摘　　要：目的探讨磁共振成像对直肠癌术前T分期的判定价值。方法回溯性收集32个直肠癌病例,皆接受磁共振成像(MRI)检查和手术治疗,有详细的病理分析。以磁共振成像检查的影像来诊断直肠癌侵犯的层次,得到临床T分期的结论,再与手术后的检体报告来做相互印证,借此探讨磁共振成像影像在T分期诊断上的准确率。结果显示总体准确率为84.4%,总体高估率为9.4%,总体低估率为6.2%,Kappa值为0.76。结论利用MRI检查来做直肠癌分期的准确率较高,与病理结果有较好的一致性,可以提供直肠癌病患详细且正确的T分期讯息。Objective To explore the value of using MRI to judge T stage of rectal cancer .Methods The data of 32 cases of rectal cancer undergoing MRI and pathological examination and operative therapy were retrospectively collected and studied to judge the T stage of rectal cancer ,and the findings of MRI were compared with pathological reports to ensure the accuracy in diagnosis .Results The overall accuracy rate , the overall overestimate rate and the overall underestimate rate w ere 84 .4% ,9 .4% and 6 .2% respective‐ly ,and the Kappa value was 0 .76 .Conclusion MRI examinations can help to ensure accurate T stage for the diagnosis of rectal cancer .
