Simple and Safe - High frequency sound waves are used to produce real time images for the body.

  • Images of the body structures (including organs, ligaments, tendons, muscles, and blood vessels) are obtained through specialised equipment using high frequency sound waves.
  • The examination is done in real-time, making it possible to evaluate movement.
  • Doppler is a special ultrasound technique which evaluates blood flow through a blood vessel to diagnose thrombosis, occlusion or narrowing of blood vessels.
  • Ultrasound does not use ionising radiation and is therefore safe to use in pregnancy.


  • You may be asked to change into a procedure gown for the procedure
  • The sonographer will move the probe over the area under investigation to obtain images in different planes.
  • Ultrasound gel is used for the probe to move over your skin, leaving your skin wet and sticky. This will be wiped off with paper towel after the procedure.
  • It is important to keep still once positioned and to listen to any instructions given by the sonographer during the procedure
  • The procedure may be uncomfortable or painful if you have suffered an injury.
  • The procedure may take between 15-30 minutes depending on the type of procedure.  The results will be ready within 30 minutes of the procedure being completed.  Your doctor will discuss the results with you.


  • You should bring a referral note from your doctor requesting the relevant ultrasound procedures based on your clinical history.
  • You do not need to make an appointment for an x-ray examination unless the procedure requires special preparation for which you will receive instructions to follow considering the scheduled appointment.
  • For some procedures you may be expected to fill your bladder.
  • The account will be submitted to your medical aid. You remain responsible for any shortfall or non-payment by your medical aid.
  • Private patients are expected to pay for the procedure on the day of the procedure.
  • If you are referred through your work, you should either produce a Letter of Guarantee or documents for WCA.
