The liver is one of the most important organs in the human body, responsible for many important physiological functions, including metabolism, detoxification, and protein synthesis. Liver lesions refer to structural or functional abnormalities that occur in liver tissue, including cirrhosis, liver fibrosis, liver cancer, etc. In order to detect and treat liver lesions early, medical ultrasound scanners have been widely used in the medical community for liver detection. This article will explore the value of medical ultrasound scanners in detecting liver lesions.

1、 The principle of ultrasonic scanner

Medical ultrasound scanner is a non-invasive imaging device that utilizes the propagation and reflection characteristics of ultrasound in human tissues to capture images. Ultrasound is a high-frequency sound wave that can propagate at high speeds in human tissues and be reflected and scattered by different structures within the tissue. Different organizational structures have different scattering characteristics on the echo of ultrasound, resulting in different images. Ultrasonic scanners send and receive ultrasonic pulses, and then use computers to process data and generate images. Ultrasound has become an indispensable tool in Medical imaging because of its advantages of non radiation, painless and non-invasive.

2、 Application of ultrasound scanner in liver disease detection

1. Liver structure detection

Ultrasound scanners can help doctors detect liver structure. The normal liver is nodular, while liver lesions may lead to changes in liver structure. Through an ultrasound scanner, doctors can observe the size, shape, and edge of the liver to determine whether there are liver lesions. For example, liver cirrhosis can cause unevenness on the surface of the liver, while liver cancer may lead to changes in liver morphology. Ultrasound scanners can help doctors quickly and accurately detect these lesions.

2. Liver hemodynamic detection

The liver is the largest internal organ in the human body, with abundant blood supply. Liver lesions may lead to changes in hemodynamics, including dilation or contraction of liver blood vessels, vascular blockage, etc. Ultrasound scanners can detect the hemodynamic status of the liver through blood flow imaging. By observing blood flow velocity, vascular morphology, and vascular blockage, doctors can determine the type and degree of liver lesions and take corresponding treatment measures in a timely manner.

3. Qualitative and quantitative evaluation of liver lesions

Ultrasound scanners can help doctors qualitatively and quantitatively evaluate liver lesions. By observing the echo characteristics and morphological changes of liver lesions, doctors can determine the nature of the lesions, such as fatty liver and liver cysts. In addition, ultrasound scanners can also assess the severity and prognosis of lesions by measuring their size, shape, and blood flow.

3、 Advantages and disadvantages of ultrasonic scanners

1. Advantages

Ultrasonic scanners have the advantages of no radiation, no pain, and no trauma, and will not cause any harm to patients. Compared with other imaging technologies, ultrasound scanners are inexpensive and easy to promote and use. In addition, ultrasound scanners can detect liver lesions in real-time mode, allowing doctors to immediately observe the images, helping to quickly diagnose and treat liver lesions.

2. Disadvantages

Ultrasound scanners have limitations in depth and depth, and their detection performance in the deep abdominal cavity and lungs is not as good as CT and MRI. In addition, the poor image quality of ultrasound scanners for obese patients limits their application in obese populations.

Conclusion:

Medical ultrasound scanners have important value in detecting liver lesions. Through liver structure detection, hemodynamic detection, and qualitative and quantitative evaluation, ultrasound scanners can help doctors detect and treat liver lesions early. However, ultrasound scanners also have some limitations, including limitations in depth and depth, and image quality issues for obese patients. With the continuous progress of technology, the application of ultrasound scanners in liver disease detection will be further expanded.
