Ultrasound Services

At Western Radiology we perform a variety of ultrasounds, dependant on your medical needs.


Ultrasound examinations use high frequency sound waves to look inside the body. The sound waves emitted are so high that the human ear cannot hear them. The sound waves are directed at the internal body part from a small, vibrating crystal in a hand-held scanner (called a transducer). A gel is also used on the skin to form acoustic interface with the probe. The scanner reflects the sound or 'echoes' to create an image. The quality of an ultrasound image is lower than that of a CT scan but it is non-invasive, completely safe and doesn't involve radiation. It is commonly used to study the abdominal organs, pelvic organs and breast tissue.

A Doppler Ultrasound is where a special probe is applied with mild to moderate pressure against the leg, or over any areas where veins/ arteries are found. A gel is also used on the skin to form acoustic interface with the probe. A specifically trained Sonographer will then use the ultrasound machine to obtain scans which show blood flow as colour images based on the speed and direction of blood flow. Images are usually in black and white but a Colour-flow Doppler will show blood flow as blue or red  areas. In some cases patients may find ultrasound uncomfortable over tender areas.

The Duplex Ultrasound is a vascular ultrasound procedure used to assess blood flow and the structure of leg veins. The term "duplex" refers to the fact that two modes of ultrasound are used — Doppler and B-mode. The B-mode transducer (like a microphone) obtains an image of the vessel being studied. The Doppler probe within the transducer evaluates the velocity and direction of blood flow in the vessel.
