目的：探讨64层 MSCT对进展期胃癌术前T分期的准确性。方法：搜集经术前胃镜及病理活检证实的100例胃癌患者的病例资料，对其进行常规平扫及三期动态增强扫描后进行术前T 分期，并与术后病理T 分期对照，分期的准确性采用Kappa一致性检验。结果：MSCT对T2、T3、T4期胃癌分期的敏感度为58．33％、88．24％、80．95％；特异度为97．22％、75．76％、93．65％；符合率为91．67％、82．14％、90．48％，T分期总的符合率为82．14％。结论：64层 MSCT在进展期胃癌术前T分期中具有较高的准确性，对于胃癌术前评估及预后具有重要的指导意义。

Objective:To study the accuracy of 64-slice spiral CT (MSCT)in the diagnosis of T-staging of advanced gastric cancer before surgery.Methods:Clinical materials of 100 patients with gastroscopy and biopsy proved gastric cancer were recruited.MSCT were performed with plain and triphasic dynamic contrast enhancement before surgery.T-staging was evaluated and correlated with that of pathology.Kappa consistency test was used to study the accuracy.Results:The sensi-tivity of MSCT for T-staging of T2、T3 and T4 was 58.33%、88.24% and 80.95%,respectively.The specificity for T2、T3 and T4 was 97.22%、75.76% and 93.65% ,respectively.The accuracy for T2、T3 and T4 was 91.67%、82.14% and 90.48%,respectively.The accuracy on T-staging as a whole was 82.14%.Conclusion:Relatively high accuracy in T staging of advanced gastric cancer before surgery could be obtained by 64-slice MSCT,and it can provide reliable information for surgery guidance and prognosis prediction.
