摘要
目的:比较经直肠超声造影(CEUS)和彩色多普勒超声(CDU)用于直肠癌与直肠间质瘤鉴别诊断的价值。方法:随机抽取2019年9月至2020年9月于我院接受手术治疗且术前行CEUS和CDU检查的直肠癌或直肠间质瘤患者各40例,比较直肠癌与直肠间质瘤患者CEUS、CDU检查参数的差异,以及两种检查方法对直肠癌和直肠间质瘤的诊断准确率。结果:1)CDU检查参数:直肠癌组患者病灶包绕肠腔率、病灶内部回声均匀率、阻力指数、血流峰值流速均显著高于直肠间质瘤组,P<0.05。2)CEUS检查参数:直肠癌组患者峰值强度(Imax)明显高于直肠间质瘤组,而上升时间(RT)、达峰时间(TTP)、平均渡越时间(mTT)明显低于直肠间质瘤组,P<0.05。3)诊断准确率:CEUS诊断直肠癌及直肠间质瘤的准确率(96.25%)明显高于CDU(81.25%),P<0.05。结论:CEUS和CDU用于鉴别诊断直肠癌与直肠间质瘤均具有一定价值,但两种检查方式相比,CEUS效果更好。
Objective To compare the value of contrast-enhanced ultrasound(CEUS)and color Dopple ultrasound(CDU)in differentially diagnosing rectal cancer from rectal stromal. Methods Randomly enrolled rectal cancer patients(40cases)and rectal stromal patients(40cases)who all received surgery(2019-09-2020-09)in author’s hospital,and preoperative CEUS and CDU inspection;then,compared both group’patients’ difference between CEUS parameter and CDU one,as well as diagnostic accuracy rate of both inspections on rectal cancer and rectal stromal. Results 1)CDU parameters inspected:in the rate of bowel cavity encysted,echophony smooth rate,resistance index,and flow peak velocity the patients with rectal cancer were all significantly higher than the patients with rectal stromal(P<0.05);2)CEUS parameters inspected:in Imax.the patients with rectal cancer were significantly higher than the patients with rectal stromal(P<0.05),and its RT,TTP,and mTT lower than the latter(P<0.05);3)Accuracy rate:the accuracy rate of CEUS in diagnosing both diseases was significantly higher than CDU’s one(96.25% vs81.25%,P<0.05). Conclusion In differentially diagnosing both diseases both inspections have certain value,only CEUS is better than CDU.
