【摘要】：目的探讨直肠癌高分辨MRI的征象与其病理T2、T3分期的关系。方法回顾性分析52例直肠癌患者的术前MRI征象(包括低信号环中断征、索条影、毛刺征及肠周结节征),结合病理结果比较各征象与直肠癌T2、T3分期的关系。结果直肠癌T2、T3分期低信号环中断征、毛刺征及肠周结节征差异有统计学意义(P均0.05),索条影差异无统计学意义(P=0.154);低信号环中断征和肠周结节征与直肠癌病理T分期呈低度相关(r=0.333、0.313,P=0019、0.022),毛刺征与直肠癌病理T分期呈中度相关(r=0.523,P0.001);多因素回归分析显示毛刺征及肠周结节征可独立预测T3期直肠癌。结论高分辨MRI对直肠癌术前T分期具有一定价值,其毛刺征及肠周结节征可以独立预测直肠癌T2、T3分期。
[Abstract]:Objective to investigate the relationship between high resolution MRI and T 2 T 3 staging of rectal cancer. Methods the preoperative MRI signs (including hypointense loop interruption sign, cable shadow, burr sign and peri-intestinal nodule sign) were retrospectively analyzed in 52 patients with rectal cancer. The relationship between these signs and T _ 2T _ 3 staging of rectal cancer was compared with pathological findings. Results low signal loop interruption sign was observed in T _ 2T _ 3 staging of rectal cancer. There were significant differences in burr sign and periintestinal nodule sign (P < 0.05), but there was no significant difference in stripe shadow (P < 0.05). Low signal loop discontinuity sign and pericardial nodule sign were significantly correlated with pathological T stage of rectal cancer (P < 0.05), and burr sign was correlated with pathological T of rectal cancer (P < 0.05). Multivariate regression analysis showed that burr sign and periintestinal nodule sign could independently predict T3 stage rectal cancer. Conclusion High resolution MRI has a certain value in preoperative T staging of rectal cancer. Its burr sign and periintestinal nodule sign can independently predict T 2 T 3 staging of rectal cancer.
