Ultrasound or ultrasound is a type of harmless technique. It uses high-frequency sound waves to observe organs and structures inside the body. Health professionals use them to view the heart, blood vessels, kidneys, liver, and other organs. During pregnancy, doctors use ultrasound tests to
observe the fetus. Unlike x-rays, ultrasound does not expose radiation.
During the test, you lie on a table. A special technician or doctor moves a device called a transducer over a part of the body. The transducer sends sound waves that bounce off tissues inside the body. The transducer also captures the bouncing waves. The ultrasound machine creates the images of these sound waves.
Depending on the part of the body to be studied, you will lie down or sit on a stretcher. There are even scans that are done standing up.
The region to be explored will be fully discovered. A conductive gel is applied to the skin, which can sometimes feel cold. Depending on the type of test, you may be asked to hold your breath for short intervals of time.
In abdominal ultrasounds, fasting for 6 hours (allowed to drink water on demand)
In patients operated on for gallbladder (cholecystectomized), fasting time is NOT necessary.
In abdominal urological and gynecological ultrasounds, you will be asked to drink 1 liter of water, 1 hour before the test (to have a full urinary bladder).
