目的 初步评价ＣＴ检查结肠病变的价值。材料和方法 ３８例病例，男性２５例，女性 １３例。年龄 １８～７１岁，多平面二维图像和三维图像都来源于结肠充气后电子束ＣＴ连续薄层扫描横断面图像。通过将ＣＴ数据输入工作站进行三维模拟内镜检查，三维图像采用表面遮盖显示法重建。结果 本组中发现９例肿瘤和１０个息肉，２个息肉团结肠扩张不充分漏诊，本组中有２例假阳性病例。结论 ＣＴ检查结肠在诊断结肠病变方面有较大潜力，可能成为一种较其它检查更为理想的筛选方法。
Objective To evaluate the value of CT in detecting colonic lesions. Materials and Methods 38 cases, 25 males and 13 females. Aged 18 to 71 years old, multi-planar two-dimensional images and three-dimensional images are derived from colon inflatable electron beam CT continuous thin-section scanning cross-sectional images. Three-dimensional simulated endoscopy was performed by inputting CT data into a workstation, and the three-dimensional image was reconstructed using a surface covered display method. Results In this group, 9 cases of tumors and 10 polyps were found. Two cases of polyposis colonic dilatation were not adequately missed. There were 2 false positive cases in this group. Conclusion CT examination of the colon in the diagnosis of colorectal lesions have greater potential, may become a screening method more ideal than other tests.
