Ultrasound & Doppler

  • Using Ultrasound for imaging is the oldest and most frequently used form of medical imaging. 
  • It involves a painless medical test that assists doctors to diagnose and treat a variety of medical conditions.
  • Investigation of abdominal pain, a palpable mass, gallbladder and kidney stones as well as a multitude of other conditions is easily done with an Ultrasound. 
  • It is a fast, cost-effective examination without any radiation.
  • Ultrasounds:
    • Are easy to use and mostly painless and non-invasive.
    • Do not use ionising radiation (and is therefore safe during pregnancy).
    • Give a clear picture of the soft tissue, often not visible on X-Ray
    • Have many applications.
    • Have no known harmful effects on humans.
General Information
  • Gross obesity may interfere with the technical quality of the Ultrasound study.
  • Nowadays an examination of the muscular-skeletal system and blood vessels also forms part of the routine Ultrasound imaging portfolio.
  • Other applications include soft tissue evaluation of the breasts, neck, thyroid and scrotum.
  • Interventional procedures performed under Ultrasound guidance have now almost become a routine procedure.
Before your Ultrasound examination
  • Please arrive 15 minutes early to complete all the necessary paperwork.
  • You can also download the patient information form here. 
  • Any garments with metal zippers, belts or buttons and jewelry may interfere with Ultrasound images. You will therefore be required to wear the gown provided.
Special Preparation

 Abdominal Ultrasound

  • Nil per mouth 6 hours prior to exam (eating introduces air into the stomach and bowel, complicating visualisation of the target organs and also causes the gallbladder to collapse).
  • Water and medication may be taken.
  • Please arrive with a full bladder by drinking 2 litres (4 to 6) glasses of water at least an hour before your examination. Sound waves travel through liquids and subsequently the full bladder. A full bladder also pushes bowel gas away from the organs that are being examined, enabling visualisation of the uterus and ovaries or prostate behind the bladder. 

Pelvis/kidney Ultrasound

  • Eat and drink as normal.
  • Please arrive with a full bladder by drinking 2 litres (4 to 6) glasses of water at least an hour before your examination. Sound waves travel through liquids and subsequently the full bladder. A full bladder also pushes bowel gas away from the organs that are being examined, enabling visualisation of the uterus and ovaries or prostate behind the bladder. 
Let the Sonographer know
  • If you did not follow the special preparation instructions as prescribed.
  • If you have any medical conditions, such as allergies, diabetes, heart conditions or glaucoma.
  • Of any previous relevant surgical procedures.
What to expect
  • SCP Ultrasound and Doppler examinations are performed by qualified Sonographers and Radiologists.
  • You will be lying face-up on an examination table for most examinations. For some other studies, such as a shoulder study, you may be required to sit up.
  • A clear gel is supplied to the area to secure contact and eliminate air between the skin and transducer.
  • You may be requested to hold your breath, for intermittent periods of time, during upper abdominal studies (gallbladder, liver, spleen, pancreas and kidneys)
  • For best results:
    • Please adhere to preparation procedures, especially pertaining to not eating or drinking before an abdominal study and arriving with a full bladder for a study of the pelvis or kidneys.
After your Ultrasound examination
  • After the procedure, you will have to wait briefly while images are reviewed. 
  • You can return to your normal routine right away, unless you are advised not to.
