1、影像学检查对结直肠癌诊断的评价作者：朱州，黄顺荣，秦千了，冯泽荣，麦威作者单位：广西壮族自治区人民医院胃肠外科，广西南宁530021【摘要】冃的探讨影像学检查在结直肠癌诊疗中的应用价值。方法冋顾性分析152例结直肠癌患者的B超、气顿双对比造影、结肠镜、螺旋CT扫描等四种检查资料，统计四种影像学检查的病灶发现率、肠癌诊断符合率、肿瘤部位检查符合率、淋巴结转移检出率。结果B超、气顿双对比造影、结肠镜、螺旋CT扫描对病灶的发现率分别为64.5%、92.6%x94.1%、88.9%,诊断符合率分别为50.6%、83.6%、89.6%、80.2%,B超
2、与另三种检查比较，病灶发现率、肠癌诊断符合率有显著性差异；肿瘤部位检查符合率四种检查无差异；B超和螺旋CT的淋巴结转移检出率有显著差异。结论B超适用于有实质性脏器转移的检查；气顿双对比造影能准确判断肿瘤部位；结肠镜是诊断结直肠癌最有效的方法；螺旋CT检查可显示肿瘤侵犯范围和转移情况，为临床确定手术方式。【关键词】结直肠癌；B超；气顿双对比造影；结肠镜；螺旋CTTheevaluationofimagingexaminationinthediagnosisofcolorectalcancerZHUZhou,HUANGShunrong,QINQia
