目的 探讨多排螺旋 CT结肠成像术（CTC）对结肠癌术前的临床应用价值。方法 对35例经纤维肠镜确诊结肠癌患 者进行CT扫描，所有患者均完成CTC检查并住院行手术治疗，将 CT 数据传至工作站后处理，获取CTC图像，将所 得CTC的检查结果与手术病理结果对照。结果 CTC检出全部35例结肠癌，敏感性100%。CTC对T分期的诊断符合率分 别为T1期50.0%、T2期83.3%、T3期88.2%、T4期100%，对N分期的诊断符合率分别为N0期60.8%、N1期57.9%、N2期 50%。结论 CTC作为一种无创性检查方法，可以准确判断疾病程度，对于合理制定治疗方案具有十分积极的意义， 具有较高的临床应用价值。

Objective To investigate the clinical value of multi-row spiral CT colon imaging (CTC) for preoperative colon cancer. Methods 35 cases of colon cancer patients diagnosed by fiber colonoscopy CT scan, all patients completed the CTC examination and surgical treatment in hospital, the CT data to workstation post-processing, CTC of image, the proceeds of CTC test results compared with surgical pathology results. Results All 35 cases of colon cancer were detected by CTC, and the sensitivity was 100%. The diagnostic compliance rate of CTC for T staging was 50.0% in T1, 83.3% in T2, 88.2% in T3, 100% in T4, and the diagnosis compliance rate of N stage was 60.8%, N1 period 57.9%, and N2 period 50% respectively. Conclusion CTC, as a noninvasive examination method, can accurately determine the degree of disease, and has a very positive significance for the rational formulation of the treatment plan, which has high clinical value.
