【摘要】 目的 对比研究多排螺旋CT仿真内镜及电子结肠镜对大肠肿瘤病变的显示能力和诊断价值。方法 65例大肠肿瘤疾病患者术前均行多排螺旋CT检查,扫描前10 min肌注山莨菪碱10 mg,自肛门注入适量气体。对扫描图像行仿真内镜重建,从检查方法、检查结果及对病变的显示能力等方面与电子结肠镜进行对比分析。结果 65例大肠肿瘤患者电子结肠镜全部检出,检出率为100%,CT仿真内镜正确检出62例,检出率为95.3%。直肠病变的定位诊断,仿真内镜及结肠镜的准确率分别为97.6%、88.3%,结肠病变的定位诊断,仿真内镜及结肠镜的准确率分别为90.9%、59%。结论 CT仿真内镜与电子结肠镜二者结合,可为临床治疗方案的选择提供更全面、精确的信息。更多还原

【Abstract】 Objective To evaluate the diagnostic value of CT virtual endoscopy(CTVE) and electronic colonoscope comparatively for colorectal carcinoma.Methods 65 patients with colorectal carcinoma were scanned on multislice helical CT before operation.Intra-muscular injection of 10 mg’s hypotonic agent was given 10 minutes before scanning,and administration of suitable gas inside the colon from anus was done.CT images were processed with virtual endoscopy(VE).Comparative analysis was performed between CTVE and colonoscopy in detection of colorectal lesions.Results 65 cases with colorectal carcinomas were discovered through electronic colonoscope,the detectable rate was 100%,and 62 patients were discovered through CTVE,the detectable rate was 95.3%.In localized diagnosis,the accurate rates were 97.6% and 88.3% for rectal carcinoma,90.9% and 59% for colonic carcinoma with CTVE and colonscopy,respectively.Conclusion CTVE in combination with colonoscopy can provide more imformations for clinic administration in colorectal carcinoma.更多还原
