Hepatic hemangioma is a common liver tumor in children, which is formed by the proliferation of liver vascular endothelial cells. The early symptoms of liver hemangioma in children are often not obvious, but it has a certain degree of harm, so early diagnosis is very important. Medical ultrasound scanners, as a non-invasive and reusable diagnostic tool, have a wide range of applications in the diagnosis of liver hemangiomas in children. This article will introduce the application of medical ultrasound scanners in the diagnosis of liver hemangiomas in children.

Medical ultrasound scanners generate real-time images by transmitting high-frequency ultrasound into human tissues and receiving echoes from different depths. In the diagnosis of liver hemangioma in children, ultrasound scanning can help doctors observe the size, shape, internal structure, and blood flow of the tumor, thereby determining the nature of the lesion.

Children usually need to maintain an empty stomach before undergoing ultrasound examination. The doctor will require the child to lie on the examination bed and expose their abdomen. Next, the doctor will apply transparent gel to the child's abdomen and wear gloves. The doctor will use a probe to transmit ultrasound to the child's abdomen, and then observe the liver and lesions on the image.

In ultrasound images, liver hemangiomas in children typically exhibit circular or elliptical abnormal echogenic areas. Doctors can determine the type of lesion by observing its internal structure. For example, benign masses typically exhibit uniform internal echoes, while malignant masses typically exhibit uneven echoes or regional echogenicity.

In addition to observing the morphology and internal structure of tumors, ultrasound examination can also evaluate the blood flow status of tumors. Doctors can use color Doppler ultrasound technology to display the blood flow inside tumors. In pediatric liver hemangiomas, abnormally rich blood flow signals are usually observed, which helps to further confirm the malignancy of the tumor.

The application of medical ultrasound scanners in the diagnosis of liver hemangiomas in children has many advantages. Firstly, it is a non-invasive examination method that will not cause any harm to children. This is particularly important for children, as their bodies are more fragile. Secondly, ultrasound scanning is a real-time imaging technique that allows doctors to immediately obtain images and perform accurate evaluations. In addition, ultrasound examination can also provide blood flow information in diagnosis, thereby better helping doctors understand lesions.

However, medical ultrasound scanners also have some limitations in the diagnosis of liver hemangiomas in children. Due to the limitations of ultrasound transmission, the examination results are influenced by factors such as abdominal fat and gas in children. In addition, in some cases, ultrasound images may not match other examination results, and further examination may be necessary to confirm the diagnosis.

In summary, medical ultrasound scanners have a wide range of applications in the diagnosis of liver hemangiomas in children. It is a non-invasive and reusable examination tool that can provide real-time images and blood flow information, helping doctors accurately evaluate lesions. For children suspected of having liver hemangioma, ultrasound examination is an ideal initial screening method. Through early detection and diagnosis, we can take corresponding treatment measures in a timely manner to ensure the healthy growth of children.
