目的：探讨3.0T MRI 与64层螺旋 CT 在进展期胃癌术前 T 分期中的诊断价值。方法对经胃镜病理证实的胃癌患者40例,于术前1周行 MSCT 及 MRI 检查,根据影像学资料进行 T 分期,并与术后病理结果进行对照。结果MRI 与 MSCT 术前 T分期与术后分期均有较好的一致性(Kappa-test ,P <0.05),MRI 与 MSCT T 分期的准确率分别为77.5%、72.5%,经统计学分析2种检查方法之间无统计学差异(McNemar-test ,P >0.05)。结论MRI 与 MSCT 在进展期胃癌术前 T 分期中诊断价值相当,MRI的诊断准确性稍高于 MSCT,尤其是在区分 T3、T4期具有潜在的优势。

Objective To explore the differential diagnosis value in preoperative T-staging of advanced gastric cancer with 3.0T MRI and 64-slice spiral CT.Methods 40 patients with advanced gastric cancer confirmed by gastroscopy and biopsy were admin-strated MRI and MSCT examination one week before surgery.Then the T-staging were evaluated by MRI and pathology.Results There was a good consistency of T-staging between MRI and MSCT compared with biopsy (Kappa-test ,P <0.05).The accuracy of T-staging by MRI and MSCT was 77.5% and 72.5%,respectively.There was no statistical difference in these two methods (Mc-Nemar-test ,P >0.05).Conclusion MRI is comparable to MSCT in the T-staging of the advanced gastric cancer,and the accuracy of MRI is seperior to MSCT,especially in T3 and T4 stage.
