Video of patient experience in Ultrasound

Ultrasound is a painless and safe imaging technique that does not involve the use of x-rays or ionising radiation and does not require any injections.

Ultrasound is used to visualise and assess a variety of internal structures and organs in the body as well as smaller superficial structures such as tendons. Examination of pregnancies, liver and gall bladder, renal tract, thyroid, abdomen, pelvis, breast and testes are some of the more common examination requests. It is also frequently used for guidance for interventional procedures such as biopsy or the location of foreign bodies.

In obstetric patients ultrasound is used to determine the status of a pregnancy and assess the health and development of the foetus. An ultrasound transducer, a hand held device to which a water based gel is applied to achieve contact with the skin, is placed over the area being examined. Sound waves are emitted from the transducer into the part being examined and the reflected sound waves are analysed by a computer and turned into images.

In some cases better images can be obtained with the use of an internally placed transducer. This will be discussed with the patient at the time of examination and written patient consent will be obtained prior to commencement. If you feel you would like a chaperone, this can also be arranged.

  • Transvaginal ultrasound is a type of pelvic ultrasound. It is used to look at a woman's reproductive organs, including the uterus, ovaries and cervix


Doppler ultrasound is a non-invasive test used to evaluate the flow of blood in arteries and veins. High frequency sound waves are pulsed into the blood vessels. The flow of blood alters the frequency of the reflected sound waves and this change is analysed by a computer and a calculation made about the speed and direction of the blood flow.

Doppler produces a very distinctive, pulsating sound that may be audible to the patient.

It is an effective tool for diagnosing blocked or constricted arteries.
