What is an Ultrasound?

Ultrasound has been utilised in the medical imaging industry for over 40 years. In this time vast improvements have been made to improve the image quality of this modality. The images are created using high frequency sound waves, making it a very safe and commonly used modality which is excellent for assessing soft tissue structures. Ultrasound has superb image resolution and can view abnormalities as small as 1mm.  It is also an outstanding modality for performing a large variety of soft tissue and joint injections.

How is an ultrasound performed?

An ultrasound scan is a very simple procedure for the patient. A small amount of ultrasound gel is placed on your skin and the ultrasound transducer moves over your skin. There is no pain or discomfort for this test. The sonographer may ask you to move the area that is being scanned to watch the anatomy move on the screen. The images are reviewed by the Radiologist who may come in to see you also. An ultrasound usually takes no longer than 30 minutes with a report from the Radiologist then sent to your referring healthcare professional within 24hrs.  Your results are best discussed with your healthcare professional who can answer all your questions about diagnosis and treatment.

Are there any risks?

There are no known harmful effects of an ultrasound.

Are there any limitations?

Ultrasound waves do not pass easily through bone and air. Additional tests such as an X-ray may be needed to view bones. Intestinal gas can limit views of deeper structures such as the pancreas.


For all scans please wear comfortable loose fitting clothes.
