Frequently Asked Questions

An ultrasound scan uses high-frequency sound waves (inaudible to humans) to create images of the inside of the body. Ultrasound is sent into the body and bounces back (or echoes) off the different tissues it passes through. This echo gives the ultrasound image its features, with varying shades of grey representing different densities. Ultrasound is safer than an X-Ray because it uses sound waves, instead of radiation. For this reason, it is commonly used to evaluate fetal development during pregnancy. ​ Ultrasound can also detect problems in the liver, heart, kidney, or abdomen. As it generates a real time moving image, it is particularly useful in the diagnosis of circulatory problems, i.e. blood flow through your arteries and veins. This is known as a Doppler ultrasound. ​ The person who performs an ultrasound scan is called a sonographer. Ultrasound images are usually interpreted by radiologists, cardiologists, or other specialists who then reports these findings to the referrer to discuss with the patient.

Ultrasound involves the use of sound waves to produce images inside the body and because it is in real-time, can be used to view movement as well as anatomical structures. Ultrasound is used to examine pregnancies as well as internal organs such as the kidneys, pancreas, liver, testes, ovaries and the thyroid gland. It can also help diagnose issues with soft tissues, tendons, muscles, and blood vessels. The images produced during the scan are analysed by the Sonographer, then reported on by the Radiologist with the final report being sent to the requesting doctor.

You would usually be referred by your medical practitioner, however, in some instances where medically warranted, you may be able to self refer. If you have medical insurance, you may need a referral for reimbursement. We recommend speaking directly to your insurance company.

For an external ultrasound, the sonographer puts a gel onto the patient’s skin and places the transducer onto the skin. The transducer is moved over the part of the body that needs to be examined. Sometimes an internal examination is required to further assess the female pelvis and pregnancies. If this is required this will only be performed with patient informed consent.

Doppler ultrasound is used to measure blood flow and reveal any obstructions.

Most scans take between 15-40 minutes. Timing is dependent on the area being scanned.
