Q: What's the difference between a Level 1 and Level 2 ultrasound?
A: Ultrasound is a diagnostic technique that uses sound waves produced by a small crystal that bounce off internal tissues to create images of the fetus. A Level 1 ultrasound can determine the number of fetuses, where they're positioned, size, placental location, amniotic fluid volume, and any grossly evident abnormalities. A Level 2 ultrasound is a more detailed and time-consuming examination that focuses closely on fetal anatomy with the specific aim of identifying any malformations.
