摘要
目的:探讨多层螺旋CT(MSCT)增强扫描在结直肠癌患者术前分期中的诊断价值,并分析影响CT诊断的因素。方法:对51例电子肠镜检查并经术后病理证实为结直肠癌的患者,术前CT行扫描及多平面重组,根据图像资料进行临床分期,并与术中所见及术后病理结果对照比较。结果:CT术前诊断T分期与术后病理对照的Kappa值分别为T1期0.77,T2期0.61,T3期0.81,T4期0.92;N分期的Kappa值分别为N0期0.80,N1期0.67,N2期0.81。结论:MSCT平扫、增强扫描及多平面重组图像能够很好地显示直结肠癌的部位、大小、形态、累及范围及淋巴结的转移情况等,能够对肿瘤术前分期及制定合理的治疗方案提供依据。
Objective To evaluate the significance of multi - slice CT （MSCT） in the preoperative staging of colorectal carcinoma, and to analyze the factors of influence. Method 51 patients with colorectal carcinoma diagnosed by electrical Colonoscopy were studied by preopera- tive CT examination and muhiplanar reconstruction. Its images were used to investigate the staging of tumor, and the findings were compared with pathological results. Results In the diagnosis of thyroid nodlues, the consistency between MSCT in the preoperative T staging of colorectal carcinoma and pathological results were Kappa = （ T1 ,0. 77 ,T2 ,0. 61 ,T3 ,0. gl ,T4 ,0. 92） ,In preoperative N staging ere Kappa = （ No ,0. g0, N1 ,0. 67, N2 ,0. 81 ）. Conclusion The CT images with multi - planar reconstruction and enhanced scan can display shape, size, invasion and lymph node metastasis and so on, and it can provide the basis for preoperative tumor staging and establish reasonable treatment.
