Frequently Asked Questions:
5. When is a best time to perform an ultrasound? On each pregnancy, we like to perform three ultrasounds. The first ultrasound is performed endovaginally at 11- 14 weeks looking at fetal number, age, and nuchal translucency (a marker for down syndrome). The second (abdominal 2D) ultrasound is performed at 20-22 weeks looking for central nervous system, cardiac, abdominal wall, urinary system abnormalities as well as placental placement, umbilical vessels, and cord insertions. This is also a good time for measurements of fetal biparietal diameter, head circumference, abdominal circumference and femur length to ascertain appropriate fetal growth. If the baby is cooperating, we should be able to glimpse at the sex at this time. We like to perform the 3D ultrasound at 28-30 weeks as this is the best time to obtain images of the face looking for clefts, and of limbs looking at toes and fingers. We will also perform a 2D scan at this time to confirm appropriate growth, check placental placement and adequacy of amniotic fluid. Additional ultrasound scans are performed throughout pregnancy with appropriate medical indication. We prefer to perform the gynecologic ultrasound at cycle day 5-10; but, most gynecologic exam can be performed anytime. Exceptions include sonohysterography which should be performed after bleeding has stopped, and follicular scan for infertility which is very cycle day specific.
