Abstract

In this chapter, the most common used ultrasound images of the fetuses and the fetal appurtenances are introduced, including scan method, section structures, measuring method, normal reference values, and clinical significance. Detection method of fetal umbilical artery, middle cerebral artery, and ductus venosus is also introduced.
