How is gastric ultrasonic examination to return a responsibility?
summary
The biggest advantage of gastric ultrasound is that the sound beam can penetrate the gastric wall, which can show the hierarchical structure of the gastric wall. As a non-invasive diagnostic method, it can provide the location, size and shape of gastric cancer, and sometimes estimate the extent of invasion of gastric wall. How is gastric ultrasonic examination to return a responsibility? Next, I'd like to share my views with you.

* the normal gastric sonogram of fasting stomach: the ultrasonogram of the stomach is different from that of its retention fluid, contraction state and section position. It can be represented as "crescent shaped", "saddle shaped" and oval. The central part of the stomach is a mixture of echoes of cavity gas, mucus and contents. When there is a large quantity of gas in the stomach, the rear area usually has accompanied by acoustic shadow. The low echo zone between the central echo and the surrounding echo is normal gastric wall echo.
Normal gastric sonogram after drinking water: after drinking water, the gastric cavity is filled with anechoic area, in which there are scattered strong echo points formed by tiny bubbles and mucus, which are easy to float. The normal gastric wall structure can be seen around the gastric cavity. The display of normal gastric wall structure is affected by the perpendicularity of the probe sound beam to the gastric wall, the filling degree of gastric cavity and the focusing degree of local sound beam. In contrast, the posterior wall of the gastric body in the antrum is easy to display, while the bottom and anterior wall of the stomach are difficult to display.
Normal gastric sonogram after administration of echo filling agent: when drinking the gastric filling agent, the ultrasound image clearly showed the passage and retention of the filling agent in the lower esophagus and cardia. The fundus, body and antrum of the stomach are clearly displayed, and the wall of the stomach can be clearly displayed. Under the high-resolution probe, there are three strong and two weak five layer echo structures. Starting from the intima, the first strong echo line and the second weak echo line indicate from the mucosal boundary and mucosal muscle layer.
matters needing attention
People with symptoms of this disease must be treated in time in the early stage. In addition, during the treatment period, we should ensure a good diet, never eat spicy food, and pay attention to supplement nutrients at any time.
