Even if ultrasound testing does not pose significant risks in medical examinations, it must be carried out under the guidance of a physician. Pregnant women must also understand the difference between advanced medical ultrasound and basic medical ultrasound. Each ultrasound technology requires special training to be used, so only professional medical personnel can apply it correctly and safely.

With the development of medical technology, ultrasound scanners have become an important tool for diagnosing abdominal diseases. It can not only quickly and accurately obtain images, but also diagnose different types of abdominal diseases. This article will introduce the commonly used scanning method for diagnosing abdominal diseases - ultrasound scanner, and explore the clinical application of this technology.

1、 Principles of Ultrasonic Scanners

Ultrasound is a mechanical wave whose frequency exceeds the range that human ears can hear (20 khz). In an ultrasonic scanner, high-frequency sound waves are transmitted to the human body through a probe and echoes are received from within the body, thereby generating images. By scanning from different angles, images in different directions can be generated on the screen to assist doctors in disease diagnosis.

2、 Application of Ultrasound Scanning in Abdominal Diseases

Ultrasound scanning is widely used in the early diagnosis of abdominal diseases, such as gastric cancer, liver cancer, and gallstones.

1. Liver diseases

Ultrasound scanners can be used to observe and measure the liver. If there are abnormalities such as cysts, masses, and diseased tissues inside the liver, targeted puncture biopsy can be performed.

2. Gallbladder and bile duct diseases

In ultrasound scanning, the condition of stones, inflammation, and masses in the gallbladder and bile ducts can be clearly observed, and puncture treatment and treatment can be performed on this part.

3. Gastric cancer

Through ultrasonic scanning of the left epigastrium and epigastrium, the condition of the stomach wall can be grasped, the size and shape of the stomach can be observed, and the location, size and invasion of the tumor can be accurately judged by observing the internal tubes of the gastrointestinal tract.

4. Intestinal diseases

In the ultrasonic scanning, the masses, stenosis, inflammation and other pathological changes in the small intestine, ileum, colon, rectum, sigmoid colon and other parts of the digestive tract can be clearly observed. During the examination process of abdominal ultrasound scanner, comprehensive and dynamic observation of the internal structure of the digestive tract can be carried out by changing the angles of each scanning direction, and the examination results are accurate and reliable.

3、 The advantages of ultrasonic scanning

Ultrasonic scanners have many advantages, the most important of which is their non-invasive nature. This means that during testing, there is no need to inject any chemical reagents or radioactive substances internally, avoiding chemical or radiation damage, and it has high safety. In addition, ultrasound scanning does not produce any pain or unpleasant sensation, and is suitable for different age groups, especially pregnant and pediatric patients.
