Childhood heart disease is a common pediatric heart disease that requires accurate diagnosis and timely treatment. Medical ultrasound scanners, as a common and effective cardiac examination tool, are widely used in the diagnosis of pediatric heart disease. This article will introduce the application of medical ultrasound scanners in the diagnosis of pediatric heart disease, and explore their advantages and future development directions.

1、 The principle and basic working mode of medical ultrasound scanners

Medical ultrasound scanners utilize the characteristics of ultrasound to obtain medical images. It emits high-frequency ultrasound through an external sensor into the patient's body, then receives the reflected acoustic signal from the body, and finally generates two-dimensional, three-dimensional, or four-dimensional images through signal processing and image reconstruction algorithms. Medical ultrasound scanners are non radioactive, non-invasive, safe, convenient, and real-time, making them the preferred tool for diagnosing heart disease in children.

2、 Application of medical ultrasound scanner in the diagnosis of pediatric heart disease

1. Evaluation of cardiac structure: Medical ultrasound scanners can clearly and accurately display the anatomical structure of children's hearts, including cardiac cavity size, cardiac wall thickness, valve morphology and function, etc. By analyzing these features, it can be determined whether the patient has congenital malformations, cardiac dilation, abnormal cardiac wall thickness, and other pathological changes.

2. Cardiac function evaluation: Medical ultrasound scanners can observe the contractile and diastolic processes of the heart in real-time, evaluate the functional status of the heart, including systolic function, valve movement, intracardiac blood flow velocity, etc. This is of great significance for determining the severity of pediatric heart disease and selecting treatment plans.

3. Congenital heart defect screening: medical ultrasonic scanner can screen Congenital heart defect in infancy. By examining the structure and function of the heart, hidden Congenital heart defect can be found early, which is conducive to timely intervention and treatment and reduces the risk of complications for patients.

4. Preoperative evaluation of cardiovascular surgery: For pediatric patients who require cardiovascular surgery, medical ultrasound scanners can provide preoperative evaluation, including analysis of hemodynamic parameters, cardiac structure and function, etc. This can not only help surgeons make surgical plans, but also predict the postoperative outcomes.

3、 The advantages of medical ultrasound scanners in the diagnosis of pediatric heart disease

1. Non invasive: Compared with traditional cardiac examination methods, medical ultrasound scanners do not require puncture operations, avoiding the risks of trauma and infection brought about by traditional examinations, and are safer for children and patients.

2. Real time: Medical ultrasound scanners can observe the structure and function of the heart in real time, and can detect abnormalities in real-time during the examination process, improving the accuracy and timeliness of diagnosis.

3. Easy to operate: Medical ultrasound scanners are easy to operate, do not require special training to master, and can be used at the bedside for continuous monitoring and follow-up.

4、 The development direction of medical ultrasound scanners in the diagnosis of pediatric heart disease

1. 3D ultrasound: Currently, the mainstream technology for medical ultrasound scanners is 2D ultrasound, but its resolution and anatomical display capabilities still have limitations. In the future, with the further development of technology, three-dimensional ultrasound technology is expected to be applied in the diagnosis of pediatric heart disease, improving image quality and diagnostic accuracy.

2. contrast-enhanced ultrasound: Combining contrast-enhanced ultrasound with ultrasound contrast agents can provide clearer blood flow images, which is of great significance for evaluating intracardiac blood flow velocity and thrombosis. This technology has potential for development in the diagnosis of pediatric heart disease.

3. Cardiac tissue elastography: Cardiac tissue elastography is a technology that can measure the hardness of cardiac tissue, which is of great significance for evaluating myocardial function and fibrosis degree. It has broad application prospects in the diagnosis and treatment of pediatric heart disease.

Medical ultrasound scanners play a crucial role in the diagnosis of pediatric heart disease. It provides detailed cardiac structure and functional information in a non-invasive and real-time manner, providing strong support for doctors to make accurate diagnoses and develop personalized treatment plans. With the continuous progress and innovation of ultrasound technology, the application of medical ultrasound scanners in the field of pediatric heart disease will become increasingly widespread and provide better medical services for pediatric patients.
