Gastric cancer is one of the most common malignant tumors in our country. At present, the main methods of clinical diagnosis of gastric cancer are barium contrast, gastroscope and biopsy. Many gastric cancers can obtain a definite diagnosis through the above methods. However, the above inspection methods are for mucosal surface observation, and the relationship between gastric lesions and the surrounding organs, there is no abdominal lymph node metastasis, the above methods are very limited.

Gastric cancer in CT mainly for the following signs:
