【摘要】：目的:探討單源雙能CT單能量圖像顯示直腸癌腹膜返折的價(jià)值。方法:回顧性分析105例行單源雙能CT掃描并經(jīng)手術(shù)病理證實(shí)的直腸癌患者資料,由兩位觀察者對(duì)混合能量圖像和40~140 keV每間隔10 keV而得到的11組單能量圖像中腹膜返折的顯示情況進(jìn)行主觀評(píng)分,對(duì)兩位觀察者各組評(píng)分結(jié)果的一致性進(jìn)行Kappa檢驗(yàn);采用Mann-Whitney U檢驗(yàn)將11組單能量圖像的主觀評(píng)分結(jié)果分別與混合能量圖像進(jìn)行比較;將混合能量圖像與單能量評(píng)分最高組圖像中直腸癌與腹膜返折位置關(guān)系與術(shù)中所見(jiàn)進(jìn)行對(duì)照,應(yīng)用卡方檢驗(yàn)比較兩組圖像對(duì)腫瘤位置判斷的符合率。結(jié)果:兩位觀察者對(duì)各組圖像質(zhì)量評(píng)分的一致性較好或一般。50~80 keV圖像質(zhì)量評(píng)分高于混合能量圖像,差異均有統(tǒng)計(jì)學(xué)意義(P0.05),其中60 keV圖像評(píng)分最高。混合能量圖像與60 keV圖像對(duì)直腸癌與腹膜返折位置關(guān)系的判斷符合率分別為80.95%、89.52%,差異具有統(tǒng)計(jì)學(xué)意義(P0.05)。結(jié)論 :單源雙能CT 50~80 keV圖像顯示腹膜返折的圖像質(zhì)量?jī)?yōu)于混合能量圖像,以60 keV圖像最佳,其對(duì)腹膜返折與直腸癌位置關(guān)系的判斷符合率高于混合能量圖像,具有一定臨床價(jià)值。
[Abstract]:Objective: to evaluate the value of single source and dual energy CT in displaying peritoneal reflux of rectal cancer. Methods: 105 cases of rectal cancer with single source and dual energy CT scan proved by surgery and pathology were analyzed retrospectively. The display of peritoneal reflux in 11 groups of single energy images was evaluated by two observers on mixed energy images and 40,140 keV images at intervals of 10 keV. Kappa test was performed on the consistency of the scores of the two observers. The subjective scores of 11 groups of single energy images were compared with mixed energy images by Mann-Whitney U test. The relationship between the location of rectal cancer and peritoneal reflexes in the highest single energy score group and mixed energy images was compared with the intraoperative findings. Chi-square test was used to compare the coincidence rate of tumor location between two groups of images. Results: the consistency of image quality score between the two groups was better or average .500.80. KeV image quality score was higher than mixed energy image. The difference was statistically significant (P 0.05). Among them, 60 keV images had the highest score. The coincidence rates of mixed energy images and 60 keV images in judging the position of rectal cancer and peritoneal refraction were 80.955% and 89.52%, respectively. The difference was statistically significant (P 0.05). Conclusion: the image quality of single source and dual energy CT 5080 keV images is superior to that of mixed energy images. 60 keV images were the best, and the coincidence rate of peritoneal reflux and rectal cancer location was higher than that of mixed energy images, which had certain clinical value.

【正文快照】： 不同位置的直腸癌在治療方案與預(yù)后判斷方面均存在差異[1],腹膜返折是判定直腸癌病灶位于腹膜腔內(nèi)外的重要標(biāo)記[2],可以對(duì)直腸癌的術(shù)前評(píng)估提供有效參考。CT現(xiàn)已逐步成為直腸癌術(shù)前的常規(guī)檢查,可以提供腫瘤浸潤(rùn)深度、范圍及有無(wú)轉(zhuǎn)移等重要信息。許多研究已經(jīng)證實(shí)單源雙能CT單
