目的探讨进展期胃癌在螺旋CT上的基本影像及诊断价值。方法收集36例经病理证实的胃癌螺旋CT扫描图像,复习文献资料,对胃癌在螺旋CT上的表现进行综合分析,探讨胃癌在螺旋CT影像学上的基本征象。结果进展期胃癌螺旋CT基本征象为胃壁增厚、软组织肿块、胃腔狭窄及腔内龛影,增强扫描可见胃壁病变区异常强化。结论螺旋CT作为胃癌的诊断方法之一,在对进展期胃癌做出诊断的同时可以发现胃癌的临近侵犯及远处转移。对临床治疗方法的选择有很大的帮助。
Objective To explore the basic imaging and diagnostic value of advanced gastric cancer on spiral CT. Methods Thirty-six cases of pathologically confirmed gastric CT images were reviewed retrospectively. The clinical manifestations of gastric carcinoma on spiral CT were analyzed comprehensively to explore the basic features of spiral CT imaging. Results The basic signs of spiral CT in advanced gastric cancer were gastric wall thickening, soft tissue mass, narrowing of gastric cavity and niche of cavity. Enhanced scanning showed abnormal enhancement of gastric wall area. Conclusion As one of the diagnostic methods of gastric cancer, spiral CT can detect the adjacent invasion and distant metastasis of gastric cancer while diagnosing advanced gastric cancer. The choice of clinical treatment methods is of great help.
