Sonography
Sonography, also known as ultrasound imaging, is a medical diagnostic technique that uses high-frequency sound waves to create images of the inside of the body. Unlike other imaging techniques, sonography does not involve radiation, making it a safe and non-invasive procedure.
The process of sonography involves a device called a transducer, which emits sound waves and then receives the echoes that bounce back from tissues in the body. These echoes are converted into visual images displayed on a monitor, which can then be analyzed by healthcare professionals. Sonography is commonly used to examine various organs and structures within the body, including the heart, liver, kidneys, reproductive organs, and muscles.
One of the most well-known applications of sonography is in obstetrics, where it is used to monitor fetal development during pregnancy.
It can detect the baby’s heartbeat, estimate the due date, and identify any potential abnormalities or complications. Sonography is also widely used for diagnosing conditions like gallstones, liver disease, kidney stones, and certain types of cancer.
In addition to diagnostic uses, sonography can guide certain medical procedures, such as biopsies and injections, ensuring accuracy and minimizing risk. The technique is often preferred for its safety, real-time imaging, and ability to provide both structural and functional information about the body.
