Ultrasound scan

What is an ultrasound scan?

Ultrasound uses high frequency sound waves to create pictures of the inside of the body.

It can show internal organs as well as blood flow, and as a result ultrasound is used to look for any changes in organs and tissue.

Having an ultrasound

For an ultrasound scan you will be asked to lie on a table, usually facing upwards. A clear gel will be applied to the area of the body being examined, which helps the machine to make secure contact with the body. The radiographer will move part of the machine over the area of interest to get a picture.
