彩色多普勒超声在中老年结肠癌诊断中的应用(1)
[摘要] 目的 研究并总结彩色多普勒超声(CDFI)在中老年结肠癌患者诊断中的影像特点与应用中的优缺点。方法 选择近10年51例经彩色多普勒超声诊断的中老年结肠癌病例,研究、分析其影像与临床资料,将超声诊断与手术病理结果相对比。 结果 超声诊断与最终的手术及病理诊断一致者47例,符合率92.2%,CDFI对肝脏、肠系膜淋巴结转移、肿瘤直接浸润高度敏感。 结论 彩色多普勒超声结肠探查中根据特征性影像改变、肿块内部血流及动力学变化,能够正确诊断结肠癌,因其独特的优势,可作为中老年结肠癌的初始检查方法。[关键词] 彩色多普勒超声;结肠癌;诊断;应用价值
