What is Ultrasound Scanning?

Ultrasound (US) scanning is an investigation to “see” the inside of the human body through high-energy sound waves. The sound waves are recorded and displayed as a real-time visual image. No radiation is involves in ultrasound scanning.

What are some common uses of Ultrasound Scanning?

Ultrasound scanning is a way to examine many parts of the body like hamstring (thigh), or pelvis. It can be used to investigate shoulder joints as well. As ultrasound images are captured in real-time, they can show movement of internal tissues and organs, and enable blood flow visualisation. Doppler ultrasound is a special technique used to examine blood flow which investigates blockages to the blood flow, such as deep vein thrombosis.

How should I prepare for Ultrasound Scanning?

Wear comfortable or loose-fitting clothes. Special instructions may be given to some patients going for ultrasound scanning for some regions. Listen to your doctor’s advice.

How is Ultrasound Scanning performed?

You will lie on your back on the examination table.

A clear gel is applied to your body in the area to be examined, and a transducer is pressed against your body to acquire the desired images. The radiographer will sweep the transducer back and forth to image the area of interest. The sound waves produced by the transducer cannot penetrate air, so the gel helps eliminate air pockets between the transducer and the skin. The gel is water soluble, safe and harmless and can be easily wiped off your skin with a paper towel.

For pelvic ultrasound, it may be done abdominally (transabdominal).

When the examination is completed, the patient will be asked to dress and wait while the ultrasound images are reviewed by our radiologist.
