Abstract

　　Objective：To assess the diagnostic value of intestinal contrast medium，regular magnetic resonance imaging，diffusion weighted imaging （MRI－DWI） and True－FISP in Stomach cancer.

　　Method：50 patients with stomach cancer who take different contrast medium were analyzed in this study in regular MRI，True－FISP and DWI（different b，b＝600，b＝1000）imaging.

　　Results：Malignant pathological changes displayed super signal than benign ones on higher b（b＝1000）.compares the other means to be able to be clear about the pathological change real signal.

　　Conclusions：contract medium has better effect combine the diagnostic evaluation of DWI and True－FISP is higher in stomach cancer.

　　Key words：Stomach cancer ； Magnetic resonance diffusion imaging ； True－FISP－imaging
