Our Ultrasound Unit offers most of your needed Sonography in our offices. Using state of the art ultrasound equipment, you and your partner can share in the experience of seeing your baby grow and mark the milestones in their development as your pregnancy progresses.
Here are the times in your pregnancy that you can expect or request sonography. Remember that these sonograms are for normal pregnancies. We may use special purpose sonography based on your individual risk factors (example: history of early delivery, prior surgery on your cervix, gestational diabetes, advance maternal age, etc.).
|Sonogram Type||Gestational age|
|Early Pregnancy and Dating||6 to 10 Weeks|
|Nuchal Translucency Screening||11 to 13 Weeks + 6 Days|
|Fetal Anatomy||19 to 21 Weeks|
|Growth Sonogram||30 to 34 Weeks|
EARLY PREGNANCY and DATING Sonogram
The first early ultrasound scan provides you with important information regarding the number of babies and the expected date of delivery. The presence of a pregnancy and detection of the fetal heart can be seen from 6 weeks gestation by vaginal scan and from 8-9 weeks by abdominal scan. Accurate measurements and images are taken of the gestational sac, the crown to rump length.
Combined Screening Test
We offer serum blood screening in early pregnancy in combination with nuchal scanning and maternal age in order to identify pregnancies at high risk of complications/abnormalities. The combination of these factors allows the detection of about 85% of Down’s Syndrome cases and also those at high risk for Edwards Syndrome (Trisomy 18). This test is performed between 11-13 weeks gestation and if the results show an increased risk, a diagnostic test is offered such as chorionic villus sampling from 11 weeks or amniocentesis after 15 weeks.
Fetal Anatomy Scan
Between 19-21 weeks the anatomy of your baby is scanned in detail so that any information about the many body systems, such as the urinary tract, digestive tract, heart and major blood vessels, brain and others, can be imaged and interpreted. The careful and accurate measurements made during the scan help to monitor the well-being of your baby.
This scan will tell us that your baby is growing as expected. We follow along with a tape measure on the outside but this scan give us a much more accurate idea about the baby’s growth and will give us an early warning if all is not as anticipated.
