| 目的探讨 256层螺旋 CT(MSCT)动态增强及多模式后处理技术在结肠癌术前诊断及分期中的应用价值。方法收集 2015年 12月至 2018年 12月，芜湖市第一人民医院 51例术后病理诊断及 TNM分期的结肠癌病人，采用 256层螺旋 CT(MSCT)对 51例结肠癌病人术前进行腹部 CT平扫、动态增强及多模式图像后处理检查，评估病变的部位、形态、范围、浸润程度、强化程度、邻近组织侵犯、引流淋巴结受累、远处转移情况，进行 CT术前诊断及 TNM分期，与术后病理诊断及 TNM分期的金标准进行对照。结果 256层螺旋 CT(MSCT)术前 T分期与术后病理 T分期比较， ≤T2期准确率为98.04%(50/51)T3期准确率为88.24%(45/51)，T4期准确率为 90.20%(46/51)，一致性好( K＝0.766，χ2＝65.623，P＜0.05)。术前 MSCT?N分术后病理 N分期与，期比较， N0准确率为 90.20%(46/51)N1期准确率为 76.47%(39/51)N2期准确率为 82.35%(42/51)一致性较好( K＝0.611， χ2＝40.937，P＜0.05)。结论 256层螺旋，CT(MSCT)动态增强及多模式，后处理技术对结肠癌病人的术前，诊断及分期具有重要价值，为临床选择合理的治疗方案及术前评估提供帮助。 |

| Objective To evaluate the value of dynamic enhancement and multi reconstruction mode with 256?slice spiral CT(MSCT)in the preoperative diagnosis and staging of colon cancer.Methods From December 2015 to December 2018，51 colorec? tal cancer patients with postoperative pathological diagnosis and TNM staging were collected from Wuhu First People’s Hospital and underwent abdominal CT plain scan，dynamic enhancement and multi?mode reconstruction before operation with 256?slice spi? ral CT(MSCT).The location，shape，extent，depth of invasion，degree of enhancement，adjacent tissues invasion，draining lymphnodes involvement and distant metastasis were carefully evaluated.Preoperative CT diagnosis and TNM staging were compared withpostoperative pathological results and golden standard of TNM staging.Results Compared with the postoperative pathological re? sults，T staging accuracy rates of preoperative MSCT were as follows:≤T2 stage was 98.04%(50/51)，T3 stage was 88.24%(45/ 51)，T4 stage was 90.20%(46/51)，with very good consistency(K＝0.766，χ2＝65.623，P＜0.05).N staging accuracy rates of preop? erative MSCT were as follows:N0 stage was 90.20%(46/51)，N1 stage was 76.47%(39/51)N2 stage was 82.35%(42/51)，with good consistency(K＝0.611，χ2＝40.937，P＜0.05).Conclusion Dynamicenhancementandm，ulti reconstruction mode with 256?slice spiral CT is of great value in the preoperative diagnosis and staging of colon cancer patients，which can provide valuable infor? mation for the selection of reasonable treatment and preoperative evaluation. |
