螺旋CT仿真结肠内镜的临床应用研究

The Clinical Application of Helical CT Virtual Colonoscopy in Colorectal Diseases

目的 探讨螺旋CT仿真结肠内镜对结、直肠病变的检查方法及诊断价值。方法 采用螺旋CT机行 2 8例腹盆部扫描 ,并对图像行三维仿真结肠内镜重建。结果 正常 3例 ,直肠息肉 4例 ,结、直肠癌 11例 (2例为阻塞型 )。病理结果为正常 2例 ,直肠息肉 3例 ,结、直肠癌 13例 ,符合率 88.9%。结论 螺旋CT仿真结肠内镜是一种易操作的无创性检查方法 ,对结肠及直肠息肉、肿瘤等病变有很大诊断价值 ,可在术前提供重要信息。

Objective To study the methods and value of CT virtual colonoscopy in the diagnosis of colorectal diseases. Methods Twenty eight cases of abdomen and pelvis scanning were performed by helical CT scanner, and the 3D virtual colonoscopy were reconstructed. Results There were 3 normal colons, 4 rectal polyps, 11 colorectal carcinomas (including two obstructive colon carcinomas) on the CT virtual colonoscopy, while the pathology result were 2 normal colons, 3 rectal polyp and 13 colorectal carcinomas. The conformity was 88.9%. Conclusion CT virtual colonoscopy is an easily performed noninvasive method. It is valuable in the diagnosis of colorectal diseases such as polyp, carcinoma.
