What To Expect

When having an Ultrasound, the sonographer will apply a warm coupling gel to your skin.  This gel helps to direct or steer the soundwaves by eliminating the microscopic air barrier between your skin and the transducer or the camera. A slight to moderate pressure may be applied to enhance image quality.

Antenatal / Obstetric Ultrasounds

Antenatal Ultrasounds

Early First Trimester

Best performed at 7 weeks or after.

The developing foetus, gestational sac, yolk sac/placenta and the mother’s uterus, endometrium, cervix and ovaries are scanned.

Will take around 20 minutes.

Nuchal Translucency or Downs Syndrome Ultrasound

Best performed between 12 weeks 3 days gestation and 13 weeks 4 days gestation.

The Nuchal Translucency Ultrasound checks the developing foetus for soft markers of the three most common genetic defects: Down’s Syndrome, Turner’s Syndrome and Edward’s Syndrome, as well as assessing the health of the Maternal uterus, ovaries, cervix, the placenta and umbilical cord.

Will take around 40 minutes.

Limited Anatomy Ultrasound

Best performed between 12 weeks and 16 weeks gestation.

Used to check the anatomy of the foetus that is visible at this time, the placenta and umbilical cord, as well as the Maternal cervix, uterus and ovaries. 

This ultrasound scan can be performed for women undergoing NIPT or HARMONY genetic testing. 

Will take around 40 minutes.

Second Trimester Ultrasound

Best performed at 20 weeks, but can be performed at anytime between 17 and 22 weeks.

Used to check the anatomy of the foetus.  Measurements will be taken to assess the growth of the foetus.  Detailed ultrasound images of the foetal brain, spine, kidneys and heart are just some of the areas we assess. Again, the Maternal uterus and ovaries are assessed as is the Placenta and umbilical cord.

The gender of the foetus can be given at this time.  Note should be made that gender is a subjective determination that can be limited and is NOT always accurate,no matter how hard the sonographer tries to see.  It is the least important aspect of this medical exam and is given to the parents as a courtesy.

Will take around 60 minutes.

Third Trimester Ultrasound

Best performed at 22 weeks.

Used to assess the foetus’ general health and growth as well as checking the placenta, blood flow through the foetal umbilical cord and sometimes the blood vessels in the foetal brain.  The Maternal Cervix, uterus and ovaries are also assessed.

The Nuchal Test requires a specific blood test that is used in conjunction with the Ultrasound findings to assess the foetus for these syndromes.

Will take around 30-40 minutes.

Transvaginal Ultrasound

Before 35 weeks of gestation during any antenatal ultrasounds, a transvaginal ultrasound approach may sometimes be needed to accurately measure the maternal cervix and/or obtain precise measurements of the foetus.  At 35 weeks’ gestation and after, NO transvaginal ultrasound approach will be undertaken.

The transvaginal ultrasound approach in pregnancy is perfectly safe for both the mother and the developing pregnancy. To date, there are no recorded biological effects on pregnancy in the 30 years transvaginal ultrasound approach has been used.

Preparation Information

  • Arrive 15 to 20 mins before your stated ultrasound appointment time to allow time for check in at reception and to fill in any paperwork that may be needed.

    Wear loose comfortable clothing. 

    Bring any relevant prior imaging and ultrasound reports you may have had.

    Ultrasound Scans will take between 10 mins to 1 hour depending on the type of ultrasound or ultrasound guided Interventional Procedure.

    Follow any “prep” provided to you when you booked your ultrasound appointment and / or view additional, specific information below. 

  • One hour prior to your appointment, empty your bladder.  Then drink 1 litre of water and please refrain from emptying it until after the ultrasound.

    At Precision Radiology, you are allowed 1 visitor with you during your baby ultrasound. Please leave small children at home. Obstetric Ultrasound are very important for monitoring the developing foetus and mother’s health in pregnancy. Our sonographer needs to give you and your baby their full attention.

    Obstetric ultrasound scans will take between 20 to 60 mins (longer for multiples / twins).

    Please bring a 1 GB memory stick if you would like to take home some pictures of your baby.

  • You will need to bring specific information if you have used IVF,Fresh or Frozen embryo, and date of transfer.

    Please bring your Nuchal Translucency Blood test results on the day of your exam.

    Note that HARMONY NIPT bloods are not used for the NUCHAL translucency ultrasound - please advise reception if you have had HARMONY NIPT testing.

  • Please fast for 8 hours for adults.  Children under age 10 fast for 4 hours.

    If you are diabetic then please inform the receptionist at time of booking so you can have your ultrasound scan first thing in the morning

    Eat or drink nothing other than plain water, black coffee/tea.  Please refrain from chewing gum and smoking during this time as well.  

    The Abdominal Ultrasound will take about 20 mins.  Your liver, gallbladder, pancreas, kidneys, spleen, bile ducts and sometimes bowel will be imaged.

  • One hour prior to your appointment, empty your bladder.  Then drink 1 litre of water and please refrain from emptying your bladder until after the ultrasound.

    The uterus, endometrium, cervix and ovaries are imaged. 

    Most Female Pelvis exams require a Transvaginal Ultrasound approach where a specially designed ultrasound transducer is placed in the vagina to give a much more detailed  and clearer picture of structures deep within the pelvis. This is like a “pap” smear and should not be painful. It will only take a few minutes and the ultrasound exam can be stopped any time you wish.

    If you wish to have a chaperone during your Transvaginal Ultrasound, please let the reception staff or sonographer at Precision Radiology know prior to your ultrasound.

     Your caring Sonographer/Radiologist will explain the Transvaginal Ultrasound portion of your exam to you in detail and obtain your consent.

    Reasons not to have the Transvaginal portion of your pelvic ultrasound

    • You have never been sexually active

    • You are not comfortable with the idea of a transvaginal ultrasound

    Your pelvic ultrasound scan will take about 20 mins

  • This ultrasound is used to evaluate tendons, ligaments, muscles and look for fluid in bursas and joints

    There is no specific prep needed for these ultrasounds.  Just wear loose comfortable clothing that allows access to the body part that requires an ultrasound.  You may need to change into a gown for certain areas like the shoulder or hip ultrasound.

    Musculoskeletal ultrasound will take 20 mins.

  • One hour prior to your ultrasound appointment, empty your bladder.  Then drink 1 litre of water and please refrain from emptying your bladder until after the ultrasound.

    Renal or KUB (kidneys, ureter, bladder) exam will take about 20 mins.  Images of your kidneys, ureters and bladder will be taken and the prostate is also imaged for our male patient’s.

  • Vascular ultrasound looks at the blood vessels, and assesses for varicose veins, clots and blockages. The machine may make strange noises. Don’t let this worry you. It is a normal part of the vascular ultrasound.

    There is no specific prep needed for these vascular ultrasound exams.

    Please wear loose comfortable clothing.

    Vascular ultrasound will take between 30min to 1 hour.

“I had an ultrasound done at Precision, I called in to book and the receptionist was very kind! She got me in first thing the following morning. The office is very welcoming and clean. The ultrasound tech was friendly and well informed. It was the easiest and nicest ultrasound experience I've ever had. I'll definitely come here again when I need to!”
