摘要
目的:探讨低张结肠充气多层螺旋CT(MSCT)三期增强扫描结肠癌术前分期与术后病理的相关性.方法:对手术证实的结肠癌患者32例行MSCT三期增强扫描,横轴位结合多平面重组(MPR)图像进行TNM分期,与术后病理对照.结果:MSCT对结肠癌术前T分期、术前N分期、远处转移及TNM分期的诊断准确率分别为90.63%(29/32),84.38%(27/32),100%(4/4),以及90.63%(29/32),均与手术病理一致(kappa:0.807,0.673,1,0.803;均P<0.01).结论:结肠癌MSCT表现与手术病理之间具有较强一致性,可作为治疗前评估分期首选检查方法.
AIM： To evaluate correlations for the staging of colorectal cancer between enhanced multislice spiral computed tomography （MSCT） pneurnocolon and surgical pathology.
METHODS： Thirty-two patients diagnosed with colorectal cancer from surgery were examined by a three-phase enhanced scan with MSCT. Cancer was staged by Tumor, Node, Metastases （TNM） by axial images and multi-planar reformation （MPR） images. MSCT findings were compared with post- operative pathologic staging.
RESULTS： The diagnostic accuracy of T-stage and N-stage before operation, metastasizing and the TNM-stage of MSCT in colorectal cancer was 90.63% （29/32）, 84.38% （27/32）, 100% （4/4） and 90.63% （29/32）, respectively. All correlated with surgical appearances and pathological findings （Kappa： 0.807, 0.673, 1.0 and 0.803, respectively, both P 〈 0.01）.
CONCLUSION： A very good correlation exist between manifestations on enhanced MSCT with MPR and operative pathology. MSCT may become the first choice diagnostic modality for pre-treatrnent staging evaluations of colorectal carcinomas.
