Ultrasound scans are images of your internal organs created by using sound waves.
High frequency waves are directed at your body and then reflected (echoed) back to a scanner that creates an image of the area scanned.
What's it like?
- A special gel is spread on the skin over the area to be examined.
- This helps to define the area as clearly as possible by enhancing the transmission and reception of the sound waves.
- The ultrasound scanner looks like a small paint roller that the technician moves over the area to be scanned.
It is completely painless, but the gel can sometimes feel a bit cold.
There is generally nothing special that you have to do to prepare for an ultrasound and there are no side effects.
