Ultrasound uses sound waves, not radiation to produce images. During an ultrasound examination, a sonographer will apply gel to the area of interest and then will move a handheld transducer over the skin surface.
You may be asked to fast from midnight or drink a litre of water an hour before your scan. If you are a diabetic you need to inform reception so they can schedule a morning appointment for you.
Ultrasound is also useful for the detection of deep vein thrombosis and many vascular studies are undertaken using ultrasound.
