Uneven increase in the signal of the stomach wall on DWI may be due to gastric ulcer, gastric polyp, gastric cancer, scarring in the stomach, and so on.
1. Gastric ulcer: after gastric ulcer, the tissue in the stomach will be thickened to resist the erosion of gastric acid, which will result in unevenly increased signal of the stomach wall on DWI.
2. Gastric polyp: after polyp grows in the stomach, the signal of the stomach wall will be unevenly increased on DWI.
3. Gastric cancer: Gastric cancer is the proliferation of abnormal tissues in the stomach wall, resulting in unevenly increased signal of the stomach wall on DWI.
4. Gastric scarring: In patients with a history of gastric surgery, the scar tissue of the surgical incision proliferates, resulting in unevenly increased signal of the gastric wall on DWI.
There are many other reasons for the uneven increase of the signal of the stomach wall on DWI, patients should consult a doctor in time, complete the relevant examinations to clarify the cause of the disease, and under the regular guidance of the doctor’s treatment.
