Materials and Methods 80 cases with EGJ cancers were selected and divided into 2 groups randomly. All patients underwent CT scan after taking 800ml positive contrast media (n=40) or 800ml water (n=40). T staging diagnosis of all lesions was made on CT images. Comparison the accuracy of two contrast medias in EGJ cancer on CT images was performed, with postoperative pathology serving as the reference standard. Results In the positive contrast media group, T staging diagnosis was accurately made in 31 cases on CT images, the accuracy was 77.5%. In the negative contrast media group, T staging diagnosis was accurately made in 33 cases on CT images, the accuracy was 82.5%. The difference between two groups had statistical significance (plt;0.05). Conclusions The accuracy of water is higher than that of positive contrast media. Water is superior to positive contrast media in preoperative CT diagnosis of EGJ cancer. 【Keywords】 esophagogastric junction cancer contrast media tomography X-ray computed 在食管胃结合部（EGJ）癌CT检查中，口服对比剂对于小癌灶的检出，病灶大小及侵犯范围的确定，癌灶与周围组织关系的判断十分重要。当前，CT检查对比剂通常有气体对比剂、脂肪乳类
