摘　　要：目的通过与CT的对照研究,评价胃腔超声造影在胃癌定性及分期诊断中的价值。方法回顾性分析52例胃癌患者胃腔超声造影情况和CT检查结果。结果胃腔超声造影定性诊断符合率为90.38%,漏诊率为7.69%;CT诊断符合率为86.54%,漏诊率为11.54%;二者诊断符合率比较差异无统计学意义;胃腔超声造影T、N、M分期诊断符合率分别为73.68%、86.21%、100%,胃腔超声造影N、M分期诊断符合率高于CT(P<0.05),T分期诊断符合率与CT比较差异无统计学意义。结论胃腔超声造影对胃癌定性诊断符合率高,对N、M分期诊断符合率高,但对胃底部T分期诊断符合率较低,需结合其他诊断手段以提高诊断符合率。Objective To evaluate the value of contrast-enhanced ultrasound used in the diagnosis and staging of gastric cancer. Methods Fifty-two cases of gastric cancer were retrospectively analyzed. Images of CEUS, CT and the pathologic examination results were compared. Results The correct diagnostic rate, and the misdiagnostie rate of CEUS and CT were 90.38% vs. 86.54%,and 7.69% vs. 11.54%. There was no significant difference of accuracy of CEUS and CT. The rate of correct T, N, M staging using CEUS was 73.68%, 86.21%, 100% ,respectively. The rate of correct of N and M staging using CEUS was higher than using CT（P〈0.05）. Tile rate of correct T staging using CEUS is not significant compared with CT（P〈0.05）. Conclusion Except for the gastric fundus cancer lesions, CEUS is valuable in gastric cancer diagnosis, N and M staging.
