64排螺旋CT三期增强扫描在判断胃癌浸润深度的临床价值

目的:探讨64排螺旋CT三期增强扫描在术前判断胃癌浸润深度的临床价值。方法:确诊为胃癌的65例患者，术前均通过64排螺旋CT三期增强扫描判断胃癌浸润的深度，与术中探查及术后病理结果进行对比。结果:65例胃癌患者术前行64排螺旋CT三期增强扫描，通过与术中探查及术后病理对比，对胃癌T分期总的准确率为84.62%（55/65），T1期为83.33%（5/6），T2-3期为89.47%（34/38），T4a期为75%（12/16），T4b期为80%（4/5）。 结论:64排螺旋CT三期增强扫描在术前判断胃癌浸润深度的准确度高，为判断能否手术切除提供可靠的依据。

Clinical value of 64-slice spiral CT triple-phase enhanced scanning in T staging of gastric cancer

Objective: To study the clinical value of 64-slice spiral CT triple-phase enhanced scanning in the preoperative T staging of gastric cancer.Methods:Patients with gastric cancer were examined by preoperative 64-slice spiral CT triple-phase enhanced scanning,preoperative T staging was evaluated,which compared with intraoperative palpation and postoperative pathological results.Results:Compared with intraoperative palpation and postoperative pathological results，the accuracy rate of sixty five patients with gastric cancer preoperative T staging was 84.62% （55/65）,T1 staging was 83.33%（5/6）,T2-3staging was 89.47%（34/38），T4a staging was 75%（12/16），and T4b staging was 80%（4/5）by 64-slice spiral CT triple-phase enhanced scanning.Conclusion:The accuracy rate was high in T staging of gastric cancer by 64-slice spiral CT triple-phase enhanced scanning,which can provide valuable information in determining resectability of the tumor.
