| 摘 要： | 目的探讨16层螺旋CT结肠成像在结肠病变的应用价值。方法应用16层螺旋CT对15例经手术病理证实的结肠癌、2例纤维结肠镜证实结肠息肉和1例结肠癌合并一枚息肉共18例患者进行CT容积扫描，在AW4．1工作站进行三维成像和仿真内窥镜、多平面重建观察，并与手术病理或纤维结肠镜结果相对比。结果18例CT结肠成像效果良好，诊断16例结肠癌病变范围、浸润情况及淋巴结转移情况与手术结果基本一致。结论16层螺旋CT结肠成像对结肠癌术前分期有很高临床参考价值。

| Abstract: | Objective To investigate the clinical value of 16-slice helical CT colonography in the diagnosis of colon tumor and polypus. Methods 16-slice helical CT volumetric scanning was performed in 18 patients with colonic disease, including colonic tumor （n=16） and colonic polypus （n=2）. 3D images, virtual endoscopy and multiplanar reformation were obtained in the AW4.1 workstation. CT appearances were compared with operation and fiberoptic colouoscopy. Results Satisfied results were achieved from 18 patients, no difference found in results between CT colonography and operation in 16 patients with colonic tumor. Conclusion 16-slice helical CT colonography is of great value in preoperative staging of colonic tumor and have a high value in clinical application. |
