Цель исследования – оценка возможности визуализации РПЖ с помощью 320срезовой перфузионной компьютерной томографии (ПКТ). Были оценены результаты обследования 15 пациентов с подозрением на РПЖ. Исследования были выполнены на 320срезовом спиральном компьютерном томографе Aquilion One (Toshiba, Япония). Перфузию предстательной железы вычисляли методом максимального градиента. Далее на каждой перфузионной карте размещали зоны интереса. Для каждой из зон интереса рассчитывали следующие показатели: средняя скорость кровотока, нормализованная скорость кровотока, разница скорости кровотока в контрлатеральных зонах интереса, разница нормализованной скорости кровотока в контрлатеральных зонах интереса. Различия между показателями в зависимости от результатов гистологического исследования каждой из зон интереса оценивали дисперсионным анализом с последующим попарным сравнением с критерием Тьюки. Статистическую значимость различий оценивали в специализированном языке программирования R v3.2, с применением пакетов «pROC». Всего было получено 180 биоптатов. Из них 19 – РПЖ Σ Глисона 6, 17 – РПЖ Σ Глисона 7, 5 – РПЖ Σ Глисона 8, 7 – воспаление, 121 – отсутствие патологических изменений, 11– простатическая интраэпителиальная неоплезия. Площади под ROC-кривыми изучаемых показателей: средняя скорость кровотока – 0,6343, нормализованная скорость кровотока – 0,5300, разница скорости кровотока в контрлатеральных зонах интереса – 0,5875, разница нормализованной скорости кровотока в контрлатеральных зонах интереса – 0,6263. Результаты нашего исследования демонстрируют малую чувствительность метода в выявлении РПЖ низкой степени злокачественности.</p></abstract><trans-abstract xml:lang="en"><p>Visualization of prostate cancer remains an actual problem in urology and oncology. Purpose of the study – evaluation of prostate cancer visualization using 320-slice perfusion computed tomography (PCT). PCT results of 15 patients with suspected prostate cancer were evaluated. Studies were performed with the 320-slice spiral computed tomography Aquilion One (Toshiba, Japan). Perfusion of the prostate was calculated by the maximum gradient. Next, the areas of interest were placed on each perfusion map. For each of the areas of interest, the following indicators were calculated: the average blood flow velocity, normalized blood flow velocity, the difference of blood flow velocity in the contralateral areas of interest, the difference of the normalized blood flow velocity in the contralateral areas of interest. Differences between indexes depending on the results of histological examination for each area of interest were evaluated by the variance analysis and by pairwise comparison with the Tukey’s criterion. Statistical significance of differences was assessed by the specialized computer language R v 3.2, using pROC packets. Totally, 180 biopsies were obtained. 19 – prostate cancer Σ Gleason 6, 17 – prostate cancer Σ Gleason 7, 5 – prostate cancer Gleason Σ 8, 7 – inflammation, 121 – not pathological, 11 – prostatic intraepithelial neoplasia (PIN). The areas under the ROC curves for the studied parameters were: average blood flow velocity 0.6343, normalized blood flow velocity 0.5300, difference of blood flow velocity in contralateral areas of interest 0.5875, difference of normalized blood flow velocity in the contralateral areas of interest 0.6263. The results of our study shows low sensitivity of the method in detection of lowgrade prostate cancer.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак предстательной железы</kwd><kwd>перфузионная компьютерная томография</kwd><kwd>индекс Глисона</kwd><kwd>скорость кровотока.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>prostate cancer</kwd><kwd>perfusion computed tomography</kwd><kwd>Gleason score</kwd><kwd>blood flow velocity</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">Злокачественные новообразования в России в 2013 году (заболеваемость и смертность) / под ред.
