Ultrasound imaging (also called ultrasound scanning or sonography) is a non-invasive medical examination that uses high frequency sound waves to produce images of the inside of the body. This enables doctors to diagnose and treat a wide range of medical conditions.

 Some of the major advantages of ultrasound include:

  • it is a simple and non-invasive procedure
  • it can show the structure and movement of the body's internal organs, as well as blood flowing through blood vessels in real time
  • side effects are negligible and no radiation is involved

Ultrasound examinations are performed at the following Global Diagnostics locations:

Before your ultrasound

A referral from your doctor and an appointment are required for an ultrasound examination. Depending on the type of examination you may be asked to fast from food and fluids. Some examinations will require you to drink a specific amount of water prior to arriving so that your bladder is full. You will be advised of the appropriate preparation when you make your appointment.

At Global Diagnostics, ultrasound examinations are carried out by a sonographer (a technologist trained in ultrasound imaging and accredited by the Australian Sonographer Accreditation Registry - ASAR), and the scans are interpreted by a radiologist (a medical doctor specializing in the interpretation of medical images).

During your ultrasound

During the examination a water based gel will be applied to the skin over the area to be scanned to improve the transmission of sound waves between the body and the ultrasound transducer. To get the best possible images the sonographer may ask you to hold your breath or move your position so the best images can be obtained.

On occasion, a radiologist may need to speak with you and perform some ultrasound scanning as well, in order to clarify what has been shown in the images and ensure the question asked by your referring doctor is answered accurately.
