Obstetrical Ultrasounds

Using state-of-the-art ultrasound equipment, you can share the experience of seeing your baby grow and mark the milestones in their development throughout your pregnancy. Obstetrical ultrasounds are typically performed vaginally until after 10 weeks, and they are done with an empty bladder.

Ultrasound Timeline During Pregnancy

Here are the types of ultrasounds you can expect during a normal pregnancy:

Early Pregnancy and Dating Ultrasound

The first early ultrasound provides essential information about the number of babies and the expected delivery date. The presence of a pregnancy and the detection of the fetal heartbeat can be seen as early as 6 weeks gestation via vaginal scan and 8-9 weeks via abdominal scan. Accurate measurements and images of the gestational sac and crown-to-rump length are taken.

Fetal Anatomy Scan

Between 19 and 21 weeks, a detailed anatomy scan of your baby is performed to assess various body systems, including the urinary tract, digestive tract, heart, major blood vessels, and brain. The sex of the baby can usually be determined during this ultrasound, though it may not always be visible. If a Level II ultrasound is needed, you will receive an order and will need to schedule it at the hospital.

Growth Scan

A growth scan provides a detailed assessment of your baby’s growth. While measurements taken during your visits offer a general idea, this scan provides a more accurate evaluation, allowing early detection if growth is not progressing as expected.
