Все больные оперированы.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ: при морфологическом исследовании в 9 случаях выявлены аденомы, в 6 случаях –  аденокарциномы различной глубины инвазии. При анализе характера контрастирования опухолей были  получены статистически значимые различия времени наступления контрастирования, при этом  контрастное усиление аденокарцином наступало достоверно быстрее (p=0,036). Установлены обратные корреляционные связи пиковой интенсивности контрастирования гипоконтрастных зон в  аденокарциноме с индексами Т (rxy=-0,781; p=0,001) и N(rxy=-0,519; p=0,047) и прямая корреляционная связь со степенью дифференцировки опухоли (rxy =0,742; p=0,002). Также выявлена обратная связь времени начала контрастирования с индексом T(rxy=-0,552; p=0,033).</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ: ультразвуковое исследование с контрастным усилением представляет собой метод визуализации, позволяющий в режиме реального времени проводить качественную и количественную оценку перфузии опухолевой ткани. Метод не является стандартизованным, однако, может стать полезным  неинвазивным методом оценки кровоснабжения опухолей прямой кишки на предоперационном этапе, а также имеет потенциал в оценке факторов риска лимфогенного метастазирования.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>AIM</title><p>AIM: to evaluate the diagnostic capabilities of contrast-enhanced ultrasound for the diagnostics of epithelial rectal tumors.</p></sec><sec><title>PATIENTS AND METHODS</title><p>PATIENTS AND METHODS: the study included 15 patients, who underwent endorectal ultrasound and transvaginal contrast-enhanced ultrasound. All the patients underwent surgery.</p></sec><sec><title>RESULTS</title><p>RESULTS: morphology revealed adenomas in 9 cases, and adenocarcinomas with different invasion depth in 6 cases. When analyzing the tumors contrast, significant differences in arrival time of contrasting between adenomas and adenocarcinomas were obtained (p = 0.041), and the contrast enhancement of adenocarcinomas was faster (p = 0.036). Negative correlations of peak intensity of contrast enhancement of hypoenhanced zones in adenocarcinoma with indices T (rxy =-0.781; p = 0.001) and N (rxy = - 0.519; p = 0.047)and a positive correlation with the tumor differentiation degree (rxy=0.742; p = 0.002) were established. Also, the negative correlation of the arrival time with the index T (rxy=-0.552; p=0.033) was found.</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: contrast-enhanced ultrasound is an imaging technique that allows real-time qualitative and quantitative assessment of tumor tissue perfusion. The method is not standardized, but it can be a useful non-invasive method for assessing the blood supply of rectal tumors at the preoperative stage, and also has the potential to assess risk factors for lymphogenic metastasis. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ультразвуковое исследование с контрастным усилением</kwd><kwd>рак прямой кишки</kwd><kwd>аденома прямой кишки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>contrast-enhanced ultrasound</kwd><kwd>rectal cancer</kwd><kwd>rectal adenoma</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">Васильев А.Ю., Капустин В.В., Васильева Ю.Н., Шумина Я.А..
