Ultrasound: Your Safe and Effective Choice of Imaging

kidney scan

Ultrasound is an imaging test that is non-invasive, needleless, pain-free, and completely safe. It allows visualisation of the internal soft body organs using high-frequency sound waves.

An ultrasound is used to visualise areas of the body that require monitoring or diagnosing.


It’s fuss-free!

  • For abdominal/liver ultrasounds: you must fast for at least 4 hours before your ultrasound appointment.
  • For pelvic ultrasounds: drink 100-200ml of fluid 1 hour before your appointment for a full bladder prior scan.

No preparations are required for other types of ultrasounds.


On the day of the ultrasound, you will be guided to a procedure room with the ultrasound machine and transducer/probe. You are advised to lie down (on your back) on an examination bed.

The ultrasound sonographer will apply a gel over your skin on the body area that is to be tested. The sonographer will then hold the ultrasound probe over the gel to obtain images of your body part. Sometimes, the sonographer will ask you to hold your breath or stay still for a few seconds to obtain accurate images for the scan. At the end of the ultrasound test, your sonographer will clean off the gel over your skin, and you should be done. 

Expected duration of procedure

20-30 minutes in general

In more complex situations, your sonographer may spend longer to obtain relevant images of your ultrasound.
