What is Ultrasound?

Ultrasound imaging uses high frequency sound waves to create an image of the structures being examined. A small transducer is placed against the patient’s skin allowing imaging of the underlying structure.

Ultrasound imaging can be performed for a variety of reasons and on numerous parts of the body. Organs such as the liver, kidneys and gallbladder can be demonstrated as well as obstetrics, blood vessels, muscles and soft tissues. Ultrasound can aid in interventional procedures such as breast biopsies and joint injections.

Things to Know

A referral and appointment are required for Ultrasound examinations. Please ensure you bring this with you to you on the day of your examination.

Preparation may be required, fasting or drinking water, you will be advised of this when making your booking. Some examinations require no preparation.

A sonographer will perform your Ultrasound scan. Generally, an Ultrasound scan takes around 30 mins, this may vary depending on the structure being imaged. You may be required to change into a disposable gown for the scan. During the scan a water-soluble gel will be applied to the skin to aid transmission of sound waves from the transducer through the skin into the organs. You may be asked to hold your breath and roll onto your side at times throughout the scan.
