WHAT IS AN ULTRASOUND (SONAR) EXAMINTION?

• A type of medical imaging where high frequency sound waves are used to produce images of the body structures.
• The examination is done in real-time, making it possible to evaluate movement.
• Doppler is a special ultrasound technique which evaluates blood flow through a blood vessel. It can diagnose thrombosis and occlusion or narrowing of blood vessels.
• Ultrasound does not use ionising radiation and is therefore safe to use in pregnancy.
