“No.1” to “No.16” are station numbers of regional lymph nodes of stomach, classified according to the Japanese classification of gastric carcinoma. “n” represents the sum of lymph nodes of each station visualized on CT. WE: Weak enhancement; OB: Obvious enhancement; RI: Ring enhancement; PA: Partial enhancement; met (-): No matastatic nodes; met (+): Metastatic nodes.
