【摘要】 目的探讨16层螺旋CT仿真肠镜对结肠癌诊断及局部浸润范围的判断价值。方法73例手术证实的结肠癌患者,手术前1周分别进行电子结肠镜及16层螺旋CT检查,CT扫描后进行图像后处理对局部浸润范围进行判断,与术后病理分期进行对照。结果16层螺旋CT仿真肠镜对结肠癌总确诊率为90.4%,对肿瘤浸润深度总诊断准确率为83.3%。结论16层螺旋CT增强扫描结合肠道重建技术是诊断结肠癌的有效方法,并且能较好地进行局部浸润范围判断。更多还原

【Abstract】 Objectives To evaluate the value of diagnosis and local invasion of colon cancer by 16-slices spiral-CT. Methods Seventy-three cases of colon cancer proved by operation and pathology were examed by electronic colonoscope and 16-slices spiral-CT prior to operation respectively. Local invasion was assessed combing with the post-processing scans, compared with pathology. Results The accuracy of diagnosis and local invasion of colon cancer are 90.4% and 83.3%, respectively. Conclusions The enhancing scan of 16-slices spiral-CT combining with reconstruction technique is an effective method for diagnosis of colon cancer, and can judge the local invasion of colon cancer well.更多还原
