What Is a General Ultrasound?
A general ultrasound, also known as diagnostic or abdominal ultrasound, is a non-invasive imaging technique used to visualize the internal organs and structures of the body. It works by using high-frequency sound waves to create images of the inside of the body. The sound waves are emitted by a probe, and as they bounce off tissues and organs, they are captured and translated into real-time images displayed on a screen. General ultrasounds are commonly used to assess conditions in the abdominal area, such as problems with the liver, kidneys, gallbladder, spleen, pancreas, and reproductive organs.
The procedure is typically performed in a hospital or outpatient setting and does not require any special preparation in most cases, although certain conditions, like a full bladder for pelvic ultrasounds, may require specific instructions. During the procedure, the patient is usually asked to lie on an exam table, and a gel is applied to the area being examined to improve the sound wave transmission. A technician, or sonographer, moves the ultrasound probe across the skin to capture the necessary images. Ultrasound imaging is often used to detect abnormalities such as tumors, cysts, infections, or inflammation. It is a preferred diagnostic tool because it is quick, non-invasive, and free of radiation, making it suitable for use in a variety of clinical settings.
