With the continuous development of medical technology, medical ultrasound scanners have become one of the important tools for doctors to diagnose gastrointestinal diseases. This examination method is non-invasive, safe and reliable, and can obtain accurate results in a short period of time, making it widely used in clinical diagnosis and treatment. This article will introduce the principles, characteristics, and application scenarios of medical ultrasound scanners in the diagnosis of gastrointestinal diseases.

1、 The principle of medical ultrasound scanner

Medical ultrasound scanner is a device that utilizes the principle of sound wave transmission to detect the state of internal tissues and organs in the human body. Medical ultrasound scanners emit high-frequency sound waves to body parts, then receive the reflected sound signals, which are processed by computers and displayed in real-time on the screen. The working principle of medical ultrasound scanners is to display the internal structure of the human body based on the propagation speed and reflection intensity changes of sound waves in different tissues.

2、 Characteristics of medical ultrasound scanners

1. Non invasive

Ultrasound examination is a non-invasive method that does not require surgery or puncture, making it relatively safe and harmless for patients.

2. High accuracy

Medical ultrasound scanners can obtain detailed structural images of the gastrointestinal tract in a short period of time, with high resolution, high accuracy, and repeatability.

3. Multifunctional

Medical ultrasound scanners can achieve various detection modes, such as conventional B-ultrasound, blood flow measurement, three-dimensional imaging, etc., and can be applied to the diagnosis of different gastrointestinal diseases.

4. Easy to use

Medical ultrasound scanners are simple and convenient to operate, and can be completed in outpatient or examination rooms. Patients do not need to be hospitalized or observed to complete the examination.

5. No radiation

Medical ultrasound scanners are non radiation examination methods that do not generate electromagnetic radiation or radiation hazards, and do not have any impact on the human body.

3、 Application of medical ultrasound scanner in the diagnosis of gastrointestinal diseases

Diagnosis of gastric diseases

Medical ultrasound scanners are widely used in the screening and diagnosis of gastric cancer. It can detect changes in gastric wall thickness and mucosal morphology, as well as conditions such as gastric tumors, ulcers, and inflammation.

Diagnosis of intestinal diseases

The use of medical ultrasound scanners to diagnose intestinal diseases can detect the internal structure and function of the intestine, such as the size, shape, thickness of the intestinal wall, and tumors. In addition, it can also detect the condition of intrahepatic and extrahepatic bile ducts, the size, morphology, and pathological changes of the pancreas.

The diagnosis of functional gastrointestinal diseases using medical ultrasound scanners can examine functional gastrointestinal diseases such as esophageal reflux, gastrointestinal peristalsis, and gallbladder emptying. By evaluating the movement status of the gastrointestinal tract, it can be determined whether it is normal, and thus diagnose whether the patient has gastrointestinal motility disorders.

Diagnosis of liver and gallbladder system diseases

Medical ultrasound scanners can also be used for the diagnosis of liver and gallbladder system diseases, such as liver cysts, liver cancer, gallbladder stones, etc. It can evaluate the size, morphology, and blood flow of the liver and gallbladder, as well as detect the narrowing of the intrahepatic and extrahepatic bile ducts and the effectiveness of stone removal.
