摘　　要：目的探讨16层螺旋CT对大肠癌的诊断价值。方法对68例大肠癌患者进行16层螺旋CT扫描及成像分析,并对螺旋CT下大肠癌的部位、形态、生长方式、病理类型以及对Duke分期的判断进行分析,并与电子肠镜及手术病理检查结果进行对照研究。结果 68例中,经螺旋CT诊断60例,CT扫描表现为不同程度的充盈缺损及肠腔狭窄,增强CT主要呈中度及明显强化。CT对大肠癌病理类型的诊断准确率与结肠镜检查相比无显著差异(P>0.05)。CT判断Duke A期准确率为60.0%,B期准确率为72.7%,C1为68.8%,C2为57.1%,D为100%。结论 16层螺旋CT能清除显示大肠癌的形态、生长方式,能判断病理类型及病理分期,对大肠癌的诊断和治疗具有重要的指导价值。Objective To explore the value of 16-layer spiral CT in the diagnosis of large intestine carcinoma. Methods Sixty eight patients with large intestine carcinoma received the 16-layer spiral CT scanning and imaging analysis. Also the location, shape, growth pattern, and pathological type of the carcinoma and Duke g staging were analyzed. Control study was made in the results between this method and electronic enteroseope and pathological examination. Results Among the 68 cases ,60 ones were diagnosed by spiral CT. The CT scanning manifestation was filling defects and narrow of enteric cavity in different degrees. Enhanced CT showed middle degree and obvious enhancement. There was no significant difference in the accuracy rate of diagnosis for the pathological types of large intestine carcinoma between the CT and colonoscopic examinations （ P 〉 0.05 ）. The accuracy rates of CT for the judgment of Duke g A, B, C1, C2, and D stages were 60.0% ,72.7% ,68.8 % ,57.1%, and 100%. Conclusion The 16-layer spiral CT can clearly show the shape and growth pattern of large intestine carcinoma and judge the pathological type and stage. It plays a great role in the diagnosis and treatment of large intestine carcinoma.
