| 目的 评价高分辨磁共振成像(HR-MRI)对直肠癌术前TN分期的应用价值。方法 分析61例经手术病理证实的直肠癌患者的术前资料,由两名高年资影像医师协商阅片,并与最终手术病理结果对照。应用SPSS13.0软件对所得数据进行一致性检验。结果 HR-MRI用于直肠癌术前TN分期时,与病理T分期结果一致性好(Kappa=0.900,P<0.01)、与病理N分期结果的一致性较好(Kappa=0.716,P<0.01),HR-MRI对T分期的准确率为96.72%(59/61),N分期准确率为83.78%(51/61)。结论 HR-MRI可用于对直肠癌术前TN分期的评估。 |

| Objective To explore the value of high resolution MRI (HR-MRI) on pre-operative TN staging of rectal cancer. Methods The HR-MRI images of 61 patients with colorectal cancer confirmed by pathology were analyzed. The images were interpreted by two qualified doctors and the results were compared with final pathology. SPSS 13.0 was used for data consistency check. Results HR-MRI had high consistency with pathology in T staging of rectal cancer (Kappa=0.900, P<0.01), and moderate consistency in N staging of rectal cancer (Kappa=0.716, P<0.01), with accuracy rates of 96.72% (59/61) for T staging and 83.78% (51/61) for N staging. Conclusion HR-MRI can be used in pre-operative TN staging of rectal cancer. |
