ULTRASONOGRAPHY

Ultrasound, also known as ultrasonography, is a medical imaging technique that uses high-frequency sound waves to create images of the inside of the body. The sound waves bounce off tissues and organs, creating an image that can be used to diagnose and monitor a wide range of medical conditions.

During an ultrasound exam, a technician applies a gel to the skin and uses a handheld device called a transducer to send and receive the sound waves. The transducer converts the sound waves into images that can be viewed on a computer screen.

Ultrasound is a noninvasive and safe imaging technique that can be used to examine many parts of the body, including the abdomen, pelvis, heart, and blood vessels. It can also be used to guide certain medical procedures, such as biopsies and injections.

In obstetrics, ultrasound is commonly used during pregnancy to monitor fetal development and detect any abnormalities. It can also be used to determine the sex of the fetus and to estimate the due date.

Advances in technology have led to the development of 3D and 4D ultrasound, which provide more detailed images of the inside of the body. Ultrasound is an important tool in modern medicine and is used in many medical specialties, including obstetrics, cardiology, and radiology.
