Our ultrasounds

Ultrasound at Prenato

Ultrasound scans are precious moments for expectant parents. Prenato offers a complete range of ultrasounds during pregnancy. These are performed by experienced obstetrical ultrasound technologists. In addition to offering you a unique and personalized experience, these healthcare professionals are responsible for providing a maximum number of quality images to the obstetrician-gynecologists who will interpret them and make recommendations to your healthcare professional.


We provide time slots that allow enough time for you to enjoy a gentle experience, all in a warm atmosphere. You’ll be able to choose a few photos to print as a souvenir.


Our team of nurses will be there for you if needed. They will be able to support you and quickly follow up with your treating professional if the situation requires it.


Ultrasound scans at Prenato are reimbursable, in whole or in part, by most collective insurance plans.


As these are medical examinations, a prescription is required for each ultrasound service (except for the 3D recreational ultrasound).

It allows us to take certain measurements of your baby, to visualize your ovaries and uterus, and to take several images and videos of your baby in order to screen for any potential anomalies.
