What is an ultrasound?
An ultrasound scan is a medical test that uses high-frequency sound waves to capture live images from the inside of your body. It’s also known as sonography.The technology is similar to that used by sonar and radar, which help the military detect planes and ships. An ultrasound allows your doctor to see problems with organs, vessels, and tissues without needing to make an incision.Unlike other imaging techniques, ultrasound uses no radiation. For this reason, it’s the preferred method for viewing a developing fetus during pregnancy.
Ultrasound Procedure
Ultrasound is a medical procedure that uses sound waves to create images of the inside of the body. It is used in the assessment of a variety of conditions, including pregnancy, heart disease, and organ damage. The ultrasound probe is placed on the skin, and the sound waves bounce off the structures inside the body. The image is then displayed on a monitor, providing information about the size, shape, and location of the structures. Ultrasound is a safe and painless procedure that can be used to diagnose a variety of conditions.
Why Choose Saami Scans?
Things to consider before taking an Ultrasound Scan:
Before the scan, you will likely be asked to drink plenty of water so that your bladder is full. This is because a full bladder helps to produce clearer images. You may also be asked to avoid eating or drinking for a few hours before the ultrasound so that your stomach and intestines are empty. This is because ultrasound images can be obscured by gas or stool in the intestines. During the ultrasound, you will lie on a bed and a gel will be applied to your skin. A small device called a transducer will be moved over your body, sending out sound waves that create pictures on a screen. The whole process usually takes less than 30 minutes. There is no radiation involved in ultrasound, so it’s generally considered safe for both adults and children.
