摘　　要：目的术前MRI诊断直肠癌分期与术后病理检查结果的比较分析。方法选择2017年3月到2018年3月到医院就诊直肠癌患者80例,所有患者均进行MRI检查。以手术病理学检查为金标准,统计MRI进行术前T、N、M分期准确率。结果与金标准比较,MRI检测对T1-T4分期诊断准确性分别为95.00%,86.25%,91.25%,100.00%,T分期总准确率为86.25%;与金标准比较,MRI检测对N0-N2分期诊断准确性分别为87.50%,82.50%,90.00%,N分期总准确率为82.50%;与金标准比较,MRI检测对M0-M1分期诊断准确性分别为95.00%,80.00%,M分期总准确率为91.25%,灵敏度95.00%,特异度80.00%。结论MRI对直肠癌术前分期评估与术后病理结果符合率较高。Objective To compare and analyze the preoperative MRI diagnosis of rectal cancer staging and postoperative pathological examination results.Methods 80 cases of patients with rectal cancer in the hospital from March 2017 to March 2018 were selected.All patients were given MRI.Surgical pathology was used as the gold standard,and the accuracy rates of preoperative T staging,N staging and M staging were calculated by MRI.Results Compared with the gold standard,the accuracy rates of MRI for T1-T4 staging were 95.00%,86.25%,91.25% and 100.00%,and the total accuracy rate of T staging was 86.25%.Compared with the gold standard,the accuracy rates of MRI for N0-N2 staging were 87.50%,82.50% and 90.00%,and the total accuracy rate of N staging was 82.50%.Compared with the gold standard,the accuracy rate of MRI for M0-M1 staging were 95.00% and 80.00%respectively,and the total accuracy rate of M staging was 91.25%,and the sensitivity and specificity were 95.00% and 80.00%.Conclusion MRI has a high coincidence rate between MRI of preoperative staging evaluation and postoperative pathological results of rectal cancer.
