Medical ultrasound scanners are non-invasive, radiation-free medical devices that can be used for diagnosis and treatment of a variety of diseases. In terms of gastric cancer screening, medical ultrasound scanners can provide a rapid, accurate and reproducible test method, which can contribute to the early detection and treatment of gastric cancer.

1. The status quo of gastric cancer

Stomach cancer is a common malignancy, with about 1 million new cases worldwide each year. China has one of the highest incidence rates of gastric cancer in the world, especially in Northeast China. The etiology of gastric cancer is complex, including environmental factors, genetic factors, dietary habits and many other factors. The early symptoms of gastric cancer are not obvious and it is difficult to be detected early, so how to effectively screen for gastric cancer has become an important topic.

2. Application of ultrasonic scanner in gastric cancer screening

Fast, non - invasive, no radiation

Screening for gastric cancer using a medical ultrasound scanner can provide a rapid, noninvasive, and radiation-free test. Patients only need to lie on the examination bed, without any incision or injection of a larger dose of contrast agent, which can reduce the pain and risk of patients.

Early detection of gastric cancer

Medical ultrasound scanners use high-frequency sound waves to create images that clearly show stomach tissue and blood flow. This is important for early detection of stomach cancer and can help doctors identify abnormalities such as stomach wall thickness, mucosal folds and lymph nodes. At the same time, medical ultrasound scanners can also assess the size, location and extent of tumors, which can help develop a rational treatment plan.

Improve diagnostic accuracy

The use of medical ultrasound scanner for gastric cancer screening can improve the diagnostic accuracy. Doctors can use ultrasound images to determine the shape, internal structure and blood flow characteristics of the tumor, and combine with other examination data for comprehensive analysis. This can avoid missed diagnosis and misdiagnosis and improve the accuracy and credibility of diagnosis.

Monitoring therapeutic effect

Medical ultrasound scanners can also be used to monitor the effects of treatment if stomach cancer has already been diagnosed. With regular ultrasounds, doctors can look at the size and shape of the tumor and determine whether treatment is effective or not and need to adjust the treatment plan.

Iii. Precautions for gastric cancer screening

When screening for stomach cancer, the following points need to be noted:

You should inform your doctor of your allergy history and medication use before the test to avoid allergic reactions or interference with the test results.

Gastroscopy is one of the most commonly used methods for gastric cancer screening, but it requires local anesthesia and laryngoscope insertion
