1. Application of Ultrasound in Various Subjects

The application of ultrasound technology in modern medicine extends far beyond prenatal testing, making it an essential diagnostic tool in many medical fields. Below, we will delve into the application scenarios of ultrasound in various fields.

1. Abdominal ultrasound: diagnosis of diseases of the hepatobiliary, gastrointestinal and urinary systems

Abdominal ultrasound is one of the preferred methods for diagnosing diseases of the hepatobiliary, gastrointestinal and urinary systems. Using ultrasound, doctors can clearly observe the structure and morphology of organs such as the liver, gallbladder, pancreas, and spleen, and detect the presence of tumors, stones, and inflammation. For example, common diseases such as fatty liver, gallstones and kidney stones can be diagnosed immediately with an abdominal ultrasound. In Hong Kong,It is about HK$800-1500, and the specific price depends on the level of the medical facility and the advanced level of equipment.

In addition, ultrasound of the urinary system can help diagnose hydronephrosis, bladder tumors and other problems. During the procedure, the position of the probe is adjusted to the shape of the patient's body to obtain the best image.

2. Cardiac ultrasound: assessment of heart function, diagnosis of valvular heart disease

Cardiac ultrasound, also known as color ultrasound, is an important tool for assessing heart function. It allows you to see the contraction and relaxation of the heart in real time, which can help doctors diagnose cardiomyopathy, valvular heart disease, or congenital heart disease. For patients with chronic diseases such as high blood pressure or diabetes, regular cardiac ultrasounds can help detect heart disease early.

3. Vascular ultrasound: diagnosis of arteriosclerosis, varicose veins

Vascular ultrasound is primarily used to assess the health of arteries and veins. For example, carotid ultrasound can detect atherosclerotic plaques and prevent the risk of stroke. Ultrasound examination of the veins of the lower extremities can diagnose varicose veins or deep vein thrombosis. The test is non-invasive and non-radiological and therefore suitable for long-term monitoring of vascular lesions.

4. Musculoskeletal ultrasound: diagnosis of arthritis, tendonitis

Musculoskeletal ultrasound is widely used in sports medicine to clearly visualize the structure of muscles, tendons, ligaments, and joints. For general arthritis of the frozen shoulder, lateral elbow, or knee, ultrasound can accurately identify the lesion and guide the development of a treatment plan.

5. Breast ultrasound: screening for breast tumors, identification of cysts

Breast ultrasound is an important method for screening for breast diseases, especially in young women and dense breast tissue. They can distinguish between cysts and solid tumors and perform a needle biopsy to further confirm the diagnosis.

2. Ultrasonic Guides: Sharp Tools for Precision Machining

Ultrasound is not only used for diagnosis but also as an adjunctive tool for treatment, improving the accuracy and safety of treatment.

1. Puncture and Aspiration: Extraction of Fluid and Tissue Samples for Examination

Under ultrasound guidance, the doctor can accurately identify the lesion and perform a needle aspiration or biopsy. For example, liver biopsy is the gold standard for diagnosing liver fibrosis and liver cancer, and ultrasound guidance can significantly reduce the risk of puncture.

2. Injection Therapy: Injecting medication precisely to reduce pain

For patients with arthritis or tendonitis, ultrasound-guided drug injections ensure precise delivery of drugs to the injured site, improving efficiency and reducing side effects. This approach is widely used for pain management.

3. Tumor ablation: uses ultrasound energy to destroy tumor tissue

High-intensity focused ultrasound (HIFU) is a non-invasive tumor treatment technique that focuses ultrasound energy on tumor tissue, causing it to heat and necrosis. This method is suitable for the treatment of uterine fibroids, prostate cancer and other diseases.

3. New Ultrasonic Technologies

With the advancement of science and technology, ultrasound technology continues to innovate, further increasing the possibilities for clinical diagnosis and treatment.

1. Elastic Ultrasound: Assesses tissue stiffness and aids in diagnosing things like liver fibrosis or breast cancer

Elastic ultrasound (e.g., FibroScan) can quantify tissue stiffness and is used to assess the degree of liver fibrosis or the benign or malignant nature of breast tumors. This technique eliminates the need for puncture and greatly improves patient acceptance.

2. Echocardiography: Improves image contrast and diagnostic accuracy

Ultrasound contrast improves the display of blood flow signals by injecting microbubble contrast agents suitable for liver tumor assessment and myocardial perfusion. Its accuracy is comparable to CT and MRI without the risk of radiation.

3. Focused Ultrasound: Uses high-intensity ultrasound for non-invasive procedures

Focused ultrasound (e.g., MRgFUS) is a non-invasive treatment technique used to treat uterine fibroids, bone metastases, and other diseases. Patients do not require surgery and have a short recovery time.

4. Advantages and Limitations of Ultrasound

While ultrasonic technology is widely used, it still has some advantages and limitations.

1. Advantages: Non-invasive, radiation-free, immediate, convenient

Ultrasound does not require incisions or radiation and is suitable for special groups, such as pregnant women and children. Additionally, real-time imaging capabilities allow doctors to dynamically observe organ function.

2. Limitations: Affected by recipient type and low bone penetration

The image quality of the ultrasound is affected by the patient's physique, and obese people may experience blurry images. In addition, ultrasound is difficult to penetrate into organs that contain bones and gas (e.g. lungs).

5. Future Developments in Ultrasound

Future developments in ultrasound technology will further expand its range of applications and diagnostic and therapeutic value.

1. AI-Assisted Diagnostics: Enhancing Diagnostic Efficiency and Accuracy

AI technology automatically analyzes ultrasound images, quickly identifying lesions and reducing human error. Some private hospitals in Hong Kong have started piloting AI-assisted systems.上腹超聲波價錢

2. Micro ultrasound: used for endoscopy and vascular intervention

The advent of ultrasound microprobes has made it possible to incorporate ultrasound microprobes into endoscopes and catheters for more advanced examinations and treatments.

3. Remote Ultrasound: Solving the Problem of Scarcity of Medical Resources in Remote Areas

Through 5G networks, ultrasound images can be transmitted to professionals in real-time for remote diagnosis, improving access to healthcare in remote areas.超聲波師
