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.

The ultrasound can be used during pregnancy to show images of the baby, amniotic sac, placenta, and ovaries.

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.
