What is Ultrasound? Mechanism of Action and Medical Applications
What is Ultrasound?
Ultrasound is a safe, radiation-free imaging method that uses high-frequency sound waves to visualize the internal structures of the body. It is widely used in many medical fields, especially in obstetrics and gynecology.
How Does Ultrasound Work?
The ultrasound device sends high-frequency sound waves via a transducer, also known as a probe. These waves strike the tissues, reflect back, and are converted into an image by the device. Since different tissues reflect sound waves differently, detailed images are obtained.
Types of Ultrasound
The most commonly used types of ultrasound are; abdominal ultrasound, transvaginal ultrasound, Doppler ultrasound, and 3D/4D ultrasound. Each is used for different clinical purposes.
What is Doppler Ultrasound?
Doppler ultrasound is used to assess blood flow. It provides information about the direction and speed of blood within vessels. It is important in evaluating fetal circulation during pregnancy.
Advantages of Ultrasound
Its most important advantages are that it is radiation-free, safe, provides quick results, and is repeatable.
Use of Ultrasound in Obstetrics and Gynecology
It is used in pregnancy monitoring, fetal development assessment, and the evaluation of conditions such as ovarian cysts, fibroids, and endometriosis.
Applications in General Medicine
Ultrasound is also widely used in the evaluation of liver, kidney, gallbladder, thyroid, and vascular diseases.
Is Ultrasound Safe?
Ultrasound is considered safe because it does not contain ionizing radiation and can be easily used even during pregnancy.
Preparation Before Ultrasound
For some types of ultrasound, fasting or a full bladder may be required. This varies depending on the area to be examined.
When is Ultrasound Performed?
It is performed upon a doctor's recommendation in cases of pain, swelling, pregnancy monitoring, or suspected illness.
Conclusion
Ultrasound is an indispensable diagnostic tool in modern medicine. Due to its safety, speed, and effectiveness, it plays an important role in the early diagnosis of many diseases.
