Ultrasound Anatomy Scan Level 2 Ultrasound
Details, details! This special ultrasound gives you a very specific glimpse of your growing baby.
What it screens for: The ultrasound anatomy scan, or level 2 ultrasound, is an amazingly interesting experience for parents-to-be. Your baby will be measured from crown to rump (and what a cute rump it is!), around her middle, around her head — and that's just for starters. The four chambers of the heart will be viewed, as well as the kidneys, bladder, stomach, brain, spine, and sex organs (be sure to tell your sonographer if you don't want to know what he or she sees — or doesn't see!).
Measurements are taken to make sure your baby is growing appropriately (and that his or her gestational age is still on target). A survey of the organs, including the umbilical cord, ensures that they are developing normally (or identifies any potential problems as soon as possible). The sonographer will also be looking at your amniotic fluid levels, the location of the placenta, and the fetal heart rate. Settle in to enjoy the show: The detailed level 2 scan can take 30 to 45 minutes (depending on how cooperative your little one wants to be during the photo shoot).
Who it's for: Most practitioners order a level 2 ultrasound for all their moms-to-be.
How it's done: You recline on an exam table with your belly exposed. A sonographer applies gel and then moves the transducer over your abdomen. As sound waves emitted from the transducer bounce off "structures" inside (like your baby's adorable face!), images are formed on a video screen. To get the most comprehensive assessment, the sonographer will be aiming for many different views from lots of different angles in this scan. When the technician gets a clear shot, he or she will freeze-frame the picture (that's the actual sonogram) and then measure the anatomy. You can expect to go home with one or two good sonogram pictures (the perinatologist and your practitioner will review the rest).
When it's done: Most level 2 ultrasounds are performed between 18 and 22 weeks. If you have a condition that needs to be monitored (such as carrying twins), you may have more than one detailed ultrasound.
Risks: There are no significant risks associated with ultrasounds, though medical guidelines caution against unnecessary exposure to ultrasound — which is why your practitioner will schedule only a handful of them throughout your pregnancy.
