摘要
目的 对进展期胃癌行螺旋CT检查,探讨其CT表现及周围侵润情况和进行TNM分期的价值。方法 31例患者均在胃充盈状态下行螺旋CT扫描,其中19例口服3％的泛影葡胺溶液,12例口服水溶液,对CT征象进行分析和TNM分期。结果 全部病例在螺旋CT图像上均显示胃粘膜有改变,明确肿块发生部位,形态及胃周围情况。其中对12例行增强扫描,增厚的胃壁及肿块有强化,并能清晰显示>0.8cm的肿大淋巴结和有无肝脏转移。结论 螺旋CT对进展期胃癌显示率高,尤其TNM分期对指导胃癌的手术治疗具有重要意义。
Objective To study CT manifestations, the adjacent structures invasion and the value of TNM staging of advanced gastric carcinoma, with spiral CT(SCT) scanning. Methods 31 cases were examined by SCT scan after taking contrast medium orally, 19 cases took 3%meglumine diatrizoate, the other took water. Stomach was filled up, CT appearances were analyzed and TNM staging were diagnosed. Results Gastric mucosa changed in all cases on SCT films. Mass location, shape and gastric wall condition were clear. Enhanced SCT scanning undertook in 12 patients. Enhancement occurred in the thickened gastric wall and mass area. Lymph node larger than 0.8cm and with or without hepatic metastasis could be found obviously. Conclusions The manifestation rate of SCT to gastric carcinoma is high. SCT plays an important role in guiding surgical treatment especially after TNM staging.
