摘　　要：目的:评价在直肠癌术前诊断及分期中应用多排螺旋CT(MDCT)与磁共振成像(MRI)的价值。方法:根据研究要求随机入选60例病例,所有患者经手术病理证实为直肠癌。根据术前影像学检查方法分为两组,每组各30例。比较病理结果与术前影像学诊断结果,获取两组患者各自影像诊断准确率,并将其进行对比。结果:两组患者诊断准确率比较结果显示,无论在T分期还是在N分期中MRI组都占有优势,其中T分期中差异有统计学意义(P<0.05),N分期中差异无统计学意义(P>0.05)。结论:MDCT或MRI皆可应用于直肠癌诊断与分期,MRI可作为首选的影像检查手段。Objective To evaluate the value of multi-detector CT(MDCT) and magnetic resonance imaging (MRI) in preoperative diagnosis and staging of rectal cancer. Method 60 cases were randomly selected according to the research requirement, and all the patients were confirmed as rectal carcinoma by surgical pathology.According to the preoperative imageological examination, two groups were divided with 30 cases of each group.To compare pathological results and preoperative imaging diagnosis, obtain the diagnostic accuracy of two groups of patients and then make comparison. Results The comparative results of accuracy rate of diagnosis from the two groups showed that the MRI group predominates in both T and N staging, and there was significant difference in the T staging ( P <0.05) while there was no significant difference in the N staging( P >0.05). Conclusion MDCT or MRI can be applied in diagnosis and staging of rectal carcinoma, and MRI can be used as a preferred means for imaging examination.
