Seventy patients with gastric cancer underwent
preoperative diffusion-weighted MRI and then surgical
resection. Mean and min ADC values of each gastric
cancer were obtained. Postoperative TNM staging of each
patient was determined. Mean and min ADC values of
gastric cancers with different TNM staging were
compared. Both mean and min ADC values of gastric
cancers correlated with postoperative T staging and N
staging. Both mean and min ADC values of gastric cancers
correlated with the area and depth of the lesions. The
preoperative ADC values of gastric cancers can provide
valuable information to predict postoperative TNM
staging of the patients.
