关于胃癌的CT诊断价值,国内外已有报道,现将我院1991年6月至1998年4月间,CT诊断经胃镜及手术病理证实的40例胃癌的表现总结如下。 1 材料与方法 1.1 临床资料 40例胃癌中,男26例,女14例,年龄28～80岁。CT检查前行胃镜检查36例,全部行钡餐检查,其中腺癌37例,粘液腺癌3例。 1.2 检查方法 患者于检查前日禁食禁水,检查前30分钟口服温水500～1000ml,20分钟后再饮温水500～1000ml,并肌注654-220mg,即刻上检查床,再饮温水500ml,取仰卧位,先行平扫,由膈顶向下扫描至胰腺,再静脉加压滴注60％泛影葡胺或安其格纳芬100ml。全部患者均采用GEMAX640型全身扫描机,层厚5～10mm,间隔5～10mm。
The diagnostic value of CT in gastric cancer has been reported at home and abroad. The performance of 40 cases of gastric cancer diagnosed by gastroscope and surgical pathology in CT from June 1991 to April 1998 is summarized as follows. 1 Materials and Methods 1.1 Clinical data 40 cases of gastric cancer, 26 males and 14 females, aged 28 to 80 years old.
