An Ultrasound scanner does not use X-Rays (ionising radiation).
The ultrasound probe emits high frequency sound waves that are passed through your body. As they are reflected back by the structures inside, the echoes are used to form an image.
Doppler ultrasound is an additional technique that can be used to examine blood vessels to provide both structural and functional information.
Ultrasound is a relatively patient friendly way of imaging and no harmful effects have been found.
Depending on the type of examination you are having you may need to prepare, for example by fasting or filling your bladder. If any preparation is required, a member of staff will contact you with specific instructions.
Contraindications are reasons why an ultrasound examination may not be undertaken. There are no medical conditions that would make having an ultrasound unsuitable.
