Infrared 3D examination has certain limitations for stomach diseases. Infrared three-dimensional examination can not clearly visualize the location and nature of gastric lesions, only as a means of initial screening. Currently, examinations for stomach diseases include breath test, gastroscopy, color ultrasound, abdominal CT, barium meal imaging, etc. If any of the above examinations are contraindicated, it is recommended that they be performed by a physician. If there are contraindications to any of the above tests, then the 3D ultrasound should be considered. The diagnosis of gastric diseases depends on the history, symptoms, signs and auxiliary examinations. If you have symptoms of stomach discomfort, it is recommended that you go to the hospital in time and be guided by your doctor to choose the appropriate examination program.
