摘要 目的探讨晚期胃癌螺旋CT检查表现特征,为临床治疗提供依据。方法对42例确诊的晚期胃癌患者行水充盈后螺旋CT三期增强扫描。结果胃壁不规则增厚,呈肿块样突向胃腔,增强动脉期肿瘤即明显非均匀强化,胃壁分层不清;门脉期肿瘤持续强化,且比动脉期强化均匀,范围广泛;邻近侵犯表现为胃周脂肪线模糊消失,远处转移为在胰腺、肝脏、腹膜后、肺及纵隔骨骼等处发现转移病灶。结论晚期胃癌实施螺旋CT三期增强扫描是必要的,CT表现特征对临床合理拟定治疗方案具有指导价值。 Objective To explore the spiral CT demonstrating features of advanced gastric carcinoma, and evaluate their value on clinical therapy. Methods 3-period enhanced scans by the spiral CT were performed on 42 cases of patients with advanced gastric carcinoma, who underwent identified diagnosis. Results The irregular thickening gastric walls intruded upon gastric cavity, like as masses. On arterial period enhanced CT, the thick gastric walls showed nonuniform intensified, and their indefinite layers. On portal-vessel period enhanced CT, tumors were intensified more lastingly, uniform and abroad in range than on arterial period. Regional invading: fat borders were demonstrated indefinite or disappeared. Metastasis: metastasis loci were found in pancreas, liver, post-peritoneum, lung and mediastinum. Conclusion 3 - period enhanced CT for advanced gastric carcinoma possess the demonstrating features, which can effectively direct the establishment of clinical treating scheme.
