Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) has been applied in diagnosis of different cancers, however its potential in gastric cancer has not been fully explored. In this study, we research into the value of DCE-MRI parameters in evaluating the response to chemotherapy in gastric cancer. It was found that the Ktrans and Ve values showed good predictive performance through distinguishing responders from non-responders, which could provide effective technical assistance for the choice of clinical treatment.
