目的探讨CT仿真内镜(CTVE)及其后处理技术对结直肠癌评价中的应用价值。方法对40例临床怀疑结直肠癌患者行多层螺旋CT仿真内镜(CTVE)检查，并对图像进行后处理，应用多平面重建(MPR)、表面遮盖显示(SSD)和透明显示(Ray sum)等技术，将结果与肠镜和病理结果进行对照分析。结果40例中乙状结肠12例、直肠10例、升结肠4例、降结肠2例，正常12例，并均经手术病理或临床证实。结论 CTVE有利于观察结直肠癌的病变范围及形态等特征，对结直肠癌的临床分期及治疗方案的选择提供重要依据。

Objective To evaluate the value of CT virtual endo-scope (CTVE) and its image post-processing techniques in the diagnosis of colorectal cancer. Methods 40 cases of suspected colorectal cancer patients scan by MSCT virtual endo-scope, using multiple planar reconstruction (MPR), shaded surface display (SSD) and transparent image reconstruction(Ray sum).The results were compared with colonoscopy and pathologic specimen finding. Results 12 cases with cancer in sigmoid colon,10 cases in rectum,4 cases in ascending colon and 2 cases in descending colon of 40 cases, and 12 cases were normal. All the diagnosis was confirmed by operation pathology or clinic. Conclusion CTVE can show the features of colorectal cancer, and has important significance for clinical staging and surgical planning of colorectal cancer.
