrast). The earliest beginning of the washout stage was observed in liver metastases in patients from the first group (42,4 sec. from the injection of contrast). CONCLUSION. CEUS improves visualization of CRLM, in comparison with the grayscale B-mode. It is also possible to apply this technique in the assessment of chemotherapy in patients with CRLM, as there was a difference between the moments of the beginning wash-in and wash-out stages.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>колоректальный рак</kwd><kwd>метастазы в печени</kwd><kwd>УЗИ с контрастным усилением</kwd><kwd>оценка эффективности химиотерапии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>colorectal cancer</kwd><kwd>liver metastases</kwd><kwd>contrast-enhanced ultrasound</kwd><kwd>response prediction to chemotherapy</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">Алиев, В.А.
