An ultrasound scan, sometimes called a sonogram, is a procedure that uses high-frequency sound waves to create an image of part of the inside of the body.

An ultrasound scan can be used to monitor an unborn baby, diagnose a condition, or guide a surgeon during certain procedures. A small device called an ultrasound probe is used, which gives off high-frequency sound waves.

You can't hear these sound waves, but when they bounce off different parts of the body, they create "echoes" that are picked up by the probe and turned into a moving image.

This image is displayed on a monitor while the scan is carried out. Most ultrasounds take around 30 minutes to perform, however more complex scans can take more than an hour and you will be advised of this at time of booking. When scheduling your ultrasound, you will be informed of any preparation for your exam.
