Gastric cancer screening

Gastric cancer screening

Method: Gastric X-ray examination(Conducted in conform to the method of the Japanese Society for Gastrointestinal Cancer Examination)

Gastric X-ray examination is an examination of the inside of the stomach and its mucous membranes by x-ray.
First, the stomach is inflated by drinking 5 grams of a foaming agent to stretch the folds of the stomach and make it easier to see the surface.
Next, 150 cc of barium is taken, and the patient is rotated on the radiographic stand to form a coating of barium on the surface of the stomach for radiography.
About 8 images of the stomach are taken from various directions.
