摘　　要：目的探讨CT仿真结肠镜（cTvc）及其图像后处理技术对结直肠疾病的诊断价值。方法回顾性分析84例临床怀疑结直肠疾病患者的CTVC图像，同时结合多平面重建（MPR）、表面遮盖显示（SSD）和透明法重建图像，分析病变大小、形态及部位，将影像结果与电子结肠镜和病理进行对照。结果84例中有59例诊断为大肠癌（其中乙状结肠23例、直肠22例、升结肠11例、盲肠3例），直肠息肉8例，结肠多发性憩室3例，痔疮1例，正常13例。全部经手术病理或临床证实，诊断正确。结论CTVC有利于观察结直肠疾病的形态及特征，对大肠癌的临床分期和手术方案的选择具有重要意义。Objective To estimate the value of CT virtual colonoscopy （CTVC） and its image post- processing techniques in the diagnosis of colorectal diseases. Methods CTVC images of 84 patients with suspected colorectal diseases were retrospectively analyzed combined with multiple planar reconstruction （MPR）, shaded surface display （SSD） and transparent image reconstruction. The location, size, shape and type of the lesions were analyzed and the images were compared with electronic colonoscopy and pathologicspecimen finding. Results Fifty-nine of 84 patients were diagnosed as colorectal cancer （23 cases with cancer in sigmoid colon,22 cases in rectum, 11 cases in ascending colon and 3 cases in appendix）, 8 cases were porctopolypus, 3 cases were multiple colonic diverticula, 1 case was hemorrhoids, 13 cases were normal. All the diagnosis was confirmed correct by operation pathology or clinic. Conclusion CTVC can show the shape and other features of colorectal diseases, and has important significance for clinical staging and surgical planning of colorectal cancer.
