目的探讨多层螺旋CT(MSCT)图像后处理技术在结肠肿瘤检查中的应用价值.方法 30例患者行结肠螺旋CT检查,工作站后处理(观察组).利用图形工作站的后处理功能作表面覆盖成像(SSD)技术重建三维CT结肠成像,经透明重建技术后获得与气钡双对比钡剂灌肠相似的透明图像；设定CT阈值和进行图像切割,使病变范围、细节充分显示.与30例钡剂灌肠及纤维结肠镜结果进行对照性研究(对照组).结果观察组30组获得的三维图像能较好地显示结肠的解剖关系及病灶的定位；所有患者的诊断符合率为100％,明显优于其它检查方法,其仿真内窥镜结果与纤维结肠镜结果吻合.结论运用多种三维成像方法能有效显示结肠肿瘤,可常规用于结肠肿瘤检查.

Objective To discuss the clinical value of application of three-dimensional reconstruction technique of MSCT in examination of colonic tumours.Methods Thirty patients underwent scanning using helical CT and post-processing on the workstation.All CTC images were reconstructed using shaded surface display (SSD) on workstation.Perspestive images such as the ones from DCBE were generated via raysum.The images could clearly demonstrate the extent and detail of the disorder by adjusting the CT value threshold.These results and that of barium enema and colon endoscopy were compared.Results Thirty cases had completely clinical and pathological data.3D images could correctly reveal the macroscopic morphology of colon tract and location of lesions.The correctly diagnostic rate was 100％ by MSCT,while the diagnostic rate by CTVE and colon endoscopy was basicly identical.Conclusion With the utilization of multiple methods,3D reconstruction can effectively demonstrate colonic tumours,and can be applied routinely in examination of colonic tumours.
