摘　　要：为了评估磁共振成像(MRI)对直肠癌定位的准确性及确定肿瘤位置与肺转移率的相关性,146名直肠腺癌患者接受了腹部MRI、胸腹部CT及发病2周内的纤维内窥镜检查,在内窥镜下测量肿瘤距肛门边缘的距离,再与MRI显示的位置进行对比,分析二者的相关性;用运用多元回归方法对影响肺转移的重要因素进行统计学分析。结果表明,MRI显示的肿瘤位置与内窥镜检查的实际位置相近,相关性比较有统计学意义;另外,低位直肠癌肺转移的发生率明显高于高位直肠,差异有显著性。因此得出结论:直肠MRI检查可以准确显示肿瘤的位置,对预测肺转移率有一定的价值。In order to evaluate the accuracy of MRI in positioning rectal cancer and determining the correlation between the tumor location and pulmonary metastasis rate,146 rectal adenocarcinoma patients were examined with abdominal MRI,chest CT as well as fiber endoscopy within 2 weeks of the onset. Besides,the distance from the tumor to the edge of the anus was measured,which was compared with the position of the tumor determined on MRI display. Additionally,the important factors influencing the pulmonary metastasis were statistically analyzed using the multiple regression method. The results showed that the tumor location determined by MRI was near the actual position checked by endoscopy. The incidence of pulmonary metastasis in low rectal cancer was obviously higher than that of high rectal cancer. It is accordingly concluded that rectal MRI examination can accurately position the tumor and it has certain value in predicting the rate of pulmonary metastasis.
