Ultrasound
An ultrasound examination is undertaken by an ultrasonographer, and obtains images of the body without the use of x-rays.
It uses high frequency sound waves which pass through the skin and are reflected by the body’s internal organs. These ‘echoes’ are converted with the aid of a computer, into a picture onto a screen.
The examination involves ultrasound gel being spread over the area of interest and an ultrasound probe is then lightly pressed on the area. Depending on the type of scan you are having, these can take between 10 minutes up to 40 minutes. Some scans require preparation which could include having a special diet, having nothing to eat or drink or attending with a full bladder.
