Ultrasonic scanner is a noninvasive examination technique widely used in clinical practice, which has high accuracy and reliability in the diagnosis of liver diseases. This article will describe the application of medical ultrasound scanners in the diagnosis of liver diseases.

1、 The principle of medical ultrasonic scanner

Medical ultrasound scanner is a medical device that images images based on acoustic principles. It emits ultrasound waves into the interior of the human body, detects and records reflected echoes between different tissues, and then uses a computer to process these echo signals to form images. Compared with traditional X-ray examination, ultrasound examination does not require the use of radioactive substances and does not cause any harm to the human body, so it is widely used in clinical practice.

2、 Application of medical ultrasound scanner in diagnosis of liver diseases

Diagnosis of liver cancer: Liver cancer is one of the most common malignant tumors of the liver. Its early symptoms are not obvious and often need to be detected through examination. Ultrasound scans can clearly display the structure of the liver and help doctors detect liver cancer and its metastases. Ultrasound can also assess important information such as the size, location, number, and blood supply of tumors.

Diagnosis of liver cyst: Liver cyst is a common benign liver lesion, commonly seen in middle-aged and elderly people. Ultrasound scanning can clearly display the size, number, location, and morphology of intrahepatic cysts, helping doctors make a correct diagnosis.

Diagnosis of liver cirrhosis: Liver cirrhosis is a chronic liver disease characterized by fibrosis, structural disorder, and impaired function of the liver. Ultrasound can directly observe the structure and density of liver tissue, which can help doctors accurately assess liver stiffness and fibrosis, thereby determining the degree and prognosis of cirrhosis.

Evaluation of liver function: Ultrasound can also evaluate the function of the liver, including the size of the liver, the patency of intrahepatic pipelines, and the speed of bile flow. These indicators can reflect the health status of the liver and help doctors determine the type and severity of liver diseases.

3、 Advantages of medical ultrasound scanners in the diagnosis of liver diseases

Non invasive: Ultrasound scanning is a non invasive examination method that does not require puncture or injection of large doses of radioactive substances, and does not cause any harm to the patient.

Ease of operation: Ultrasound scanning is simple and fast, requiring only patients to lie on the examination bed and be scanned by professional medical personnel through ultrasound probes.
