摘　　要：目的 探讨胃肿瘤的MSCT检查技术，提高胃癌的CT诊断率。方法16例胃肿瘤性患者进行MSCT检查及后处理重建，分析胃腔、胃壁及病灶的显示情况。结果14例病人胃腔充盈及扩张良好，胃壁、胃粘膜能够清晰显示；11例中晚期胃癌局部胃壁在扫描各期形态固定，而邻近正常胃壁形态多变；病灶表面及胃粘膜在门脉期呈线样明显强化，延迟期胃壁全层及病灶呈均匀或不均匀性强化。结论良好的胃腔准备及MSCT三期增强对胃肿瘤的评价有重要价值。object： To explore the examination technique with MSCT for stomach tumors and to improve the diagnostic accuracy for carcinoma of stomach.Methods and materials ： 16 cases of carcinoma of stomach received MSCT examination and post-reconstruction were processed to analyze the gastral cavity, gastric wall and the lesion itself. Result： 14 cases showed fine gastral cavity, and gastric wall and gastric mucous membrane were clearly seen; H cases were found fixed in all scanning phases, while adjacent GW varied in different phases, lesion and gastric mucous membrane were line-like enhanced. All layers of the stomach and the lesion showed uniform and ununiform enhancement.Conclusion： well preparation of the gastral cavity and three-phase scan protocol are of vital importance.
