Ultrasound uses high frequency sound waves to create images of internal body structures.

Ultrasound is non invasive and does not use radiation.

An ultrasound scan typically takes 30 to 60 minutes dependent on the specific referral.

The examination is performed by a trained professional called a sonographer who as part of the examination will apply a clear gel to the area being examined and move a handheld transducer to obtain the necessary images.  You will feel pressure from the transducer, but ultrasound is usually painless.  During the examination you may be asked to change positions or hold your breath.

Certain examinations require preparation, such as fasting or having a full bladder; you will be given the preparation instructions for your scan when your appointment is made.
