目的：研究CT、MRI对直肠癌临床术前分期的诊断价值。方法以我院2013年1月-2015年1月经手术病理证实的80例直肠癌患者为研究对象，术前接受CT或MRI检查，各40例，以术后病理临床分期为金标准，比较CT、MRI对直肠癌术前临床T分期及淋巴结诊断准确率。结果与术后病理T分期结果比较，CT对T1-2期、T3期、T4期、总诊断准确率分别为57.1%、72.2%、66.7%、67.5%；,MRI对T1-2期、T3期、T4期、总诊断准确率分别为87.5%、84.2%、76.9%、82.5%。CT、MRI对淋巴结诊断总准确率分别为62.5%、80.0%。CT、MRI对术前T分期、淋巴结诊断总准确率比较差异均无统计学意义(P＞0.05)。结论 MRI对直肠癌术前T分期、淋巴结转移诊断准确率相比CT更高，但无明显差异。

Objective To study the diagnostic value of MRI and CT in the preoperative staging of rectal cancer.Methods 80 cases of patients with rectal cancer confirmed by operation and pathology during January 2013 to January 2015 were selected as the research objects. All the patients received CT or MRI examination before operation with 40 cases in each group. The postoperative pathological clinical staging was taken as the gold standard to compared the diagnostic accuracy of CT and MRI in preoperative clinical T staging of rectal cancer and lymph nodes.Results Compared with the results of postoperative pathological T staging, the accuracy rates of CT in the diagnosis of stage T1-2, stage T3, stage T4 and total diagnosis were 57.1%, 72.2%, 66.7% and 67.5%, respectively while those of MRI were 87.5%, 84.2%, 76.9% and 82.5%, respectively. The total accurate rates of CT and MRI in the diagnosis of lymph nodes were 62.5% and 80% respectively. There was no significant difference in the total accuracy rates of CT and MRI in the diagnosis of preoperative T staging and lymph nodes (P>0.05).Conclusion The accuracy rates of MRI in the diagnosis of preoperative T staging and lymph node metastasis are higher than those of CT, but there is no significant difference.
