Tests and Treatments
Ultrasound
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.
