摘　　要：本文报告应用水充盈低张胃CT动态扫描对胃癌病人进行术前疾病分期。以50例正常人测定数据为标准,结果发现75例胃癌病人均测得肿块。CT测得肿块的直径最小2cm,最大15cm,平均6.78±2.63cm。65例进行手术治疗的病人,术中发现淋巴结肿大45例,共取得121枚淋巴结,其中CT测得84枚。直径<0.6cm的淋巴结CT检出率为23.81%,而直径>1.0cm者CT检出率达到91.67%,其中病理诊断为癌转移者59枚。CT对邻近器官侵犯的检出率较高,各器官受累的判断准确率为97.33%。CT分期与病理分期的吻合率为85.33%。Fifty normal volunteers and 75 gastric cancer patients were examined with dynamic CT scan by water filling technique. Dependent on the normal volunteers data, the tumors were identified in all gastric patients with an average diameter of 6.78cm. 65 patients were operated. Total 121 enlarged lymph nodes were found in 45 patients. Among them, 84 lymph nodes were detected by CT scan. The detecting rate of lymph nodes was depended on their diameter. It is 23.81% in diameter of lymph nodes < 0.6cm group while it is 91.67% in diameter >1.0cm group. The accuracy of CT scan in detecting of around organs infiltration of tumor is 97.33%. The accuracy of disease staging is 85.33%.
