摘要 目的:评价多层螺旋CT仿真内镜(CTVE)对大肠癌的临床应用价值。方法:对192例大肠癌患者经肛管注入气体1000~1500ml后行全腹快速容积扫描,横轴位数据传送至同机Volume Wizard工作站行CTVE成像,结果与电子肠镜及手术病理结果对照。结果:手术病理证实大肠癌192例,CTVE检出182例,检出率94.8%,分型符合率为94.8%。肠镜检出171例,检出率89.1%,分型符合率为89.1%。CTVE对右半结肠癌的定位符合率高于肠镜,CTVE对肿块型和混合型的判断符合率高于肠镜。结论:CTVE成像技术安全、方便、快捷、无痛苦、患者易接受,可以从任意角度及远、近两端分别观察肿瘤的形态特征,定位准确,并可判断肿瘤浸润范围,具有较高的临床应用价值。
