Ultrasound Investigation
Ultrasound Procedure
Ultrasound Preparation


Ultrasound imaging, also called ultrasound scanning or sonography, is a method of 'seeing' inside the human body through the use of high frequency sound waves. It is a useful way of examining many of the body's internal organs non-invasively and without any discomfort.

The use of ultrasound has been deemed safe even for pregnant women. There is no ionizing radiation involved and no known long-term or short term effects. Currently ultrasound service is available in Ang Mo Kio Polyclinic, Yishun Polyclinic, Choa Chu Kang Polyclinic and    Ang Mo Kio- Thye Hua Kwan Hospital. All the ultrasound examination requires advance booking with our centres

A water-soluble gel will be applied over the area to be examined to optimize transmission of the sound waves through the body.
