作者对40例晚期胃癌术前用CT评价肿瘤的范围及其可手术性,并同手术与病理发现对照。该组贲门病变16例,贲门/胃底12例,体部7例,胃窦3例,全胃侵犯2例。13例肿瘤不能切除者(9例因侵犯周围组织,4例因广泛性转移)探查时作了大体病程描述。病人仰卧位,从膈肌至盆缘作8mm间距连续扫描,对无明显发现者用左、右卧位作4mm间距扫描,检查前30—60分钟口服胃影葡胺300～600ml或服特制的钡混悬液,开始检查前常服200—300ml,有者为显示血管结构需静脉速注造影剂。作者见到,按UICC术后组织病理学分类
The authors evaluated the range and operability of 40 cases of advanced gastric cancer by preoperative CT using CT, and were compared with surgical and pathological findings. The group had 16 cases of cardia lesions, 12 cases of cardia/gastric fundus, 7 cases of body, 3 cases of gastric antrum, and 2 cases of total stomach invasion. The general course description was performed in 13 cases of unresectable tumors (9 cases of invasion of surrounding tissues and 4 cases of extensive metastases). The patient supine position, from the diaphragm to the edge of the diaphragm for a continuous scan of 8mm, for those with no obvious findings, use a left and right position for a 4mm pitch scan, check for 30-60 minutes before oral administration of meglumine, 300 to 600ml or a special one. Suspensions, usually 200-300ml before starting the examination, there are intravenous injection of contrast agent to show the vascular structure. The authors saw the histopathological classification according to UICC postoperatively
