摘　　要：目的:评估螺旋CT平扫、增强扫描及图像后处理技术在大肠癌术前分期中的价值。方法:对临床诊断大肠癌患者进行X线钡剂造影、螺旋CT平扫、增强扫描和图像后处理(SSD、MPR、CTVE等),对其进行CT分期并与术后病理TNM分期进行对照,对其中有手术、纤维结肠镜活检病理资料完整的110例进行回顾性分析。结果:本组病例对大肠癌T分期的符合率为63.6%,其中T0-2分期符合率仅为28.6%(8/28),T3分期符合率为81%(56/69),T4分期为96%(26/27);N分期诊断符合率为12.7%;M分期的诊断符合率为98.2%。结论:螺旋CT平扫、增强扫描及图像后处理技术,能较好地诊断肠腔内病变、病变的浸润及转移情况,并可进行大肠癌术前分期,尤其对于远处转移M分期的诊断具有明显优势。但对于T分期和N分期的诊断,仍有待于进一步提高。Objective： To determine the value of spiral CT and post processing technology in staging colorectal carcinoma. Methods： One hundred and ten patients who had histologically proved as the rectum or coloncarcinoma were studied. All of them were examined by SCT, X-ray bariumenemea and done with image post process（including SSD, MPR and CTVE）. The preoperative staging of TNM were used based on the findings of SCT. The results of SCT were compared with pathology examination in all cases. Results： The accuracy of SCT was 63.6% in T stage and 12.7% in N stage, 98.2% in M stage. Conclusion：SCT and post process were good methods for staging the colorectal carcinoma. It allowed for accurate depiction and staging of colorectal carcinoma, . However, the value of SCT for T and M staging in colorectal carcinoma was limited.
