Gastric ultrasound

Gastric ultrasound is a non-traumatic diagnosis method in which the sound beam can penetrate the gastric wall and can show the hierarchical structure of the gastric wall. It can provide the clinical location, size, and shape of gastric cancer, and can sometimes estimate the extent of lesions invading the gastric wall. It can find early gastric cancer, understand the metastasis of gastric organs, make up for the lack of gastroscopy and X-ray examination, and provide a basis for clinical treatment options. At present, the detection rate of gastric cancer by abdominal ultrasound is low, and the sensitivity to early gastric cancer is only 15%, so it is not used as a screening method for gastric cancer.
