The 18-22 wk. detailed fetal anatomy or mid-trimester scan<br />
This has been the traditional ultrasound examination done in all pregnancies, and if you had only one<br />
ultrasound in your pregnancy, this is the one to get. It is not as accurate as first trimester ultrasound for<br />
dating, but it can still help finding discrepancies between expected dates and the size of the baby. This<br />
examination looks at the uterus, placenta, cervix, amniotic fluid and at the fetal anatomy (from head to toe)<br />
and can identify some congenital anomalies and soft markers. Soft markers are ultrasound findings that<br />
can increase the risk of the baby having trisomy 21 or 18 or other genetic conditions. Soft markers are<br />
common and are also seen in normal pregnancies. If soft markers are noted, you might discuss with your<br />
healthcare provider and decide if this information is meaningful to you, and if so, what other tests could be<br />
done to give you a more accurate answer about the genetic makeup of your baby.<br />
