Unit 21 Understanding Multiple Gestations Zygosity, Chorionicity, Amnionicity

This educational unit teaches sonographers how to determine zygosity, chorionicity, and amnionicity in multiple gestations, which are critical factors for assessing pregnancy risks and management. Students will learn to identify whether twins are monozygotic or dizygotic through ultrasound findings, understand how the timing of embryonic splitting affects placental and amniotic sac configurations, and recognize complications associated with different multiple gestation types.
