Understanding Prenatal Ultrasounds
Prenatal Ultrasound imaging uses high-frequency sound waves to produce images of your baby and related structures.
An ultrasound technologist (sonographer) places the transducer (probe) and some ultrasound gel on the abdomen. High-frequency sound waves are sent and received by the transducer, then converted to real-time images on the ultrasound machine. The dynamic nature of ultrasound allows both still images and live image clips to be captured.
Did you know...
Prenatal Ultrasound uses sound waves to create real-time images of a developing fetus, allowing for safe and essential monitoring of fetal growth and development.
What We Evaluate During Your Scan
During your pregnancy, ultrasound imaging is carefully used to examine the amniotic sac, placenta, ovaries, and the baby's structural development. Specifically, these exams allow us to:
Monitor Your Baby’s Growth & Well-Being
Determine Gestational Age
Reveal The Gender Of Your Baby (Upon Request)
Important Information Concerning Your Prenatal Ultrasound
Seeing your baby is exciting, but we also know that your visit is a formal medical examination and that must be our priority.
We will provide you with pictures of your baby at the end of the exam.
During the examination, we request that you allow the technologist to concentrate on and perform the ultrasound scan. A radiologist interprets images taken by the technologist and your doctor will receive the report.
One support person is welcome to sit at the head of the bed while the exam is performed. Those accompanied by children are asked to remain in the waiting room. Your children and other observers are welcome to come in to view the baby after the medical exam is complete.
We will only reveal the gender of your baby if it is requested. Please be prepared that sometimes the fetal position, as well as age of the baby, may make this impossible.
Preparing For Your Appointment
PATIENT PREPARATION
- Dress comfortably, with loose, easy to remove, clothing.
- You may be asked to change into a gown.
- Jewelry will have to be removed from the region of interest.
- Preparation for each exam is found below. Specific preparation for pediatric patients will be given at the time of booking.
- You may eat and take medications as usual prior to your exam.
- You are required to have a full bladder for this exam. Have 1000 ml (4 cups) of water completed 1 hour prior to your appointment time and DO NOT empty your bladder. Once the initial images of your full bladder are taken, you’ll be able to empty.
- If endovaginal imaging is required, you’ll be asked to empty your bladder prior to the additional endovaginal imaging.
- Specifically for Combined First Trimester Screen (FTS or Nuchal)
- Your weight will be taken and you will be asked a series of questions related to your pregnancy history.
- Following the ultrasound exam, you will be given a lab requisition to have your blood drawn the same day.

Common Questions About Ultrasound (Pregnancy)

If you are travelling for an appointment at one of our Red Deer or Drayton Valley locations, please ask our team about these special rates when booking.
Do I need a referral from a physician?
Yes, for all exams, a valid referral (requisition) from a licensed physician or nurse practitioner is required. We cannot perform your service without this referral.
Can I pay for a private Prenatal Ultrasound in Alberta?
No, in alignment with the Canada Health Act, nearly all diagnostic Prenatal Ultrasound exams performed at our facility are considered medically necessary insured services and therefore cannot be privately paid for to bypass public wait times. Our scheduling system prioritizes clinical urgency. Elective “entertainment” ultrasounds (e.g., solely for gender reveal without medical indication) are not offered.
Can family or friends join me during my Ultrasound?
We understand you may wish to share your Ultrasound experience. For Prenatal Ultrasounds, we are pleased to allow one support person into the exam room with you. For other types of Ultrasound exams, we evaluate requests to bring a support person into the exam room on a case-by-case basis, depending on the patient’s emotional or physical needs and the nature of the examination.
Please note that policies can change based on public health guidelines (e.g., during a pandemic), so it’s always best to confirm with our booking staff.
At what gestational age can baby gender be determined by ultrasound?
The gender of your baby can often be determined during your detailed fetal anatomy scan, which is typically performed around 18-22 weeks of pregnancy. However, clear visualization depends entirely on the baby’s position during the ultrasound exam. Our sonographer will only reveal the gender if you explicitly wish to know, and if they can clearly and confidently identify it.
Why is a full bladder required for some ultrasounds?
For certain ultrasound exams, particularly those of the pelvis (like early pregnancy scans or gynaecological ultrasounds), having a full bladder is crucial.
A full bladder helps to push bowel loops out of the way, creating a clear “acoustic window” that allows the sound waves to travel more effectively, providing better visualization of the structures in your pelvis, such as the uterus, ovaries, and early pregnancy sac.
You will typically be asked to drink 32 ounces (approximately 1 liter) of water an hour before your appointment.
Can I get keepsake photos from my Prenatal Ultrasound?
Yes! We understand how special it is to see your baby’s first images. Your sonographer will do their very best to capture some clear, high-quality keepsake pictures, which we’ll email to you or send directly to your phone. Please understand that image quality can vary depending on the baby’s position and gestational age.
