Objective?To summarize and analyze the MRI imaging findings of advanced gastric cancer in order to improve the level of image diagnosis.?Methods?The plain and dynamic enhanced MRI findings in 8 volunteers and 30 patients with pathologically proven advanced gastric cancer were retrospectively analyzed.?Results?The stomach wall of advanced gastric cancer was inhomogeneous thickening with iso intensity or little hypo intensity signal on T1WI， and iso intensity or little hyper intensity signal on T2WI.?Cases with serosal infiltration，?the serous appearred indistinctly and rough.?In some cases，?the low signal zones between gastic wall and fat space were interrupted on T1WI out-of-phase image.?Cases with adjacent organs invaded，?the fat space was rough or disappeared.?The lesions showed obvious irregular or hierarchy enhancement on MRI dynamic contrast scanning.?Conclusions?Inhomogeneous thickening of gastic wall with abnormal signal intensity，?indistinctness or disappearance of fat space，?irregular or hierarchy enhancement are very valuable as diagnostic signs in patients suspective of advanced gastric cancer.
