Childhood liver disease has always been a focus of attention for pediatricians and parents. The liver is one of the most important organs in the human body, and its abnormal function often leads to many diseases. Medical ultrasound scanners play an important role in the diagnosis of liver diseases in children. This article will focus on the application and advantages of medical ultrasound scanners in the diagnosis of liver diseases in children.

The principle and characteristics of medical ultrasound scanners

Medical ultrasonic scanner is a non-invasive, convenient and safe Medical imaging device. Its working principle is to send high-frequency sound waves and then receive their reflected echoes in human tissues. By processing the echo signal, an image of the liver's interior is generated. Compared with traditional X-ray radiation, ultrasound has the advantages of low radiation and no side effects.

Application of medical ultrasound scanner in the diagnosis of liver diseases in children

1. Evaluation of liver size and morphology: Ultrasound scanning can accurately measure the size and morphology of the liver, helping doctors determine whether there is swelling or deformation. This is very important for the early diagnosis of liver diseases in children.

2. Intrahepatic blood flow assessment: Through ultrasound scanning, doctors can understand the blood supply situation of the liver, including the blood flow velocity, direction, and resistance of the hepatic artery and portal vein. This plays a crucial role in the diagnosis and treatment of diseases such as hepatitis and cirrhosis in children.

3. Evaluation of liver tissue structure: Ultrasound scanning can display the internal structural features of the liver, such as blood vessels, bile ducts, tumors, etc. Doctors can preliminarily determine the nature and location of the tumor based on the image display, thus providing reference for the next treatment plan.

4. Guide liver biopsy: For the diagnosis of liver diseases, biopsy is an important method. Ultrasound scanning can provide doctors with accurate location and size of the liver, thereby improving the success rate and safety during the biopsy process.

5. Disease tracking and efficacy evaluation: Liver diseases in children often require long-term treatment and observation. Ultrasound scanning can periodically evaluate changes in the liver, monitor treatment efficacy, and adjust treatment plans in a timely manner.

Comparison between other auxiliary examinations and ultrasonic scanning

In addition to ultrasound scanning, the diagnosis of liver diseases in children can also be achieved through other auxiliary examination methods, such as CT scanning, MRI, liver function examination, etc. Compared to these methods, medical ultrasound scanners have the following advantages:

1. Non invasive: Ultrasound scanning does not require the use of radiation or injection of harmful substances, and will not cause any pain or adverse reactions to children, especially suitable for young children.

2. Real time: Ultrasound scanning can display changes in liver structure and function in real time, providing doctors with timely and accurate diagnostic information.

3. Low cost: Compared with other imaging examinations, ultrasound scanning equipment is relatively inexpensive, easy to operate, and has low maintenance costs, bringing convenience to medical institutions and patients.

Conclusion: The role of medical ultrasound scanners in the diagnosis of liver diseases in children cannot be ignored. Its non-invasive, real-time, and low-cost advantages make it one of the important tools for pediatricians. With the continuous progress of medical technology, it is believed that medical ultrasound scanners will play an increasingly important role in the diagnosis and treatment of liver diseases in children.
