目的探讨结直肠癌术前多层螺旋CT(MSCT)检查的价值。方法回顾性分析22例结直肠癌MSCT结肠成像,观察原始横断面图像,应用CT仿真结肠镜(CTVE),多平面重建(MPR),表面阴影遮盖(SSD)和透明显示(Raysum)等图像后处理技术,进行综合判断,并与术后病理及临床随访结果对照。结果 MSCT对结直肠癌定位及定性符合率为100.0%;病理分型符合率为86.4%(19/22);对DukesA期诊断敏感性100.0%,特异性94.7%;DukesB期诊断敏感性100.0%,特异性92.3%;DukesC期诊断敏感性71.4%,特异性100.0%;DukesD期诊断敏感性及特异性均为100%。结论术前MSCT检查对结肠癌分期有较高的诊断价值。
Objective To investigate the value of preoperative multi-slice spiral CT (MSCT) in colorectal cancer. Methods A total of 22 colorectal cancer patients with MSCT were retrospectively analyzed. The original cross-sectional images were observed. CTCT, MPR, SSD and Raysum images were performed. Treatment techniques, to make a comprehensive judgment, and postoperative pathology and clinical follow-up results of the control. Results The coincidence rate of MSCT in colorectal cancer location and characterization was 100.0%. The coincidence rate of pathological type was 86.4% (19/22). The sensitivity and specificity of DukesB was 100.0% and 94.7%, respectively. The diagnostic sensitivity of DukesB was 100.0% , Specificity 92.3%; DukesC diagnosis of sensitivity 71.4%, specificity 100.0%; DukesD diagnosis of the sensitivity and specificity were 100%. Conclusion Preoperative MSCT examination of colon cancer has a higher diagnostic value.
