| 摘 要： | 目的:探讨双层螺旋CT仿真内镜成像在结肠肿瘤性疾病的术前评价中的价值。方法:30例高度怀疑结肠肿瘤性疾病的患者行双层螺旋CT扫描后,采用仿真内镜软件生成结肠仿真内镜图像,同时结合MPR、SSD、MIP和透明技术,观察结肠肿瘤的形态、位置、对肠管浸润的范围及长度、肠管周围及远处脏器的情况,并与电子结肠镜及手术病理结果对比。结果:30例中仿真结肠镜对肿块型结肠肿瘤的判断较电子结肠镜准确,两种方法的分型符合率分别为100%、89.4%;电子结肠镜对浸润型及溃疡型结肠肿瘤的判断较仿真结肠镜准确,其分型符合率分别为83.4%、100%;仿真结肠镜对病变肠管浸润的范围及长度的判定均高于电子结肠镜。结论:双层螺旋CT仿真内镜成像在结肠肿瘤术前诊断中有较大的价值,是电子结肠镜的重要补充检查技术。

| Abstract: | Objective:To evaluate the clinical value of two-slice CT virtual endoscopy in preoperative diagnosis of colon tumer.Methods:The volume scan of two-slice CT was performed in whole colon of 30 cases who were suspected of colon tumor,then data was transmitted to the work station and to obtain virtual endoscopy(VE) image using software.To the form,the situation and the depth of invasion were examed by using of MPR,3D surface shaded display(SSD) and raysum.The results of VE were correlated with those of electron... |
