what is ob us limited fetus
Location: Alberta. Posts: 26,458. A limited obstetrical ultrasound is just a basic quickie-the location, fetus age, fetus size, and measurements/due date. It's very fast, basically a check to see if there is a pregnancy and what kind/if it is viable.A non-limited one would be the 20-30 minute extensive anomoly ultrasound you get at 20 weeks to determine any fetal health issues.Status: Offline. limited obstetrical ultrasound is just a basic quickie-the location, fetus age, fetus size, and measurements/due date.
