报告２９例经手术病理确诊的弥漫浸润型胃癌的Ｘ线与超声征象。典型Ｘ线表现为胃腔缩小、壁僵硬、粘膜破坏中断；超声特点为胃壁增厚、层次结构消失、与相邻组织间的境界回声消失及区域淋巴结肿大等。认为Ｘ线对显示病变部位、病变范围、胃腔狭窄程度、胃壁僵硬度、粘膜破坏、蠕动功能异常等精确，定性诊断符合率高；超声对观察肿瘤的浸润深度、周围侵犯及淋巴转移等情况很可靠，利于制定治疗方案，弥补了Ｘ线检查的不足。
The X-ray and ultrasonographic features of 29 cases of diffuse infiltrative gastric cancer confirmed by pathology were reported. The typical X-ray manifested as narrowing of the gastric cavity, stiffness of the wall, disruption of mucosal destruction, and ultrasonographic features such as thickening of the gastric wall, disappearance of the hierarchical structure, disappearance of realm echo with adjacent tissues, and enlargement of regional lymph nodes. The X-ray showed that the X-ray showed accurate lesion location, extent of lesions, degree of gastric cavity stenosis, stiffness of the stomach wall, mucosal damage, abnormal peristalsis, etc. Qualitative diagnostic rate was high; Ultrasound was used to observe the depth of tumor invasion, peripheral invasion and lymphatic metastasis Very reliable, conducive to the development of treatment programs to make up for the lack of X-ray examination.
