摘　　要：目的探讨多平面三维超声(3D-US)诊断胃癌及其术前分期的应用价值。方法对70例胃癌患者分别进行二维超声(2D-US)、3D-US及增强CT(CE-CT)检查,并与胃镜及手术病理检查结果进行对照分析。结果 2D-US、3D-US及CE-CT诊断胃癌的准确率分别为81.4%、94.2%、78.5%,三者之间比较差异有统计学意义(P<0.05)。2D-US、3D-US及CE-CT对胃癌分期诊断符合率分别为86.0%、90.9%、65.5%,三者比较差异有统计学意义(P<0.05)。3D-US分期准确率及术前T分期准确率明显高于2D-US及CE-CT。结论 3D-US诊断胃癌及术前分期准确率较高,可以作为胃癌诊断和术前T分期的重要补充检查方法。Objective To explore the value of multi-tomography three-dimensional ultrasonography in diagnosis and pre-operation staging of gastric carcinoma.Methods Two-dimensional ultrasonography（2D-US）,three-dimensional ultrasonography（3D-US） and contrast enhanced CT（CE-CT） were performed in 70 cases with gastric carcinomaes,respectively.The imaging results were compared with that of gastric endoscopy and pathology.Results The diagnostic accuracy for 2D-US、3D-US and CE-CT were 81.4%,94.2%,78.5%,respectively.The difference among three groups showed statistically significant（P〈0.05）.The accuracy of staging for 2D-US、3D-US and CE-CT were 86.0%,90.9%,65.5%,respectively.There was statistical difference among three groups.The diagnostic and staging accuracy for 3D-US was highest.Conclusion The diagnostic and staging accuracy of 3D-US for gastric carcinoma is high and it plays a complementary role in diagnosing and staging for gastric carcinomas,preoperatively.
